To whom it make concern, please consider me a “stroke” for this day forward. :)

About 7 years ago, I got into Tech Diving/Cave diving. I remember it vividly because my psycho-ex-wife tried to throw all my dive gear away the day before I started taking my nitrox course. I quickly got hooked up with DIR/GUE and progressed thru Cave 2, Tech 2 and other courses.

Let me say that I’m interested in all diving equipment/techniques, be it DIR, monkey diving, cave diving ,wreck diving or rebreather diving and I frankly don’t believe the GUE mindset of rebreathers killing you if you so much as touch one. Also, I’m a geek, no’f said

I was always interesting in rebreathers but thought they were voodoo. Something that didn’t have a mission in my diving. However, I kept my eye on them and recently thought that the risks were far outweighed by the benefits of them.

Basically, my dives were deep and for “big dives” I was humping a heavy set of doubles and a bunch of stages for one dive. Also, I starting to do exploration dives where you really don’t know where you might end of up and need some flexibility. I felt a CCR was a great tool for these requirements, with the added feature that I would be silent to marine life and have a huge gas supply at almost any depth.

I then went thought the selection process which I can only describe as trying to find out which brand of car you like best. Coming from a DIR/HOG mindset, I didn’t want anything on my chest to clutter it up, which only left back mount counter lungs.

Next, I took part in a rebreather experience course and tried both a manual and electronic rebreather. I really liked the manual ccr and didn’t really care for the electronic version, as I felt like I was merely a passenger in a car and I really prefer to drive. During this time I did a bunch of reading, asked a lot of questions and settled on a KISS or a rEvo.

In the end, it came down to cost. I was offered a very good deal on a KISS and that, as they say, was it.

I liked the rebreather experience course that Robin Jacoway of Deepoutdoors, taught and I wanted to train in the area that I would be doing my diving. Deepoutdoors is in Poway, CA which is only 20 mins from my house and we have a plethora of dive spots that are great for training.

Day 1:
The class was Robin’s first KISS class and was team taught with Dan Crowell. There were 3 KISS divers and 1 rEvo student. We went thru the academics, and built our units, it was a long day. But I was like a kid in a candy store, I get to really do something with my rebreather.

Day 2:
Pool rebreather diving. Buoyancy wasn’t bad, DIR slams buoyancy into you, so adjusting to the lack of lung volume affecting my trim wasn’t a big deal, but it did take some time to dial it in. Then it was back to Deepoutdoors to strip, clean and prep our units for the next day. Oh and go through more class room material. Since it was Sunday, Nate and I volunteered to get cylinders filled for the class at the dive shop Nate works at. We loaded up my truck with a gazillion rebreather and bailout bottles and then spent the next 2 hours waiting for the shop manager to get back and open up the shop.

Day 3:
Open water beach diving @ Marine Room. We kicked out to horrible vis and a leaky manifold on my KISS unit, so my dive was only about 30 mins before I had to head in. We had planned on doing two beach dives but Robin scrubbed the second due to the poor conditions. Then it was back to Deepoutdoors to strip, clean and prep our units for the next day. This was also the start my nightly rebuilt project as each night something new would fail the negative test.

Day 4: Open water boat dives. Motored out to the artificial reef, Yukon, off the coast of San Diego. We were practicing our skills a little deeper and did three dives on the Yukon with no major issues. I did have my DSV o-ring go out on the last dive but this happened as we were practicing our bailout ascent so it didn’t ruin the dive but did make it more realistic. Then it was back to Deepoutdoors to strip, clean and prep our units for the next day. Oh and repair my DSV/BOV.

Day 5: Back on the Yukon for out two last dives. These dives were going to be deeper and longer while we practiced our skills and adjusted to the unit. This is the first dive where I really started to pay attention to anything besides my PPO2 and I got real close to all the fish and listened to the the silence. Theses were fun dives and allowed time to fine tune our oxygen addition, minimum loop volume and learning the muscle memory of where everything is on the rig.

Then it was back to Deepoutdoors to take the written tests and then Robin informed us that we passed. We are now manual rebreather operators.

