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.

PADI Altitude Specialty Certification, Lake Tahoe

 

Lake Tahoe Dive Site

Lake Tahoe Dive Site

I just finished with a PADI Altitude Specialty Course in Lake Tahoe earlier today. It was a spectacular day at the lake. The water temperature was 64 degrees and we made dives to 50 feet and 30 feet.

The Altitude Specialty Course is valuable to any diver that visits high altitude lakes since the special procedures for diving safely are critical above 1,000 feet in elevation.

Any diver wishing to earn PADI Altitude Specialty Diver certification can contact me (joe@joescuba.com) through Sierra Diving Center, (775) 825-2147.

Alameda Man Killed in Monterey Diving Accident

 

Breakwater in Monterey, CA

Breakwater in Monterey, CA

http://www.montereyherald.com/news/ci_18738019

Another diver lost his life in Monterey last Saturday. This time it was a 65 year old Alameda man who’d “recently gotten back into diving.” According to the story, he and his diving buddy had begun to surface when he simply disappeared. Shorty afterward the search was on and his body recovered about 30 minutes. Autopsy results ruled out a heart attack.

I have no additional information, but my guess is that inexperience played a major role in this tragic accident. The safety record in diving is exceptionally good. As a whole, the diving industry is incredibly safety-conscious and the level of available training, technology, etc. rises everyday.

What the industry can’t control is the individual. Often, we deal with individuals who haven’t been diving for some time. Perhaps someone was an avid diver in the 70′s, but work, family and other pursuits interrupted his or her diving activities. Now retired, that person decides to get back into the water, relying on expertise and a fitness level remembered from a bygone era.

There is no reason a person can’t return to diving after many years. In fact, I encourage it whole-heartedly, but please don’t expect to jump in a swim you did when you were in your 20′s. Get some up to date training. Have your equipment inspected, or better, simply replace it. And, hire a professional to serve as a guide and to bring you up to speed on current safety practices and procedures.

I often say that, as long as everything goes well, diving is a pretty easy activity. Inhale, exhale, repeat. It is impossible to say how many dives should be supervised before going it alone. For some, a simple refresher course is enough. For others, maybe not.

The point is, diving is deceptively simple. For all I know, none of this applies to this diver. He could have been a shining example of fitness and presence of mind and this was just a freak, random event. Statistically speaking, that’s probably not the case. The water off Monterey can be pretty rough. At the very least, it will be cold and the visibility somewhat limited. Every diver must consider his or her experience level and personal ability to deal with issues underwater or on the surface (and level of fitness, please).

My heart goes out to the family and friends of this man. He no doubt left people behind who loved him and will miss him dearly.

Jack’s Diving Locker

Jack's Diving Locker - Dive Boat

Jack's Diving Locker - Dive Boat

Not long ago, I made a post about dive industry people not responding to customer inquiries. Specifically, I named SubGear and Jack’s diving Locker because I had recently attempted to contact both–more than once.

Within a day, I was contacted by Andy Woerner of Jack’s Diving Locker who had seen my post and expressed concern that they had apparently not received my emails. Based on his quick response, I believe that to be true. At the same time, he asked that I restate my questions and explain the method I used to contact them. (I have yet to hear from SubGear)

My original note to Jack’s was related to buoyancy checks. As I suspected, they encourage all divers to do achieve neutral buoyancy prior to their dives, recognizing the shortcomings of surface checks and fin pivots as a means of assessing a diver’s skills overall.

I agree. Surface checks and fin pivots, especially for new divers, really only provide a starting point. Nervous divers tend to breathe at the top of their lung volume, giving the impression that they are underweighted. There are other factors as well.

To give a much better feel for the actual weighting requirements and to refresh a diver’s skills overall, Jack’s offers a pool session for only $25. I can’t recommend such sessions enough. It’s a great way to blow the cobwebs out and get comfortable with the gear, as well as providing an opportunity to get to know the people at Jack’s Diving Locker along with the procedures for making dives later from the boat.

I was really glad to have been contacted by Andy. I love diving with Jack’s Diving Locker and have had many great experiences with them. So, it was disappointing to think they don’t care enough to answer their mail. This December, we’ll be diving with Jack’s for sure!

Eradicating Invasive Lionfish Destroying Caribbean Reefs

Lionfish Warning Sign

Lionfish Warning Sign

Of all the environmental tragedies that I can be upset about, one stands out as unique and potentially more devastating than many that are much more widely publicized. That is invasive species. We are dealing with it locally by trying to prevent the spread of zebra and quaga mussels, similar to what’s happening in the Great Lakes.

In the Caribbean, Lion Fish that have been somehow released from aquariums are making their way into the ecosystem throughout the Bahamas, and as far North as the Carolinas here in the US.

Measures are being taken to rid the region of these voracious predators, and even PADI has introduced a diving specialty certification course focussed on safely reducing their numbers.

As information becomes more available, I’ll be sure to follow up. Hopefully to report on some successes.
