* Safe Working Load (SWL) sometimes stated as the Normal Working Load (NWL), is the maximum safe
force that a piece of equipment, lifting device or accessory can exert to lift, suspend, or lower, a given mass
without fear of breaking.
WARNING:
The ASCENT-AR2 pressure case and seal have a
static depth rating of
500 meters
(730
psi). Physical shocks to the receiver, such as bumping into a solid object, when it is at any depth can
result in a considerably higher pressure on the casing than just the depth pressure and water may enter the
ASCENT-AR case. If the O-rings or their mating surfaces are dirty or damaged, then water may also enter
the receiver case. If you are suspicious that water has entered the receiver, then follow the suggestions in
the Appendix for troubleshooting a pressurized case.
