PADI Tec40 Course, Lake Tahoe

PADI Tec40 Course, Lake Tahoe

PADI Tec40 Course, Lake Tahoe

If you’ve ever wondered what it takes to push your diving to the next level, PADI Tec40 is the first step beyond recreational diving. The PADI Tec40 course offers an introduction to diving with redundant systems, double SCUBA cylinders, lift bags, deco bottles and gas mixes up to 50% oxygen.

More importantly, PADI Tec40 takes you into technical decompression diving. Decompression involves making stops at prescribed depths prior to surfacing as a means of ridding your body of nitrogen that would otherwise form bubbles in your tissues.

Technical diving isn’t for everyone, but for those willing to accept the risks, technical diving in Lake Tahoe is an experience like no other.

PADI Deep Adventure Dive, Lake Tahoe

PADI Deep Adventure Dive

PADI Deep Adventure Dive

Any time of year, Lake Tahoe is a great place to dive. We brave the cold water to experience Lake Tahoe’s amazing visibility, and fabulous underwater topography. Many of Tahoe’s dive sites, like the Sailboat in Hurricane Bay are located on drop-offs that reach into extremely deep water.

Diving these site safely requires skills beyond what’s necessary for diving the shallows. For example, narcosis due to elevated nitrogen partial pressures can affect decision-making and judgment. Also buoyancy issues due to greater compression of the diver’s exposure suit, must be dealt with appropriately in order to maintain control.

When you plan your PADI Deep Adventure Dive, consider carefully the colder temperatures. If you’ll be making that dive in a drysuit for the first time, you’ll need to plan a drysuit orientation dive in advance of the deep dive. For this to be possible, the drysuit dive will have to be scheduled on a different day prior to the deep dive in order to avoid a reverse repetitive dive profile.

Diving in Lake Tahoe is a blast. Diving deep in Lake Tahoe can be spectacular. But, be sure to get the proper training and consider the conditions before jumping in and heading for the bottom. For more information, contact me: joe@joescuba.com.

Kona SCUBA Diving Trip 2011

I finally found 5 minutes to upload 30 seconds of video from last month’s Kona dive trip. I’ll eventually find time to put up something a little longer, but if this sequence doesn’t make you wish you were there, I don’t know what it’ll take.

This was, I believe, our 5th dive. We had large numbers of dolphins on the previous dive the day before also. On other dives we had spotted eagle rays, turtles, many large moray eels, the occasional shark and, of course, tons of coral and schooling fish.

The trip was fantastic. It’s really odd to have 80 degree weather and palm trees mixed with Christmas decorations. I’ll be posting more video clips soon.

DUI Dry Gloves, Zip Glove Review

DUI Dry Gloves Review

DUI Dry Gloves Review (Zip Gloves)

Last week, after literally thousands of dives in drysuits, I decided to buy myself a little something for my birthday; dry gloves. Specifically, I bought DUI Zip Gloves in the standard, heavy duty (blue) version. I know DUI was/is changing to black, so mine may have been hanging around the shop a while, but I don’t think so. Nevertheless, I got them into the water the very next day, while taking PADI Open Water students into Lake Tahoe for their first open water dives. First Impression I can’t believe I didn’t switch to dry gloves years ago. Then again, my drysuit (DUI CF200x) was made before ZIP Seals were available, and dry gloves with standard wrist seals are a different beast. Zip Seals are absolutely one of the coolest things in the world. I had my suit converted to Zip Seals by DUI last year when I needed the zipper replaced. Back to the gloves. Once I got them home, I went about the business of attaching them to the suit.

The recommendation is to run the inner seam of the drysuit sleeve about center on the Zip Glove’s palm. I have been twisting my wrist seal around for years into a position that doesn’t put an annoying twist in my sleeve underwater, so I knew that centering the seam wasn’t going to be right. Instead I just held each sleeve in the position I know rides naturally in the water without a twist, and attached the glove with the thumb on top relative to that. The position turned out to be exactly right.

My concern all along with dry gloves was that I’d lose too much of my sense of touch. In reality, that isn’t the case at all. I have been using 5mm neoprene gloves (Fourth Element, and they’re awesome!) for a long time, so I haven’t had much sensitivity anyway. With DUI Zip Gloves, I found that I actually could feel things, and manipulate objects better than with the wet gloves. That may be in part due to my hands being SO MUCH WARMER, but either way, it’s not a factor. Of course warmth is the key. Lake Tahoe was 48 degrees on the surface. Not Arctic, but no tropical paradise by any stretch. Entering the water with your hands remaining dry and cocooned in the fuzzy warmth of the liner is heavenly.

