bio-tank lock 10x more tightening torque
Apollo’s tank rentention system for use with any bcd
Installation on your personal or rental bcd
Remove your current strap and buckle from harness
of bcd. You will need to use the strap provided with
your tank lock to insure proper fit and function.
Turn the knob body of tank lock to loosen assembly
and allow easier removal of strap from Buckle side A.
Install system with knob facing the side you prefer.
Thread the included tank belt through your harness
using same method as original strap. Then re-thread
strap thru buckle assembly in order indicated by
numbered drawing at right.
CAUTION Adjust the tank belt to be equal length on both sides of buckles A and B. After threading, the end of belt should
be inside and touching the tank when installed. If threaded incorrectly with ends of belt on the outside instead of inside
against the tank, the belt can slip out from buckle.
Adjusting the belt for various tank sizes
Remove system from tank before attempting to adjust belt.
Fully soak the belt in water to allow strap expansion.
Loosen the knob assembly for maximum separation of buckles A
and B. If this does not allow sufficient space to slide over top of
tank then you will need to adjust threading. Using a consistent
tank size will reduce the need to adjust tank belt.
Adjust strap to same diameter of current tank in use.
1. Hold Buckle A firmly and push the belt out as shown.
2. Adjust the length by pulling on one side of belt as shown.
