How we calculate scores →About this gear
O’Three’s APV is a balanced drysuit relief valve with a low-profile arrangement and replaceable service parts. It is intended for divers who need a toilet connection during longer drysuit dives, with the appropriate user interface fitted.
Consider before buying
Correct installation, connection and cleaning matter. The valve’s lifetime warranty is limited to the original purchaser and excludes consumables including hose, connector and sheaths. Do not treat the marketing language as a guarantee against leaks or as evidence that the valve prevents decompression illness.
Our take
SCUBA reviewer Neil Hope reported successful use over multiple dives in April 2022, but provided no numeric overall grade. That is useful qualitative evidence, not our own test. Consider APV if the need justifies adding a maintained valve and hose system to your suit; otherwise, the extra fitting and care may be unnecessary.
