Bigblue EO Heat Controller I

Heated undergarments are wonderful — until you are too warm at six meters and cannot do anything about it. The EO Heat Controller I sits in your EO cord line and lets you dial heat up or down mid-dive, so comfort follows you through every depth and stop. Built to Bigblue's salt-water standard for reliable cold-water service. Add it between canister and vest, and take control of your warmth.