I don’t think I realized before how much warmth I’ve been losing through my hands. Also, since the glove is essentially part of the sleeve, there’s no chance of water seeping in through the channels between your tendons when you make a fist. It’s no joke. With standard wrist seals, I’ve actually gotten into the habit of raising my arm (and foot) out of the water to pull my fins on–just to keep water from running up my arm when I pull the fin strap over my heel. Not any more…

Getting into your drysuit with DUI Zip Gloves Another concern I had was getting into the suit and being able to get my neck seal to lay flat. I’d heard that was an issue. The standard procedure is to get half into the Drysuit like always, then put on a glove liner and pull on the sleeve. Repeat with the other side, then onto the neck seal as always. I found that adjusting the neck seal with dry gloves on is a bit fidgety; mostly because the glove and the seal have bit of a tendency to stick together. And, you can’t feel crap compared to your bare hands. My solution, since I have a front entry drysuit, was to put on my left arm, then go straight to the neck seal. That way, I have a bare right hand to reach up and under the seal to make sure my undies aren’t trapped anywhere, and also, fingers to run around my neck to make sure it’s laying properly against my neck. The trick is to be enough of a contortionist to get your right sleeve on with the neck seal in place. I can do it with very little resistance. My guess is that, that won’t work for everyone. It definitely won’t work with a back-entry drysuit.

Zip Glove Comfort DUI Zip Gloves eliminate anything from constricting around your wrist. It was half an hour after the first dive that I even realized I’d been wearing my watch under the suit. It feels so good not to have that seal, I don’t even know how to describe it. To keep the glove from “puffing” up, there’s a thin Velcro strap that takes up the slack. It does the job perfectly, without the least bit of restriction. So, by now you’ve no doubt realized that I am a huge fan of DUI Dry Gloves. I guess there may be those who feel differently, but especially for very cold water, I never want to dive with wet hands again. Give them a try. I’m pretty sure you’ll agree that it’s the best money you ever spent.

Kona SCUBA Diving Video

The first time I planned a dive trip to Hawaii, I had divers saying things like, “Well, the diving’s not that great in Hawaii,” or “Hawaii doesn’t compare to the Bahamas,” or some such criticism. So, my expectations really weren’t that high. Turns out, these divers either know about places I can only imagine, or they are out of their minds.

Scuba diving in Hawaii is spectacular! I’ll post more video clips that show it, but in a single day of diving, I had encounters with a manta ray (daytime, not the now world-famous manta ray night dive, which is awesome, BTW), several dolphins, a pod of pilot whales, an oceanic white tip shark and the usual dozen or so green sea turtles. I mean, seriously… what does it take to impress some people?!

For those of us on the West coast (U.S.), Hawaii is relatively easy to get to, and actually can be pretty cheap if you book it right. Boat dives are a little overpriced compared to some places, but not that bad, and there’s good access to shore dives in Hawaii, so you can mix it up and do a lot of diving really cheap if you want.

Hawaii also has the added benefit of there being lot’s to do besides diving, so non-diving friends and family can count on a great time as well.

Underwater Pumpkin Carving – SCUBA Diving Patton Beach, Lake Tahoe

This is Sierra Diving Center’s 2011 pumpkin carving dive in Lake Tahoe, CA. The dive took place as October’s fun dive. It is something on an annual tradition. We had about 8 divers ranging from newly certified open water divers to tech divers and instructors. Everyone had a good time. The weather was perfect and the water temperature was about 56 degrees.

PADI Altitude Specialty Course, Lake Tahoe

PADI Altitude Specialty Course

PADI Altitude Specialty Course

SCUBA diving in Lake Tahoe is very popular. The water is clear and generally calm, although it’s a very big lake and can be pretty rough when the weather is bad.

The thing about diving in Lake Tahoe, though, is it lies at a little over 6200 feet in elevation.  That means for the purpose of calculating no-decompression times, we use equivalent depths rather than actual ones. In essence, this means your dive will be treated as being significantly deeper than the depth you actually reach.

