ZEOS and HYDROS wings recall

A recent recall has been updated and now only applies to the ZEOS 28 Single Wing. All ZEOS 28 Wings are now being recalled.

Please read the information below carefully. If you have one or more ZEOS 28 wings, you should immediately stop using it due to a drowning hazard and follow the procedure below to obtain a brand new replacement ZEOS 28 wing.

Please read the information below carefully. If you have one or more ZEOS 28 wings, you should immediately stop using it due to a drowning hazard and follow the procedure below to obtain a brand new replacement ZEOS 28 wing.

A few days ago we announced the recall of ZEOS and HYDROS wings from specific series manufactured since January 2013. The reason was some material issues that led to delamination of the base fabric and coating in the internal bladder. The result of this was that the welds on some areas had separated leading to loss of gas from the bladder. All of the materials are quality inspected before manufacturing but it took some active use before this issue showed itself.

During further investigation of the manufacturing documentation, we have found, that only ZEOS 28 wings may be affected as this part of fabric was used only to manufacture this specific model. As we are Tec divers ourselves and therefore take every safety-related issue extremely serious and we want to be sure that all of the XDEEP wings that are in use meet our very high quality and safety standards.

The Zeos 38, Hydros 40 and Hydros 50 are no longer subject to the recall and can continue to be used.

The safety of our customers is the most important thing for us. We also really want to minimise the inconvenience to our customers as much as possible. We have therefore decided that we will completely replace all ZEOS 28 wings for brand new ones, even though it is only one part which may be affected. We sincerely hope that this option to own a brand new wing will compensate for the trouble.

Why did we decide to make a recall and replace the ZEOS 28 wings?

Cock-ups Officially the Funniest Part of Scuba Diving

Groundbreaking research at The Scuba Monkey’s top-secret labs (off the A3 near Horsham) has discovered that watching someone make a complete pig’s ear of a buddy check or giant stride entry is scientifically proven to be the funniest thing in scuba diving.

This new research overturns previous thoughts on the subject undertaken during the 1990’s that had indicated that seeing someone end up with a bird’s nest of line at 5m when trying to deploy an SMB and bobbing up and down like a yo-yo was the incident most likely to cause someone to laugh into their mouthpiece.

The Scuba Monkey’s research team spoke with leading industry figures who confirmed the findings:

Overcome the Fear of Having Water in Your Scuba Mask


Dive Skills

Dive Skills

I wasn’t always calm and controlled underwater. I still remember my initial reaction to the mask flooding skill in the open water course: terror. “Why would I ever put water into my mask on purpose?” I asked my scuba instructor. It sounded crazy. My instructor explained that there was significant value in this skill. Water leaking into a scuba mask is a common occurrence. A diver must become comfortable with water in his mask so that he will maintain control and avoid panic. Situations exist in which a diver may even choose to allow a small amount of water to enter his mask during a dive. For example, swishing a small amount of water around the interior of the mask removes fog from the lenses during a dive. Here are tips on how to overcome the fear of water in the scuba mask.

Fear Management Step 1: Practice Breathing Without a Mask on the Surface:

If the thought of water in the mask scares you silly, your are not alone. The first step in overcoming your fear is to prove to yourself that you can breathe without a mask at all. This step develops confidence that you won’t die underwater without a mask on, and that it is possible to breathe with water surrounding your nose.

Stand, kneel, or sit in shallow water. While breathing from a scuba regulator or a snorkel, but without using a mask, lower your face into the water. Practice breathing slowly and calmly. Inhale and exhale with your mouth. If you feel water entering your nose, breathe in your mouth and out your nose.

Breathing in this manner may feel uncomfortable at first, but stick with it. Remember that you are in control, and that you can lift your face out of the water whenever you like. Practice this skill until breathing though a regulator or snorkel with your face submerged feels routine.

Hint: This skill can even be done with a snorkel in a bathtub at home. With no people watching, there is less pressure from instructors and other students.

Fear Management Step 2: Do “Dry” Runs:

After proving to yourself that you won’t immediately drown when breathing with your nose in the water, you need to develop confidence in your mask clearing skills. Having water in your mask is less scary when you are sure that you can quickly and efficiently remove it.

