Come on people, this thing is geared towards novice as well as true recreational divers, meaning go for a vacation once or twice a year, dive a bit, look at the fishes, don't touch the reef follow the DM kind of diving. For that purpose, I believe there's nothing wrong with it and it does it's job well. This, in the end, is the average scuba diving industry consumer generating revenue for brand name companies.
Not that I'd get or want one, my personal opinion applies to any conventional back inflate or jacket type BC.
I had my choice of all sorts of BC's when I got certified. My dive buddy went tech and got Apeks and Dive Rite equipment. I wanted recreational/photography and ended up with the i3 and Kronos; simplicity.
I will not be entering wrecks nor do I have the desire to descend 200 + feet. There is nothing for me to photograph at those depths as of interest.
I'm diving every weekend with this BC and I really enjoy all it has to offer. It makes me feel safe and confident and I have dialed in my bouyancy much faster than my dive buddy on wings.
This thread should not become my BC is better than yours; this is about exploring options and this is one.
Someone mentioned the lever will get stuck on kelp and it will deploy, that is nonesense the lever deploys itself when adequate pressure is applyed either up or down, I don't see kelp pushing it down or up.
It's amazing how many divers talk about this BC and they have never ever dove one; one reason is that it's too expensive to place as rentals and second no one will dish out the money for something they feel is trivial.
If you are really concerned about kelp and feel the hose is more adequate, you can attach the airsource 2 or 3 and disconnect the i'3. When someone else borrows your BC just disconnect the airsource and place back the i3.
A lot of divers talk about redunancy, this BC would be a good choice if you wanted three back up systems for air off your tank, the octo, the regulator and the airsource.
You also have 5 steel D rings to play with. All in all you have choices and it's up to you to read and educate yourself before you condemn products.
I'm still waiting for the first post that comes up about an accident in scuba based on the i3 technology; hasn't happened, we will see....
