Description

Wether you are a free diver, underwater hunter or just like snorkelling in shallow water, this timer will be useful for you. Both CO2 and O2 training tables are included as well as tables for square and triangle breathing training techniques. Store more oxygen in your blood and cope with higher levels of CO2.
