So this comment here doesn't make you crinkle your nose just a bit?

Sir, your comment's ugliness is exceed only by that of your Avatar...
"a wiff of a troll... " hmm... wtf does that mean? As far as your take on this, as was said above I never said I did not like Rebreathers, just the opposite for that matter, and I knew quite well as to what it would be like. Furthermore I like the dive very much once I got used to the counterlungs, etc... considering it was my first time I did quite well (not my words, instructors). However, the isolation of the ADV valve was never mentioned to me nor did I personally check it as most of the checkout was done by the instructor himself, though we did go over the unit. My point being that for any dive, be it a TRYOUT, it is necessary for instructors to be much clearer on the expectations and equipemnt points.
Again, Evolution is by far not the "rebreather of rebreathers" and as an open minded person that I am, I am interested in trying out other units and from my personal perspective and requirements am leaning towards Optima/Meg... which I am planning on trying shortly..

Hello,

It definitely takes a bit of time before you get comfortable with a Rebreather and get it git and adjusted correctly. A few dives prior to instruction can help you get a basic understanding of how it feels, but becoming familiar with it takes longer.

My first CCR dives were almost scary. After the first pool session I was fortunate to have a unstructured, but supervised, pool session where I took my time and got things adjusted, fit, and figured out. I was able to work on various skills and experiment. It was a world of difference.

If things are not fit correctly it is very hard to get to various controls. If not adjusted correctly the ADV may not fire and buoyancy and WOB can be affected. Until I was familiar with the unit almost nothing is where I visualize it to be (the lungs ride higher than I thought, BCD hose is likewise higher, the OPV was where I though the manual addition was, confusing O2 vs. dilluent addition valves). Overall you need a few dives to figure it all out.

Buoyancy is definitely different. When I dive OC and switch back to CCR I have to get reacquainted with buoyancy again. Time will probably help that.

I would hold off being worried about how things like the DSV and BC work -- how it works doesn't matter nearly as much as becoming used to how it works. A few dives and most of the controls become intuitive. A few more dives and they become second nature. Virtually all the commercially available units , and their BCs and DSVs, have proven to work well in the real world. Like most dive equipment, ,any things can be changed after you buy it to fit your personal desires.

A BOV is nice and can be added.

How could you make a statement like that? How could you be leaning toward any particular unit when you have not tried it. Have you seen the other units? I like the Meg and Optima too but the simple fact is all are competent units and I would have little concern diving anyone of them over 100 meters (if properly trained on the unit).

I love it when people favor a unit because they read a few posts. Don't be swayed by what you read. Get educated. Got to DEMA or another big dive show. See them all and make a smart decision.

Wow,ok here is my 2 cents,love the o2tima have about 50 hours on it,tried the Meg nice unit,tried a few others nice too, Have over 400 hours on the drager dolphin, wish I could have more time on the other units, some day maybe. Its like buying a car, lots of models just need to find the right one for now.

I do have to say I was dissappointed with most G. Cayman diving ops them included since they have that "here is the water go dive attitude..." (perhaps that is how it should be but I find that most other islands diving is much cheaper AND most dive boats really take care of you - ie sometimes its nice for someone to offer you the weights, change your tank, etc.... )


I've never experienced a dive boat crew that did not assist you, did you do something to upset them?


CCR mouthpices are not like OC. you have to play around with them to get them set up the way you like it. Although saying that I put a Golem BOV on my unit and I find the mouthpice much better.

let us know how you get on with the other units you try.

Theo,

Welcome to the dark side then! I look forward to even better pictures, once you have mastered the Meg.

Finally some colour coming into Sydney Rebreather diving, with all the YBODs here, is was getting quite boring.

Cheerio from rainy Sydney (to rainy Sydney).

I love the arrogance, that's how people die ... hmm I have read a number of articles and books and this discussion is NOT an elucidation on my rebreather knowledge but rather me sharing my thoughts on the evolution.... now you should reread my original message since I don't think you really read it but just the remarks... I liked the rebreather fine, what I did not like were few specific things... this is how you find out which unit is right for you... if you look through the forum (and I HAVE) many people had similar comments on the harness, MANY mentioned that BOV should be mandatory and others did compare WOB of Evo to Optima... but that is beside the point... and I am not in the same boat, most people had their trials in a POOL... I had mine in 70 fsw... and it was a fine mini-wall dive at that. So please don't assume and don't point me as to what needs to be read, I am expressing my opinion on THIS specific rebreather (ie Evo) and not on rebreathers in general. I knew quite well as to what to expect, and I also carefully reviewed ALL the diagrams of most of the units in production and knew what I am in for.

robinzon

Was I scared? more like taken aback... perhaps the instructor should of pointed out to me beforehand that the ADV was isolated. I missed none of the all too short briefing that was there. Go figure maybe next time I will get someone who will REALLY go over the unit with me.

My apologies, sorry about that, I thought you needed assistance and looking for advice.

I have removed my posting.

Good Luck with it!!!!!!
