ascent control
Do not use your Bc for buoyant ascents during normal diving. This could result in loss of
buoyancy control or a buoyant ascent at a time or speed that could result in injury or death.
Do not use your Bc as an assist or "lift bag" for bringing objects to the surface. These
objects may be lost during the ascent, creating a sudden increase in buoyancy and loss of
buoyancy control.
proper training in swimming, scuBa diving, buoyancy control and emergency buoyancy
skills is required to safely use this product. Successfully complete a course of training in
SCUBA diving, buoyancy control and emergency buoyancy skills from an internationally recognized
educational organization.
By maintaining neutral buoyancy throughout the dive you will not need to add air to start an ascent.
Locate the valve you intend to vent air from prior to ascent. Assume a head up position and begin
kicking to initiate an ascent from a neutrally buoyant condition. As you ascend, the air in the BC will
expand, increasing your buoyancy and rate of ascent. Vent small amounts of air frequently during ascent
to remain neutrally buoyant and control your rate of ascent.
Vent air from the BC before becoming significantly buoyant or exceeding the normal ascent rate. It is
preferable to visually confirm that air is venting from the valve. Continue the ascent with a comfortable,
slow kick.
Make sure that the valve you intend to use for venting air is higher than the air bubble in your BC.
Positioning the valve below the air bubble may prevent the bubble from being vented.
unintended ascent
Should you experience a sudden, unintended increase in buoyancy that might occur from a loss of
weight or free flowing Balanced Power Inflator Valve (PIV), immediately assume an upright position
and vent air from the Manual Dump Valve of the BC, or Oral Inflation Valve. Practice this skill under the
supervision of a certified SCUBA instructor.
2. InItIaL set up
This section instructs you on the procedures required to initially set up your BC. For best performance
and safety, it is recommended that your BC be first configured by a SUBGEAR authorized dealer.
Additional parts or accessories may have detailed instructions not covered in this section or manual.
Read and follow all instructions not covered in this section or manual. Read and follow all instructions
included with parts and accessories you intend to set up on this BC.
Low pressure (Lp) Hose
Current model SUBGEAR regulators have 3/8-24 UNF threaded low pressure ports and 7/16-20
UNF threaded high pressure ports. Some older regulators may have 3/8-24 UNF threads on both
low pressure and high pressure ports. If you are unsure as to which port is low pressure, connect
your underwater pressure gauge to the port, if the threads on the port and hose are compatible.
When pressurized, the low pressure port should not read more than 200 psi (13.8 bar) with a full
SCUBA cylinder. Some modern high performance regulators may have 1/2-20 threads on the low
pressure ports. An adapter may be required to attach the 3/8-24 threaded fitting on the LP Hose to
these ports.
