The Guardian Ergotrim scuba diving BCD, with the new Airtrim 2.0 system, allows the diver to easily inflate and deflate their jacket no matter what their position in the water. There is also the possibility of adding an optional Color Kit to the Guardian Ergotrim. Available in 4 colors, it will allow you to personalize your BCD, and also includes a useful line cutter with both a ceramic and a titanium blade.
