A Tribe Called K2 Buhl-oog!

Written by X

I’m an independent instructor in Arizona.  I’m keeping my identity cloaked so that I can tell the buying public the truth and keep you informed. Tevis of K2 has the balls to publish this on the K2 blog. . . cheers for his courage!

The below testimonial from DiveMatrix is not an isolated incident, in fact it has been the dirty little secret of that diveshop owners have kept from the buying public.

Dive shop owners have known for years that the Henderson Hyperstretch, the most expensive the wet suit  full suit in the Henderson arsenal, only lasts for a year of cold water dives,  before its fails thermal protection.  When  I asked dive shop owner that I taught classes for, “ . . .  well isn’t this kind of crappy and for such an expensive wetsuit, and aren’t we kinda  fleecing our customers? He replied,  it keeps them coming back, and I can keep selling them the Hyperstrech year after year!”

Incidentally, he was a jerk and eventually went out of business. Good riddance!

So, in other words there is a built in failure/ obsolescence to those amazingly comfortable, mondo stretch, in this form-fitting  type F4 hybrid neoprene material.  What you achieve in comfort you eventually  gives up in the thermal protection. Said a different way, the reason why the suit is so comfortable, is because of the large diameter of the blown nitrogen bubble resident in the neoprene.

You will be able to actually witness  the role that compression plays in this K2 video, you will witness  when neoprene compresses the bubbles burst.

From the first dive, neoprene compresses, and it doesn’t uncompress, it has burst. . . . so each and every time you  descend on your dive,  you lose both thickness as well as thermal protection.

This is part and parcel of the saying that “cheap costs.”  This is a given with most cheap bargain basement wetsuit  (see chapter 9 Cheap Does Cost)  What is an anathema, is that Henderson (a great and solid company) has the one of the most expensive, retailing at $455.00. . . and it has a usability life of one year.

[Editors Note:  Henderson IS a GREAT Company, and K2 IS a Henderson Dealer.  We have included this Chapter to share with you some of the nasty little secrets that Dive shops perpetrate on the buying public.  The Hyperstretch is what it is, and for a non conforming body type diver, it is the ONLY suit that fits comfortably.  But don’t you deserve to know that your wetsuit only has a year or two worth of dives before you will need another one?]

As soon as 20 to 30 dives, you begin to lose both thickness and warmth as the neoprene bubbles burst.  After  40-60 dives,  there has been such a catastrophic loss of the neoprene bubbles that it loses its ability to keep you warm at all.

A Question of Warmth

Please read the testimonial below about the Henderson Hyperstretch 7mm.  Pay close attention to how many dives were completed before the wetsuit failed thermal protection

So, I thought I’d post my thoughts on my Henderson Hyper Stretch wet suit.

Having owned a very warm and extremely durable old neoprene (Rubatex aka N231 neoprene) 1/4 inch farmer john style Blue Water wet suit for many years, I was ready for a new suit. The old suit was built like a tank, but was a real pain to get in and out of.

My number one consideration for a replacement was comfort. I don’t get cold easily, so this was secondary. I was not really looking for durability, but would not have minded finding something durable that was extremely comfortable. I decided that a 7mm full suit would fit my needs and that for me, anything else would be overkill.

I tried many wet suits on one day and left the Henderson for the end since I had been told by quite a few people that this would probably be the most comfortable one. I tried on so many suits that I actually had blood blisters on one finger of each hand. I was exhausted and somewhat over heated. It was now time for the Henderson.

Well it popped on so easily I couldn’t believe is was really a 7mm wet suit. That was enough for me. I had found what I was looking for.

Now I’ll tell you my experience with it up to this point.

I’ve got 180 dives on it.

At about 100 dives it lost a good deal of its thermal protection. That doesn’t really bother me because I don’t get cold very easily. When it was new, I was quite comfortable for an hour long dive down to about 50º. Now it’s fine down to about 55º for about 45 minutes. From about 48º to 52º, I do notice I now get quite a bit colder than when it was new. I have not noticed that it has lost much more of its thermal protection since around 100 dives.

At around 150 dives, the zipper started to come out and I had it sewn back in at about 160 dives.

At 180 dives it’s looking a bit like swiss cheese with the biggest holes under the arms and in the knees above the knee pads. I’ve noticed that above the knee pads seems to be a common place for these to get holes in them when I see other Henderson suits around the area.

