Description
The Mares Grace Ergotrim BCD is a versatile scuba diving buoyancy control device designed for stable trim and comfortable buoyancy management during dives. It integrates Airtrim 2.0 technology with an ergonomic layout and a pneumatic inflation and deflation system for smooth, responsive control in a range of diving positions.
Ergotrim technology enables buoyancy adjustments in any position, while the Ergo command can function as a traditional inflator for teaching and as Airtrim when stored in its dedicated holder. The aircell is separated from the shoulders to reduce pressure and enhance comfort, and the high-lift aircell with winglets supports reliable buoyancy control. The Monoplate backpack accommodates single or double tanks, and the system includes 50 mm swivel buckles plus stainless steel D-rings for durability and secure setup.