Underwater (under the supervision of an instructor, if this is your first time) practice the breath control required for mask clearing. Hold the upper frame of the mask against your forehead, look up, and breathe out your nose with a long, slow exhalation. Air should bubble out from the lower portion of the mask. Have an instructor or buddy observe your practice and provide feedback. Practice inhaling with your mouth and breathing out your nose until the breathing pattern is second nature.

Fear Management Step 3: Baby Steps:

When training yourself to become comfortable with water in your mask, put only a small amount of water into the mask at first. Pinch the top seal of the mask gently between two fingers and allow a few drops of water to trickle in. Do not fill the mask to eye-level on your first try. Practice emptying the mask of this tiny amount of water. As you become comfortable, fill the mask more and more until you can comfortably clear a fully flooded mask. Only after becoming confident clearing a fully flooded mask should you practice removing the mask and replacing it underwater.

Fear Management Step 4: Practice Repetitively in Calm, Shallow Water:

Before hitting the ocean (or even the deep end of the pool) practice allowing water into your mask and blowing it out until you are bored with the skill. Practice clearing the mask of water in different positions: swimming, hovering, laying on the floor, etc. The point is to make this simple skill routine, and to gain muscle memory. Once you can preform the skill mindlessly you will no longer panic when water enters your mask. Your immediate reaction to water in your mask will be to calmly and efficiently blow the water out. However, multiple repetitions are required to reach this level of proficiency.

Fear Management Step 5: Put Water in Your Mask on Every Dive — On Purpose!:

The key to mastering scuba diving skills is repetition and practice. A proficient diver can execute diving skills automatically without fear or hesitation. Of course, many diving skills require a series of steps which must be practiced deliberately at first, but with repeated practice, even a complicated skill becomes automatic.

With this in mind, consider that your work is not done once you have become comfortable with water in your mask. Even if you have overcome your fear, you must periodically reinforce your confidence by allowing water into your mask and clearing it. A diver who is nervous about water in his mask should purposefully flood his mask on every dive. Not only does he reinforce the skill (See, I can still do it!) but repetition over a long period of time will strengthen his muscle memory and ensure that he reacts properly in an unexpected situation.

Fear Management Step 6: Mind Games:

I finally became very comfortable with water in my mask during my Divemaster course, during which I was asked to demonstrate mask removal and clearing and make it look easy and fun. I learned an interesting mind trick – when I had the mindset of demonstrating (or showing off) I lost any residual fear of water in my mask and instead focused my energy on how to look professional. How slowly could I clear my mask? How controlled? Could I maintain buoyancy and trim (body position) while demonstrating? By taking the focus off of “Aughhh, there is water in my mask!” and instead focusing on making the skill look good, the fear of water in the mask was replaced by fear of looking like an idiot. I sometimes recommend this mind trick to students. I ask them to imagine they are demonstrating the skill for a diver who is even more afraid of water in the mask than they are, and try to make it look like no big deal. It doesn’t work for everyone, but this mind trick worked for me!

The Final Word on Getting Over the Fear of Water in the Mask:

As in most scary situations in life, the best way to overcome the fear of water in your mask is to face the situation, not ignore it. A person who is scared of water entering his mask is unlikely to react properly in the event that his mask floods during a dive. He may bolt for the surface or panic underwater, either of which is unsafe. Work your way up to putting water in your mask by proving to yourself that you can breathe safely on the surface with no mask, and that you can breathe out your nose to clear a mask properly. Then, begin with small amounts of water and practice repetitively until you are bored before adding more water to the mask. Work at your own pace and do not push yourself into a panic situation. Take it easy – with time and patience you can overcome this fear. Once you become confident clearing the mask, practice mask flooding or mask removal with a buddy on every dive to keep the skill (and your confidence) fresh.

Scuba Diving Equipment – What To Look For When Buying Used Scuba Tanks


Dive Tanks available @ kirkscubagear

Dive Tanks available @ kirkscubagear

The time eventually comes when every serious diver decides to get their own tanks. Tanks are usually the last item on the list for a diver to purchase. They are expensive to buy new and used ones can have their own problems (more on that shortly).

