Agir-Brokk has fast become popular among divers (not just techdivers), who want comfortable and perfect trim both swimming and / or on deco. The design itself gives great stability, and prevents front tip over.

Several holes for finding the right trim.
Rubber protection under the zip to avoid impact damages.
