WEIGHT INTEGRATION FEATURES
SureLock II™ Integrated Weight Release System
Your BC features the SureLock II Integrated Weight System. With the SureLock II system, weight
pouches are secured with a mechanical locking mechanism. The SureLock II weight system either
supplements or replaces a conventional weight belt. This unique feature allows you to quickly jettison
either one or both weight pouches in the event of an emergency, thereby maintaining better control
over your rate of ascent. The weight pouches can be easily reloaded into the BC pockets while you are
wearing the BC.
NOTE: It is very important to read the following instructions, and become thoroughly familiar
with the correct methods for installing and releasing weight before you dive with your BC.
Maximum Weight Capacity
WARNING: For smaller BC’s, the lift capacity may not exceed the weight pouch carry capacity. The negative
buoyancy of the lead, plus the negative buoyancy of the cylinder (when full), should not exceed the BC’s
positive buoyancy. The inability to achieve positive buoyancy while at depth or on the surface may lead to
a hazardous situation that could lead to serious injury or death. Refer to the model-specific label, usually
found in the pocket of your BC, to find the designated lift capacity, and load weight pouches accordingly
(see photo above).
The SureLock II weight system features two interchangeable weight pouches which can be filled with either
block weights or “soft weight” (pouches containing lead shot), in increments of 5 pounds or less. For ease
of operation, low-profile block weight is strongly recommended. Refer to the BC Weight Capacity Chart for
your specific model of BC for maximum weight pouch capacity.
