Apollo has redefined the standards for Scuba diving. The new Bio-Tank Lock can secure a diving tank in seconds with little effort and up to ten times more tightening torque than any conventional tank lock on the market today.

Quick and easy to install on any BCD. Adjustable nylon strap is 33" long to fit standard and extra wide tanks. 10x more torque for a tighter fit; no more struggling to get the strap tight and the buckle clamped down. Spring tension knob extends for easy adjustment; even with heavy glove. Minimal effort; just turn the knob and lock... no more re-threading. With our screw type tightening system, anyone can secure the Bio-Tank Lock with ease.