As an example, a 100 foot dive in Lake Tahoe is calculated as 129 feet, which you round down to 130 feet, the recreational dive limit. That’s important because the no-decompression limit of 130 feet is very different than for 100. So, if you’re making a dive in Tahoe to 100 feet and approaching the no-decompression limit taken directly from a table (sea level), there’s a very good chance you’ll be taking a ride to the chamber–or worse.

The PADI Altitude Specialty Course covers the fundamentals of planning dives safely at altitudes greater than 1000 feet above sea level. If you’re going to be making those kinds of dives, please take the class. It isn’t difficult to do the calculations and compensate for the reduced atmospheric pressure, but it is essential.

You can arrange a class through Sierra Diving Center, or email me at joe@joescuba.com.

SCUBA Divers Left Behind in Florida

SCUBA Diver Ascending

Scuba divers left behind in Florida

It seems like every other year or so, we read this headline about SCUBA divers somewhere in the world having been left behind by the dive boat. There they are bobbing in the abyss, waiting for someone to motor along and pluck them from Poseidon’s grasp.

It amazes me how a dive boat can actually pull up anchor with fewer people on board than it had arrived with. One might argue that there were many passengers on board, so it was hard to keep track of them all. In that case, I would assume that more than one Divemaster would be keeping track, and besides, haven’t they learned to use a clipboard??

Fortunately, this pair was picked up by another boat captain after about two hours clinging to a buoy, but seriously, I can’t imagine how such a thing could ever happen.

Cold Water Diving Tips

Cold Water Diving

Cold Water SCUBA Diving

For many, Fall means hanging up the swim fins until warmer months next Spring. Sure, you can always take a vacation, but even that leaves an awful long surface interval before the snow melts. With that in mind, let me offer a few tips for making year-round diving not only possible, but fun.

1. Embrace the season. Depending on where you live, the falling temperature usually comes with much better visibility. Forget about the cold for a moment. I am fortunate to be able to dive with people from all over the country–sometimes the world. Very few have a body of water like Lake Tahoe in their back yard, let alone tropical reef systems, so enduring visibility measured in inches is pretty standard.

Over the Winter, algae takes a break, and the green muck you’re used to goes along with it. If you can stay warm, you’ll actually begin looking forward to Winter diving’s great visibility and changing aquatic life.

2. Get a drysuit. If you think about it, the coldest water temperature you could possibly encounter is just above 32 degrees. Dressing for that temperature out of the water is easy. You just bundle up and head outside. A drysuit makes it easy to dress appropriately for any diving conditions.

Drysuits today are available with nearly infinite options, from changeable seals, dry gloves and hoods, different materials, zipper location, you name it. And, when you consider the longevity of the suit (I have over 1200 dives in my DUI CF200 and it still looks new!), the cost of ownership is much lower than diving wet. Most important, you’ll want to dive all the time, and enjoy your dives much more.

A major side benefit to a drysuit is not having to change out of a wet wetsuit in freezing temperatures. You’ll gaze smugly at the rabble of shivering masses and casually stow you gear for the next day’s dives.

3. Take an Ice Diving class. Yep, Ice diving. You’ll not only open the winter months to some truly spectacular diving opportunities, but you will meet like-minded divers and become a much better diver through the additional training.

4. Take any SCUBA class. Use the Winter months to take some diving specialty courses (like PADI Drysuit Diver) and expand your skills prior to warmer weather. If you are interested in technical diving, train now and you’ll be ready for the depths come Spring. Your options are virtually limitless, and you’ll meet new diving buddies who share your interest underwater.

5. Take a diving vacation. As exciting as Winter diving can be, getting away to a warm, tropical island is just the ticket to staying motivated through cold season. Sure, getting out of the cold isn’t exactly a cold water diving “tip,” but that mid-Winter break goes a long way toward keeping us excited about our next trip under the water.

The most important thing is to stay safe and keep diving. Diving in cold water introduces a few variables you don’t experience in warm water, but staying comfortable is a lot easier than you might think. So, don’t hibernate. Get out there and dive!

Top 5 SCUBA Regulators Under $200

Top 5 SCUBA Regulators Under $200

People have been asking me to rate low-priced regulators for a while, so I’ve gathered up a few of my favorites and listed them here. Keep in mind that these or other good, low cost SCUBA regulators are likely to be available at your local dive shop. Please support them.

