Mike, A couple of things, i ran into an issue with TSA when trying to use carry-on for my tanks (rEvo). TSA decided at the security checkpoint that they were too heavy and required me to check them, and to return to the ticket counter to do so. While they were helpful in some small ways, it...

Congrats Michal, the rEvo is a cool unit, I've test dove it as well. I'll look forward to hearing your new experiences with an RB and the incrediable encounters that typically follow.

Alberto, sounds like you're having fun. A couple things to add to your knowledge base. Extreme Scuba has a RB club allowing certified RB divers a way to not get the full cost of a RB up front. You might give Richard a call and look into it. Another thing that I considered when chosing...

I will do my first REAL dive on a rebreather this Saturday (in a pool) AM After you get over the initial heavy task loading and the OMG what am I doing, you'll find these are really very simple machines and a joy to dive. Hope you take to heart all the checks and protocols. RBs are...

Was that a virtual dive or real? If real where was the dive? And if its your first dive on an RB how about sharing your experience, for me it dramacally changed my future diving, and I knew it immediately upon reaching the reef after decending.

Locally I'm getting 2-3 hour bottom times / day mostly due to the boat I'm on. When on vacation I get 5-7 hrs of bottom time a day depending on the gear I'm using. I cheat, I use a rebreather so its not uncommon for me to just do 2 dives a day, 1 all morning and 1 all afternoon for a total...

Nikon D200 - camera is still better than I am using it. I really love the sharp crisp focus.

While initially, the photo opportunities convinced me to shift to SCR (trial dive), once I began to dive it frequently, the warmth, lack of dry-mouth and longer no-deco times were a welcome benefit. Shortly there after not having to change out tanks between dives was nice. After shifting to...

This questions causes me a bit of concern. Your dolphin course should have given you the formula's to figure this out. But to answer your question, I used an alum 50 cu in tank when getting fills was tough, or if able just changed out the 27/28 cu ft tanks between dives. The oriffice...

I've done two trips, and both were great. I can not say enough good things about this liveaboard. There are several trip reports on the two ships (Bilikiki, Spirit). You might try a search and then I'd happy to answer specific questions. Great diving, great crew, go with friends to get...

As one who also started on a SCR (Dolphin) and has moved onto CCRs, I am not as inclined to blanket recommend that folks go direct to CCR. I think that most of us on CCR are very comfortable doing deco dives, and a fair amount of us dive beyond rec limits. But, that does not mean everyone...

One other consideration is the diameter of the hoses, and the effort required to exhale a full breath; on some units a fair amount of the WOB is just getting the air through the DSV. When you consider the fairly small opening for the mouthpiece, the right angle turn required, and getting past...

Very nice discussion. On the original topic I have a couple things to add I did not notice posted. Since the basic principle of the scrubber is that a CO2 molecule must impact the scrubber material to get a reaction (bonding), The density of the gas passing through the scrubber can/will...

I too have had a lot more "close encounters" with sharks. As I explain to those asking about my RB, the good news is you don't scare away the fish, the bad news is you don't scare away the fish. I've had to up my knowledge of various animals and their behavior patterns to compensate. All...

Ocean Enterprises, had a tent sale recently and I think there are several classes using boats; so you can call them if you're looking to get into a class. For boats the Marissa is top notch. A run to the Coronado Islands for a 3 tank day including night dive, followed by a local to the wrecks...

Haven taken the DSAT & TDI deep air courses, as well as the IANTD normixic & trimix courses; if I had to do it all over again I would still do the DSAT course. Like any course; the quality and performance requirements are highly dependant on the instructor. In the class I did no one was...

Hey All, :wave-smil Our own MissyP has successfully passed her Instructor Exam (IE) and is a newly certified Open Water Instructor. For those who know and can attest to, the IE can be quite challenging and sometimes you get the really tough drills to resolve or little...

Rhone, To address your question with a few numbers. The database I've been compiling has approx 165 deaths when the diver was using or had been on a rebreather. With my first case in the early 1950's. There have been over 600 deaths while Cave diving most of them on OC. Also...

The D200 S&S housing is very milled aluminum verses lexan. It really depends on which strobes you plan to use. if you have not yet purchased them Ikelite strobes are quite nice. I like the fine control the S&S offers, I have direct buttons for most everything the camera offers. Both...

My $0.02 as well. They have 100% for fills, granule sorb available and if you're certified, you can rent an Inspo, Draeger and I think a KISS. Bob & Tina are awesome, they frequently have gone out of their way to help me and my dive buddies.