It’s hard to beat having a couple tanks out in your garage, ready to go when a dive opportunity presents itself. This is especially the case if you do not live near a dive shop and most of the diving you do is remote.

The number one reason to have your own tanks is convenience. It’s nice not having to reserve rentals, pick them up and then get them back to the shop after the dive. You can refill your tanks when its convenient.

If you are looking for a deal, used is the way to go. That being said, there are some pitfalls you will need to avoid when buying pre-owned tanks. The best bet is to get your used tanks from a dive shop. For the deals, check craigslist or a local dive board.

The key to a successful buy is that the tanks have a current hydro and visual inspection. If you are buying from a shop, this should be included. If you are buying from an individual, you need to confirm that these are current. One tip for scoring a great deal is to start looking for used tanks around December. I have found some amazing deals in the dead of winter. I wonder why?

A visual inspection and hydro will cost you as much as $50 per tank. This expense alone may bring the total price up to what you would pay for a new tank. You may also need to replace the valve. Ensure the visual sticker is present and that there is a hydro stamp on the tank.

Some “older” tanks aluminum are considered suspect and your local shop may not fill them. A number of tanks manufactured in 1990 and earlier have been known to rupture (explode). Be sure to consult with your local shop before purchasing.

Steel or Aluminum? My preference is steel. Steel is durable and if properly cared for can last for decades. They are also more neutral during the course of a dive. There are not as many concerns with older steel tanks as there are with aluminum. For whatever reason there are deals to be had on used steel tanks.

Unlike aluminum, steel tanks are prone to rust and may need to be tumbled or brushed if there is any corrosion present. You may need to have this done annually. Aluminum is hard to beat from a maintenance perspective. It does oxidize but it’s not as big a deal as rust.

What about new tanks? New 80 CF tanks run about $250 with a valve, minus the inspection. Steel tanks will cost about $350. Get them at a shop and they will (most likely) include the inspection and a fill.

Whatever you decide, owning your tanks can take your diving to a new level.

The Combined Effects of Increased Levels of Carbon Dioxide and Breathing Resistance Caused by Underwater Breathing Apparatuses


dive53:

Excellent Read!

Originally posted on The Dive Lab:

ONR_Book1 (2)Between July 15-17, the Office of Naval Research (ONR) and the Naval Sea Systems Command (NAVSEA) hosted an undersea medicine progress review meeting in Durham, North Carolina. The presentations focused primarily on topics of interest for the Navy, but most of the research also benefits recreational and technical divers. One topic I found particularly interesting concerns the combined effect of increased carbon dioxide levels (CO2) in breathing gas and the breathing resistance that breathing apparatuses impose on divers.

If breathing is unimpeded, slightly increased levels of CO2 pose no problem. However, the more CO2 that is inhaled, the less CO2 can be added, and a larger breathing volume per unit of time will be required to wash out the same amount of CO2. This increase of breathing volumes occurs automatically, successfully washing out the metabolic CO2 and maintaining a nearly normal level…

How to Calculate a Scuba Weight Belt


Reprinted from eHow

Diver wearing hard weight belt.

Diver wearing hard weight belt.

The amount of weight required to safely descend at the start of a dive and to maintain a safety stop at the end of a dive is not limited to what is installed on a weight belt. Proper weighting depends on many variables such as exposure suit type and thickness, tank composition and diver experience, in addition to body weight. For a streamlined profile, weight can and should be distributed so the diver can establish an efficient position in the water. Distributing weight among the weight belt, BCD, ankles and/or tank can offset pressure in one area, thereby increasing comfort.