I don’t remember exactly what I paid for it, but remember it being a bit over $300.

So, what’s the bottom line? Would I buy another one?

Absolutely! The comfort level and ease of getting in and out of this thing is worth throwing it away around every 200 dives. I think it still beats the cost of ownership for a dry suit, but probably not by much.

Instead of replacing this one anytime soon, I’m going to buy a dry suit instead. Then I’ll probably get another one that I’ll only where occasionally.

Has anyone out there had a similar or very different experience with a Henderson wet suit?

Putting my flame suit on.  Bring it.  Im sure the whining will come from dive shop owners and reps that want to keep this hidden.

This is Seeded from John McKenzie of http://blog.wetcatscuba.com/?p=704

it is much too important NOT to spread this virally. . . don’t count on the manufacturers. . they don’t have your best interests in mind.

We can take care of your Dive Rite wing OPVs if you need help.  Welcome to the Tribe called K2!

By John McKenzie, on February 7th, 2010

You giant stride from the gate of the dive boat into the cold swells of the Pacific Northwest’s emerald sea. But unlike on other entries you don’t bob quickly back to the surface with your OK sign beaming. “What’s up?! I am sinking!” goes through your mind. You have an important first choice – whether or not to panic. No panic and you have some good options for recovery and more dives. Panic and you may have only a few minutes before drowning.

That was just one scenario that went through my mind upon a recent discovery while cleaning my dive gear. Thankfully I was not jumping off the back of a boat with my defective gear; instead I was in the comfort of my garage trying to understand why my Dive Rite wing was blowing air out from the lower dump valve. I shuddered as I watched the corroded spring that holds the valve closed and the air inside crumble to bits in my hand. Luckily, I dodged that bullet, as did my partner, my friend and dive shop owner Grant, and the owners of every Dive Rite wing recently inspected by another local dive shop owner at his shop.

The story I wanted to be able to write was one that told how the folks that run dive equipment companies, most likely divers themselves, are extra vigilant and responsive to safety issues with their products. I wanted to hear that upon finding one corroded stainless spring, that was never supposed to rust under any dive conditions, they immediately launched a full scale investigation and rapidly notify dive shops and customers of the potential threat to their life. That’s the responsible thing to do. And when you read this in the recall statement, “…the company is working closely with the US Consumer Product Safety Commission (CPC) and has instituted a VOLUNTARY recall…,” it spins the impression that they “recently” found a problem and are taking quick action to protect divers.

But I cannot tell that comforting story. The story of what we learned

shouts loudly this message to every diver, “If you want to maintain good odds of coming back alive, do not depend on the manufacture, the dive shop, the government recall, you must check your own gear often and have regular professional maintenance.” From our research and many news stories we have seen over the years, we can be confident that the Dive Rite OPV recall story is just one example of how the incentives for a company NOT to respond quickly to prevent injury or death can muddy the ethical waters. It is not all bad news. It does appear that months before the Dive Rite recall, Halcyon, finding the same problem, did take responsible steps in the interest of safety. But, given what we learned about the timeline at Dive Rite, it is possible the even Halcyon found bad springs well before the recall was instituted. From talking directly with Dive Rite staff there is evidence that Dive Rite was much slower to respond and may have only done a recall to cover their butts. It shows that we dare not overestimate the good folks that run our favorite dive business. The sad reality is that CYA and money fears can and often do eclipse thoughts of your safety in business.

THE PROBLEM

The spring that holds the over pressure valve (OPV or dump valve) closed on the (some unknown) number of BCD wings sold by Dive Rite (and by Halcyon and maybe other brands) was supposed to be made of quality marine grade 316 stainless steel. However, someone at an unknown factory in (wait for it…) China made some of the springs out of not so good 304 stainless steel. After a while of being immersed in saltwater, these bad springs will corrode and literally crumble to bits. Before they completely crumble the bladder will start leaking air. And if you are not one of the few divers that routinely inspect for these kind of things, you may get a leak when you are hanging from it over a significant amount of water.

