Night Diving:
This analogue faceplate is painted with a Japanese-made phosphorescent agent, which glows for hours after exposure to direct light pre-dive. Ideal for night diving and tactical swimboards.
Durability:
The AG-21 diaphragm is the only moving part exposed to seawater. An engineered metal plate diaphragm covered with an outer rubber layer. This engineered design prevents 100% of the most common analogue depth gauge failures; due to prevention of deterioration of accuracy from salt corrosion of the diaphragm.
Wrist strap:
The Apollo wrist strap integrates an adjustment mechanism in the buckle to prevent the depth gauge slipping as the wetsuit compresses with depth.