Instructions::

Calculate Diving Weight
1
Multiply your weight by 10 percent to calculate the amount of weight to carry when you’re diving in salt water wearing a 3mm wet suit with an aluminum tank (80 cubic feet). For example: 150 pounds x 0.10 = 15 pounds
2
Add one pound for each additional millimeter (mm) of thickness if your wet suit is thicker than 3mm. For example: 7mm wet suit is 4mm thicker than 3mm, so four pounds is added to the calculation in step one.
15 pounds + 4 pounds = 19 pounds
Subtract four pounds if you’re diving in fresh water, such as in a lake. For example:
Freshwater wearing 3mm wet suit (150 pounds): 15 pounds – 4 pounds = 11 pounds
Freshwater wearing 7mm wet suit (160 pounds): 19 pounds – 4 pounds = 15 pounds
4
Round up (i.e., add a pound or a few) so that you can evenly distribute weight or if your fat-to-muscle ratio is greater.
5
Evenly distribute the weights in your weight belt pouches so that the right and left sides carry equal weight. Consider distributing weight around your body to reduce the amount of weight on your hips.
For example, wear a pair of two-pound ankle weights to reduce the weight belt load by four pounds; weight can also be installed in your BCD weight pouches or pockets.
6
Don the weight belt and check that the weight distribution and length are comfortable. Adjust the weights and the belt length accordingly if desired.

Weight Check
7
Check that you are properly weighted before your dive by donning your scuba gear with a near-empty tank (80 cubic feet aluminum tank containing 500 psi).
8
Enter the water and float on the surface of the water. Place your regulator in your mouth and hold still (i.e., no kicking, sculling or moving).
9
Hold your low-inflator hose and raise it high vertically. Press the deflate button to completely deflate your BCD while inhaling deeply and holding your breath.
10
Check that you are sinking momentarily. If you end up floating at eye level, your weight is fine; if you are floating higher, add two to four pounds of weight; if you descend so that the water surface is above your head, remove at least two pounds of weight.

Review :: ScubaMax Integra 2 BCD


ScubaMax Intrega II available @ kirkscubagear

ScubaMax Intrega 2 available @ kirkscubagear

As an avid diver I was excited to get my kids involved in the sport, but really did not want to have to shell out a small fortune for gear, and of course I wanted to make sure that the gear was reliable.

I scuba dive, love the sport with a Zeagle Ranger BCD, but was not too sure how long my kids would stay committed, so I really could not see spending too much for BCD’s for them. I did not want to buy used equipment for safety concerns. I was at an impasse of sorts then I found the ScubaMax Integra 2 BCD’s at kirkscubagear.

I purchased 2 size mediums for my kids, and honestly wish I would have purchased a 3rd for myself. The suits are well made, with lots of D-rings so that you can hang stuff from the BCD, and has nice big pockets which are great for holding your dive accessories. The plastic tank mount is also integrated into the suit.

They fit is spot on and the kids love them.

These suits are an excellent option. If you are considering renting used or even purchasing used you should consider these BCD’s before you make your choice. As an avid diver, safety is always in the forefront of my thinking especially when it comes to my kids so having the peace of mind that they are safe in great equipment really has given me peace of mind when I take them out. The ScubaMax Integra II is a great product from ScubaMax. I can not say enough positive things about these BCD’s. I really did not expect to be find quality gear in my price range. This is quality affordable scuba gear!

I would honestly say this is one of the best purchases I made in a long time. Delivery took about 2 weeks from the time I ordered and that worked out perfectly. Overall this has been a great experience and I hope my kids take to the sport and continue to show enthusiasm.

In the future I plan on getting all my scuba gear from kirkscubagear, because the price is right and the quality is exactly what I want!

Thanks to George W. for his review of the ScubaMax Integra 2. This is a honest review, from a kirkscubagear customer.

FIELD OF VIEW
Optimizing your field of view, both horizontally and vertically, is the primary goal of a good mask. But having a good downward view is of particular importance. After all, downward is where you’ll find your gauges, buckles, D-rings, BC pockets, weight ditch handles and just about everything else you’re going to want to grab. The better your downward view, the easier it is to see and to access your gear.

It may not seem like a crucial piece of life-support gear for scuba diving, but your dive mask is important. Need help finding a well-made mask that’s perfect for you? ScubaLab explains five features you should understand when shopping for your next window on the underwater world.

Low Volume

Low volume masks are nice because they require less breath to clear. They also create less drag when cruising through the water column, and they tend to provide a wider field of view because the front lenses sit closer to your eyes.
