This truly is high end diving with the Atomic BC1. This BC has the most balanced trim and weight system I have ever used. The adjustable tank strap is the most simplest and innovative device I have used for a air source ever. I'am very fortunate have gotten this BC, the one thing I did not like about this BC is that atomic requires you to buy an inflator (even if it's not a second-stage inflator separate) that is immoral in the dive business I cannot name another industry in the business that does this. Chris with Online Scuba included the SS1 inflator with this free of charge and took care of me in this deal. I plan to keep this product for awhile. Thanks team!