We know of at least three equipment sellers that bought problem OPV springs from the same supplier. These are Dive Rite, Halcyon and Custom Buoyancy Inc. (CBI). CBI is reported to be out of business. Could there be more? The general consensus is yes. Most OPVs on scuba BCDs and other equipment look and work alike. Other suppliers could be getting their valves from the same Chinese factory. But this is a hard trail to follow. Dive Rite claimed to not know the name of the manufacturer and while admitting that divers should be warned, they flat out refused to tell us the name of their supplier. We have filed a freedom of information request with the CPSC…stay tuned.

THE RECALL STORY

As mentioned above, Halcyon came out first with the recall on October 1, 2009 (CPC date) (see our article at http://blog.wetcatscuba.com/?p=563). Our conversation with Halcyon took a much different tone than with Dive Rite. At the least, Halcyon seemed to have a culture of serious concern for their customers’ safety and an indication that they took every step to “do the right thing.” They saw the problem and instituted the recall on their own accord (although a Dive Rite marketing director said she believes Halcyon had in “incident” that prompted the recall). Halcyon staff were not sure of the quantity of bad springs, so they made the recall broad in scope to cover over 20,300 units. They later augmented the recall to ask dealers to replace springs in those units within the range, even if they showed no signs of corrosion. Our Halcyon contact said, “We realized that some units may not have been in the water long enough to corrode, but could corrode later. Why take chance for the measly price of a spring. We told dealers to replace them and we would cover it.” Unlike Dive Rite, Halcyon did not wait for or require their dealers to ask for replacements. They sent the dealers replacement springs with a log book to track replacements. They also created two informational/instructional videos and posted them on their website (see link above).

Dive Rite’s recall came in late December 2009. Why did Dive Rite wait over two months? Did it take them that long to figure out that they also had some bad springs. Not according to their own staff. One Dive Rite source admitted that they saw the problem well over a year before the recall. I was surprised that told me that they only instituted the recall because they knew that people, seeing the Halcyon recall, would sooner or later would figure out that Dive Rite springs were the same. This would look bad if they did not do a “voluntary” recall like Halcyon. He also played down the likelihood that anyone would get hurt by this problem.

Previous to this call, we spoke with another staff member of Dive Rite who also minimized the the numbers, claiming “maybe 100 world wide and only 35 in the U.S. We already had 2 cases in our house, the shop owner who sold us the wings said his was also bad. The second person I talked with was another area Dive Rite dealer. He said, “every spring we checked so far in the 2006-2208 year range tuned out to be corroded.” Other dealers reported similar findings. Now either those bad wings were highly targeted to the Pacific Northwest or our Dive Rite contact was low-balling. We later talked with another Dive Rite contact that admitted the numbers were likely much higher.

I asked Dive Rite if they have sent replacement springs out to their dealers (as Halcyon did) or do dealers have to request them? The response was, “we are sending free replacement springs to dealers, when they ask for them. We do this because we would like to get them to tell us how many they need. We don’t want to send them a pile of springs they may not need. And we need at least some of the serial numbers and counts for the CPC paper work.” During my conversations with Dive Rite, I told them that our LDS had given us a two non-dive rite springs to help get us back in the water. I also told them the shop owner’s spring was bad and he had sold a bunch of Wings within the recall period. A week later he received only four springs from Dive Rite.

After our calls to Dive Rite, the marketing director called us and complained that we were just looking to slam them. She wanted to know “who, at Dive Rite told us those things.” She then admitted that they did see bad springs 18 months before the recall, but claimed that they did take immediate action. She said they notified all dealers about the springs and put an announcement in each of their monthly newsletters since then. However, when we checked more sources we found little evidence of her claims. A former Dive Rite sales representative, who was a liaison between Dive Rite and Dive Rite dealers during the this time said he never heard about the spring problem. He sent us all of his monthly newsletters for the past year and we found no mention. Other dealers had similar stories.

THE COMPANY LINE

Here is the text from the Dive Rite site at: http://www.diverite.com/products/service/opvspringrecall/

Dive Rite takes the safety of our consumers very seriously. In cooperation with the US Consumer Product Safety Commission, Dive Rite is issuing a voluntary recall on various Dive Rite Wings.

The Over Pressurization Valve (OPV) springs found on Dive Rite wings manufactured between June 2006 and October 2008 may rust and fail allowing the buoyancy compensator devices to leak. The wings may be red, blue or black in color and have serial numbers falling between 42000 and 72000. The following models are affected by this recall: Travel, Venture, Rec, Trek, Classic, Nomad and Super Wings It does not affect EXP or 360-branded wings. The recall does not affect lift bags, surface marker tubes or other Dive Rite inflatable devices.

