I bought an Apollo Bio Dry back in December, and I have to say that I absolutely love this suit. My experience with dry suits is probably a little limited, (5 suits total, mostly used and low end), and about 100-200 dry dives.
Because I always hated diving drysuits, I would suffer the cold in my O'Neil J-suit, (wetsuit), beginning in about May and not going dry again until November. To me drysuits always seemed very constrictive, slow and draggy, and a pain to vent, not to mention all the extra lead they required. I've had an old Harveys Neoprene suit, another older neoprene suit of unknown manufacture, a Mobby's Armor Shell tri-lam and a Hydroglove. I pretty much hated all of them, with the exception of the Hydroglove, which was more of a novelty than a serious piece of dive gear.
The Apollo on the other hand, I feel is about as close to behaving like a wetsuit as I have experienced. First off, it's sleek and flexible. Maybe not quite as sleek and flexible as a wetsuit, but it's close and after finishing a 70 minute dive in Puget Sound to 70' in January, I was still reasonably warm. It made my Mobby's tri-lam seem like a straight jacket attached to an anchor in comparison.
The next thing that I really came to like about it was something that I hadn't even wanted: the ankle valves. I figured these were just a gimmick, as I've done lots of dry dives and never felt threatened by a feet first ascent. Sure, sometimes your feet get a little buoyant, but any experienced diver knows how to right him/herself and vent the air. The thing is, the ankle valves allow you to dive without hardly ever thinking about venting your suit. You just add a little air whenever you feel a squeeze and let the valves vent it for you. It removes one more little bit of task loading and makes the suit dive even more like a wetsuit. There's hardly any air bubble to manage, since in any position but lying on your left side the extra air just vents out.
That wrist valve comes in handy as well. It makes it easier to get the extra air out. On my third dive with this suit, I had added an extra layer to my undergarments and ended up a little underweighted. Because of this I found myself carrying a rock at the end of my dive. I thought I had vented most of the air in the suit as I was upright and couldn't see any bubbles coming out my shoulder valve, but when I lifted my arm up over my head, I watched another stream of bubbles exit, allowing me to drop my rock.
I like the seals too. They're very soft, flexible and warm. No leaks so far either.
I wish I'd bought this suit years ago.
