External ballast belt for DPVs that enables quick trimming without opening the DPV body. It is useful for divers who travel between waters of different salinity, fit extra equipment to the DPV, or instructors demonstrating different trim configurations.

The belt can also be staged on a line—for example when changing water salinity during sea-entry cave dives.

• For DPV Ø160 mm: 2 × 65 g and 2 × 200 g ballast weights
• For DPV Ø208 mm: 5 × 200 g ballast weights
