O2ptima Harness & Wing Recommendation

Recommended harness and wing for the O2ptima rebreather, including Lamar's personal set up.by Lamar Hires

Our 2010 model O2ptima has an aluminum shell and stand with a soft, Rhinotec 600-denier cover. The aluminum shell is designed with 11-inch center spacing to accommodate any technical harness and wing combination desired.

I recommend the TransPac® harness, which is by far the most popular set up. It is lightweight and the soft shoulder straps work well for attaching the counterlungs. It is also to easy to change or move hardware on this harness, something every rebreather will invariably need to do.

A hard plate is functional with the O2ptima and I recommend a stainless steel plate, if additional weight is needed for buoyancy. Most divers will add 4 to 6 lbs of lead when diving the O2ptima rebreather, so a 6 lb steel plate is a good option. Combine the steel plate with a TransPlate harness and you get the same ease of mounting counterlungs and adjustments as you do with the TransPac.

Wing selection is dependent on environment and bailout options. The Rec and the Rec EXP wings are the most popular choices due to their 50 lb lift capacity. The Rec wing has the advantage of being longer and giving buoyancy at the hips. It’s gusset control system is preferred because it can be pulled in for a smaller profile. The Rec EXP is excellent because…

The Nomad has become a popular choice for the O2ptima and other rebreathers. The rig is designed for sidemount and puts buoyancy at the hips, where sidemount and rebreather divers need it most for trim. The Nomad can be limiting in cold water if an argon bottle is worn or if the primary light is mounted on the side of the harness because the wing is tied down and you cannot easily mount items in front of it.
