Looks great, fits great, large pockets sls weight system is really good, kinda hard to lock the first time but once it?s in its great. I reall like the fact that you can order an attachement for selfie stick that goes on the underside of the pockets. Really happy with my purchase !

Excellent design features

well designed and functional. I returned a cheaper Tusa BCD for this model which is far superior.

Great BC

I really like this BC. It is very light -- you will notice it right away . since I dive internationally this is a bit plus.. Is very comfortable and easy to get into . Love that the pockets are stretch material vs big and bulky. Lots of nice feature - extra D rigs, knife grommets and hinge straps have completed 7 dives with this BS and love it The only reason I gave this a 4 is the SLS weight system. On my 5th dive I lost a weight pocket mid dive. I had watched demos online and practiced inserting the pockets I have hundreds of dives and this was a very shallow reef dive . Luckily someone in my group found my weight pocket the pocket was in the locked position I had to fiddle with it underwater to unlock it as it would not click in. After fidgeting with it I finally got it re-locked and continued with my dive I was not expecting this and since I am on my way to Bonaire I immediately ordered extra weight pockets Maybe it was a fluke. I like Mares equipment -- it is good quality and as I said I do love the BC

Love this BCD easy to travel with

I live in Michigan and for the most part the water is too cold for me. So I travel to dive, and this BCD travels well, is super comfortable and I find it very easy to establish neutral buoyancy. One of the other things I like is that I am a tall man and this BCD is easy to get into while sitting on the dive boat. Others I have had to get help to get into. Love this product would recommend it to anyone. Rich P

like a lay-z-boy underwater

I've taken the quantum out on 6 dives so far and it's very comfortable for extended wear. The pockets are large and useful and the zippers open and close pretty easily. The material feels strong and the seams are nicely finished. However, It does feel a little bulky if you're trying to get to the bottom metal d-rings while bobbing around at the surface. Overall, it's a great BC and should provide many years of use!