Divesigns, a UK company, has a line of stock and custom stickers for your dive gear. They range from MOD stickers, Rebreather specific decals and custom name decals. They also have a light visible sticker they call “Stealth Stickers” that reveals it’s text when you shine a light over it.

The custom name stickers are cool for marking you dive gear on a busy boat deck or liveaboard.

To divers, traveling on airlines with tons of scuba gear is almost always a pain. Add a rebreather and it can get even more complicated. You have weight issues, extra baggage fees and the fear that something will get broken, stolen or confiscate.

I saw this on San Diego Tech Diving and Rebreather World and it’s an excellent run-down of all the issues.

I work for the airlines in the US, so I will try and throw in my 2 cents.

- TANKS. you can travel with tanks (ill advised) as they can be siezed by TSA without warning and you will not get them back. They must be checked, valves removed, with absolutely nothing blocking the tank opening. They can be asses even about clear packing tape over the opening, or they can be cool. It is anyones guess. Pre-ship or make arrangement at your destination for tanks.

- SORB. Easier to pre-ship. There has been discussion on another forum about putting all of you sorb in a Kitty Litter tub and checking it in as baggage. Probably illegal but who knows. There are MSDS sheets you can print out and attach to your sorb tub. BUT while passengers have followed all of the rules on taking sorb on the plane the TSA has still chosen to confiscate it. You have no recourse for the confiscation, it is gone. Make back-up arrangements at your dive destination for SORB purchase.

- Rebreather. Carry on what you can, the delicate parts, the computers whatever you don’t want the baggage handlers or TSA rooting through (without your presence), possibly stealing or confiscating. Double check the allowed carry-on weight allowance.

- Check you airline website for weight restrictions for both carry on and cheaked baggage. All airlines are different and they change all of the time. Weigh you bags at home and work out the weight distribution before you get to the airport.

- I took my KISS CLASSIC as carry on baggage the last time I travelled, with my computer, DSV, put other parts in my scrubber. Just be prepared to take it all out and show them EVERYTHING.

Sometimes it is just easier to ship everything, with insurance.

I was poking around the interweb and I stumbled upon this SCUBA regulator mouth-piece: The Manta-Bite. Apparently, it’s designed to be placed in your mouth and then the “manta wings” create a water barrier.

This would allow you to relax your bite on the mouth piece and in theory make it more like breathing with your mouth slightly open.

The picture to the right shows how you pinch the mouth piece before you shove it in your mouth. I’ve read of people using these to protect their airway should they passout underwater. The thought is that with this type of mouth piece you wouldn’t lose the regulator as your jaw relaxed.

Maybe it’s comfortable but to me, it looks like it might rub my gums raw, I’d need one to review.

$39.99, available in Clear, Green and Black

I LOVE my iphone but I miss have a scuba diving decompression program on it. Having this I can plan my technical dives on the device that I always on me, my cell phone.

I used to have jdeco on my Blackberry, and before that I had DivePlan on my Sony P800 and way before that Decoplanner on my Palm. But when I moved to the Iphone, I had nothing and I so I had to go back to my PC/Mac based decompression program.

However, on the horizon there is now hope: IphoneDeco.com. The site just went up and announced the development but not yet released version of a decompression program for the Iphone/Ipod Touch platform.

From www.iphonedeco.com:

iPhone Deco works in conjunction with MyDecoPlan.com to bring an interactive, intuitive approach to dive planning for the iPhone. Open Circuit, SCR & CCR Dive Planning With Buhlmann/GF and VPM/B - Coming in June 2008!

MyDecoplan.com will give you a sneak peak on what they thinking. I can’t wait until June.

Bikini Atoll the sight of the famous US hydrogen bomb tests should be some of the more radioactive places on earth. One would expect a vast waste land both above or below the water.

However, this isn’t the case, Bikini’s coral reef is flourishing with life. The coconuts are radioactive as they absorbed the cesium and other particles in the soil but the background radiation in the sea is the same as anywhere else in the world.

You can dive Bikini’s coral reef and it’s nuclear fleet; a set of test ships blown up to see the nuclear affects of a nuclear attack on warships. However, it’s very expensive.
