Any unit will breathe like crap if your diluent has not the right gas density as per Mitchell et al. rEvo's have been used on very deep dives e.g. Pearse resurgence etc. as far as 200M with no WOB issues reported publicly that I know off. I've had mine to 135M with no WOB issues either.
It breathes perfectly fine if you are pitched up at a 35 degree angle. I'd contend that if you feel it breathes perfectly fine, you either have terrible trim or haven't compared it to a rebreather that really does breathe perfectly fine. Notice all the pictures you see of people diving revo's are in bad trim? Now you know why.
Partially agree, through user error I flooded mine with say 2 liters of water and nothing happened. Bottom line is, if you use the unit as per manufacturers recommendations i.e.with a gag strap, where can the water get in?
Mine was flooded as part of a manufacture defect inside the loop. It was completely filled. But even if it was user error, mistakes happen, there needs to be a way to resolve them, especially if your 10k feet back in a cave. To specifically answer your question, water can get in from a bad OPV. And that's not where my failure occured. Suffice it to say, there needs to be a way to continue a dive WHEN it DOES HAPPEN.
Completely agree, whats even worse is that RMS is now 7 years in operation and it is still failing with the exact same failure mode. Shame on rEvo. Exactly
if the unit was as bad as you maintain I am wondering how did you manage to sell all four of them for a PROFIT? I don't really want to get anyone in trouble. Lets just say I'm really really good at buying and selling. I buy super super low, and sell for going rate. I've built quite the scuba empire doing that.