We apologize for any inconvenience and encourage Dive Rite wing customers to contact your local Dive Rite dealer or Dive Rite directly at 800-495-1046 with any questions.

THE MORAL OF THE STORY SHOULD BE REPEATED

Don’t be fooled into thinking this is just a story of the failings of one dive equipment manufacturer. Even for the most responsible of companies, it will still take months for them to institute an official recall. Dive equipment manufacturers need to do better. But, if you want to improve you chances of living through you next dive, get religious about checking and maintaining your own gear. We dive weekly and on every group dive trip I can remember someone on the trip had found they had some kind for equipment problem just before or during the dive.

While you do need to have a professional check your gear on a regular schedule, most of the problems found can be fixed by any diver (e.g. loose hoses, bad o-rings). The training agencies offer specialty courses to help you get more knowledgeable about maintaining your kit. This spring problem is simple to check and fix. If you find any bad springs in any other brands (or any other equipment failure patterns) let us know (john@jmckenzie.com) and we will warn our fellow divers.

The incentives for companies to take the wrong path cannot survive if divers will report problems, demand better gear and better ethics from your equipment vendors. These companies have the technology to catch problems and communicate the resolutions quickly to dealers, shops and customers and only some are doing it. You can also vote with your wallet for companies that have the good values to build safe equipment, with parts from manufacturers they know and trust, and when they do have a problem to handle it quickly and responsibly.

WARSAW, Poland (AP) – A frightened, shivering dog was rescued after floating at least 75 miles (120 kilometers) on an ice floe down Poland’s Vistula River and into the Baltic Sea, officials said Thursday.

Now his saviors just have to figure out who really owns him.

Four people have already claimed him, but so far rescuers say there’s been no wagging tail of joy from the miracle dog they nicknamed “Baltic.”

The dog’s frozen odyssey came as Poland suffers through a winter cold snap, with temperatures dipping to below minus 4 degrees Fahrenheit (minus 20 Celsius).

The thick-furred male dog was found adrift Monday 15 miles (24 kilometers) out in the Baltic Sea by the crew of the Baltica, a Polish ship of ocean scientists carrying out research.

Researcher Natalia Drgas said Thursday the rescue was difficult and at one point it seemed the dog had drowned.

“It was really a tough struggle. It kept slipping into the water and crawling back on top of the ice. At one point it vanished underwater, under the ship and we thought it was the end, but it emerged again and crawled on an ice sheet,” Drgas said.

At that point, the crew lowered a pontoon down to the water and a crew member managed to grab the dog by the scruff of his neck and pull him to safety.

Too weak to shake off the frigid water, Baltic was dried and wrapped in blankets. After he warmed up, he was massaged, fed and soon got on his feet to seek company, Drgas said.

A firefighter in Grudziadz, on the Vistula river 60 miles (100 kilometers) inland from the Bay of Gdansk, told The Associated Press the dog was spotted Saturday floating on ice through the city. Firefighters tried to save him but could not approach the dog due to shifting ice sheets, said the officer, who spoke on condition of anonymity.

The Baltica crew, now moored in the port city of Gdynia, have been searching for the dog’s owners, ship captain Jerzy Wosachlo said. So far four people have claimed him, but Baltic has not claimed any of them back, Drgas said.

The dog didn’t welcome the first two people to come for him, keeping his distance and showing no recognition toward a couple on Wednesday and a woman on Thursday who both said he was theirs. Two other would-be owners were still en route to Gdynia for a possible reunion.

Once in port, the brown-and-black mongrel was taken to a veterinarian, who found him in surprisingly good condition and estimated his age at around 5 or 6 years old. Veterinarian Aleksandra Lawniczak said the 44-pound (20-kilogram) dog was clearly frightened but in strikingly good shape and had suffered no frostbite.

A dog with thick fur and a layer of fat can survive such cold conditions for as long as eight days if it has water to drink, Lawniczak said.

She described Baltic as a friendly dog who was clearly well treated before getting lost.

Wosachlo said the research team is prepared to adopt Baltic if his original owner is never found.

