Scuba Heat is a heat-exchanging coil that warms the air from your first stage before it reaches your second stage. It mounts on the tank band between the two stages, where the surrounding water warms the air passing through the coil. Atomic Aquatics designed it to protect a second stage from freezing and free flow in very cold water.
Main features
- No moving parts, no batteries and no heating elements.
- Coil made of a thermally conductive, corrosion-resistant copper nickel alloy that does not reduce air flow.
- Fits most conventional single hose regulators.
- Warmer breathing gas helps reduce the effects of cold stress on the diver.