Here in Reno, Sierra Diving Center has been supporting the local dive community for decades, and has available anything you would find online, along with the expertise to help ensure you make the right purchase. If you live near Reno, please visit Sierra Diving Center before buying any dive gear. Tell them what type of diving you’ll be doing, along with where you’ll be diving, and listen to their advise. Call them at (775) 825-2147.

That said, here are my choices.

Cressi Sub Xs2 /Ac2 Regulator: Buy it now for $159.95

Cressi Sub Xs2 /Ac2 Regulator XS2 is the least expensive regulator Cressi Sub makes. The body of the 2nd stage is standard size,  with a downstream valve system with an adjustable orifice. It is light-weight, simple and extremely reliable. It is also light, which I love.

The 2nd stage also has a flow deviator that acts on the Venturi, with dive/pre-dive function. This helps eliminate free-flow issues prior to going underwater, while ensuring easy breathing during your dive.

The first stage is a piston design, as are all the regulators in this group. Extremely cold water divers might want to look for dry-sealed, diaphragm first stage to minimize the possibility of ice related free-flow. Aside from that, the Cressi Sub Xs2/Ac2 Regulator is awesome for under 160 bucks!

It has 1 high pressure port and 4 low pressure ports, so with a drysuit and an octopus, you’ll use them all. The biggest issue here is that you won’t have a lot of hose routing options, but that’s true for most regulators when you start filling up the ports.

Cressi Sub Ellipse Black Ac2 Regulator: Buy it now for $199.95

Cressi Sub Ellipse Black AC2 Regulator is the step down from the Ellipse Titanium. It “imitates” features of the Ellipse Titanium regulator, but with a casing made from “sophisticated and strong hi-tech polymers.” The regulator features: fold-out opening of the casing, special folding diaphragm, computer designed lever, tilting movement of the poppet, seal between regulator valve and casing. You can remove the entire air supply system from the body of the 2nd stage.

It is a balanced piston first stage, but delivers air smoothly, with little effort. It has enough ports to supply an alternate, plus a dry suit, but hose routing options are limited. As with all regulators listed here except the Genesis GR440, I don’t like the position of the yoke, which points the end of the first stage into the back of your head. Aside from that, you can’t beat it.

Genesis Atlas Gr440 Regulator: Buy it now for 199.95

The Genesis Atlas Gr440 Regulator is my favorite in the group. Largely, this is because of the position of the yoke, which allows for much better hose routing, and doesn’t place a big knob right into the back of your head. Genesis calls it a “high performance regulator,” which could mean a lot of things. What I do know is that Genesis makes very high quality SCUBA equipment, and has been around a long time. That’s true for all of these regulator manufacturers.

There’s a pre-dive/dive switch to minimize free-flow in currents or when entering the water through surf. Genesis also employs what they call the DAD (Dry Air Demand) First Stage. This essentially means that they keep the parts clean and operating reliably by keep the first stage mechanism dry. That eliminates lubricants, which can be messy.

The GR440 is an easy breathing, reliable regulator, with more sensible port positions than the others in the group.

Mares Prestige 12 Regulator: Buy it now for $199.95

Mares Prestige 12 Regulator is my second choice of all the regulators listed in this group. It would be my first if it had teh yoke in the same position as the Genesis GR440. It incorporates all the features that make Mares regulators great. It’s a mid-size regulator, strengthened by the “ultimate technologies” to provide steady, natural and effortless breathing.

I’ve owned a lot of Mares dive equipment over the years and really like everything Mares makes. My complaint about the yoke position is partially mitigated, since it is a relatively compact first stage, and also that there’s a DIN version available. Still the hose routing isn’t nearly as neat as the GR440.

Genesis Yukon Gr320 Regulator: Buy it now for $174.95

Genesis Yukon Gr320 Regulator offers exceptional dependability. It uses ABS/Polycarbonate for the housing, which personally, I like since plastic doesn’t corrode. Some argue that it is more likely to freeze in cold water. In my experience, sometimes that’s true, but can be managed. Diver inhalation effort is preset by the factory so no knobs, dials, you just screw it on and go.

It uses a flow-by piston first stage, which is probably the same as the GR440 first stage, but takes you back to that end-mounted yoke connection. So, for a saving of only $25, I just can’t see choosing the GR320 over the GR440, although it is a good regulator, and worth the price.
