Piranha PTB Module Weighting

  • Updated

The Piranha comes weighted and balanced from the factory for neutral buoyancy in fresh water. For saltwater use, install the provided weight plates. The weight plates come weighted for the brackish water of the Pacific Northwest region. For use in saltier water, such as the Red Sea or Mediterranean, add the black weight tabs supplied in your spares kit to ensure proper buoyancy.