WASHINGTON, D.C. — The global ocean surface temperature was the second warmest on record for December, according to scientists at NOAA’s National Climatic Data Center in Asheville, N.C. Based on records going back to 1880, the monthly NCDC analysis is part of the suite of climate services NOAA provides. Scientists also reported the combined global land and ocean surface temperature was the eighth warmest on record for December.

For 2009, global temperatures tied with 2006 as the fifth-warmest on record. Also, the earth’s land surface for 2009 was seventh-warmest (tied with 2003) and the ocean surface was fourth-warmest (tied with 2002 and 2004.)

Highlights for December 2009

• The global ocean temperature was the second warmest on record, behind 1997. The temperature anomaly was 0.97 degree F above the 20th century average of 60.4 degrees F.
• The combined global land and ocean surface temperature was the eighth warmest on record, at 0.88 degree F above the 20th century average of 54.0 degrees F.
• The global land surface temperature was 0.63 degree F above the 20th century average of 38.7 degrees F – the coolest December anomaly since 2002.

Global Temperature Highlights for 2009

• For the calendar year 2009, the global combined land and ocean surface temperature of 58.0 degrees F tied with 2006 as the fifth-warmest on record. This value is 1.01 degree F above the 20th century average.
• NCDC scientists also noted the average temperature for the decade (2000-09), 57.9 degrees F, was the warmest on record surpassing the 1990-99 average of 57.7 degrees F. value.

Other Highlights

• Arctic sea ice covered an average of 4.8 million square miles during December. This is 6.6 percent below the 1979-2000 average extent and the fourth lowest December extent since records began in 1979.
• Antarctic sea ice extent in December was 2.1 percent above the 1979-2000 average, resulting in the 14th largest December extent on record. December Arctic sea ice extent has decreased by 3.3 percent per decade since 1979, while December Antarctic sea ice extent has increased by 0.6 percent per decade over the same period.
• Northern Hemisphere snow cover during December 2009 was the second largest extent, behind 1985, on record. North American snow cover for December 2009 was the largest extent since satellite records began in 1967.

NCDC’s preliminary reports, which assess the current state of the climate, are released soon after the end of each month. These analyses are based on preliminary data, which are subject to revision. Additional quality control is applied to the data when late reports are received several weeks after the end of the month and as increased scientific methods improve NCDC’s processing algorithms.

Scientists, researchers and leaders in government and industry use NCDC’s monthly reports to help track trends and other changes in the world’s climate. The data have a wide range of practical uses, from helping farmers know what to plant, to guiding resources managers with critical decisions about water, energy and other vital assets.

NOAA understands and predicts changes in the Earth’s environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources.

Here’s another Butterflyfish from Hawaii. This one is called the Milletseed Butterflyfish (Chaetodon miliaris), although you also may see it identified in some picture books as the Lemon Butterflyfish. Which common name you prefer may depend on whether you focus on its lemony background color, or its vertical rows of black spots.  The scientist who named the species focused on the spots, which he thought resembled milletseeds, hence  the species name miliaris.

Like the Multiband Butterflyfish (Chaetodon multicinctus) that we presented in the previous post, C. miliaris is a Hawaiian endemic species.  In fact, the two species are closely related, both belonging to the subgenus Exornator. Nevertheless, the behavior of the two species is different in several ways.

Most conspicuously, the Milletseed Butterflyfish lives in aggregations instead of in pairs, and they are not territorial. It is not uncommon to see whole mobs of these bright yellow fishies moving along the reef together, looking for food.  Now,  ”mob” is hardly a scientific term, but it suits shoals of Milletseed Butterflyfish.  Unlike some other fishes that school and move along in an orderly way, almost in unison, the Milletseeds move along together in an almost rowdy fashion — but  I must say, that is a wonderful sight to behold.

Milletseed Butterflyfish have a much more varied diet than C. multicinctus. Their preferred food is zooplankton, but they also will eat the eggs of other fishes — especially those of fishes that deposit egg masses on rocks and other surfaces.  Milletseeds sometimes perform as cleaners of other fishes, too.

The Milletseed Butterflyfish occurs naturally only in Hawaii, but it is not rare in the islands.  In fact, C. miliaris is said to be the most common among the 24 species of the Butterflyfish family (Chaetodontidae)  found in the Hawaiian islands.  If you dive or snorkel in coral reef environments in Hawaii you are almost certain to encounter a ‘mob’ of these yellow beauties.
