The Twin Balanced piston is sold as an additional accessory for the recreational line of Mares 82X first stages. The TBP is the most innovative alternative for cold water diving kits.
The Twin Balanced Piston provides a fully insulated first stage, ensuring maximum reliability in both freezing water temperatures and extreme depths. This technology is extraordinarily responsive to pressure variations and even meets the requirements of the NORSOK U-101 at a depth of 200 m.
With the innovative 'Pistophragm' technology of the Twin Balanced Piston, Mares offers an incredibly responsive system that works perfectly at any depth and in any water temperature. It is also very easy to assemble and repair. This fully insulated system is the perfect set-up for divers, from those diving in contaminated water situations to adventurous scuba divers under ice.
