A lot has changed since the 1970's when North Florida sidemount cave divers were modifying jacket BC's and building their own homemade sidemount rig. These early sidemount systems worked all right when diving smaller steel 72 or aluminum 80 tanks, but did not have enough lift for larger tanks. Today, the Nomad Expedition Rig has 50 pounds/23kg of lift, allowing divers to dive steel 95's, 104's and 120's using a wet suit or a dry suit. Divers are using the Nomad not only for cave diving, but also to create a low-profile rig by sidemounting stage bottles and for bailout bottles on rebreathers. The Nomad wing provides excellent streamlining by integrating the TransPac harness through wing keepers that hold the wing low across the diver's back and reduces drag. Proper trim is achieved with a longer wing and a Gusset Control System (GCS) cord that is woven through tabs on the front face of the wing. The GCS cord is positioned on the upper portion of the wing, forcing the lower part of the wing to inflate preferentially, keeping lift around the divers hips where it is needed. Tough, ballistic nylon outer bag protects the wing from tears and abrasion. The 15-mil urethane bladder is abrasion resistant, chemical resistant and resists the growth of microorganisms. Choice of Dual bladder wing (BC3100P-DUAL) or single bladder wing. Choice of 16-inch or 12-inch elbow corrugated hose along with either 15-inch, 22-inch or 27-inch low-pressure inflation hose. Utilizing the TransPac harness, tanks are attached with a bungee and butt plate system that allows the tanks to ride closely at the diver's side, yet not jammed under the arms, which can cause "A-framing" when backing out of tight restrictions. Tank bungees are available in 15-inch length for petite divers, 17-inch standard length for most all divers and 19-inch for very large, broad-chested divers. A standard 2-inch crotch strap is included. Cam straps, XL bolt snaps and shock cord complete the system and are used for creating primary attachment points on sidemount tanks. The Nomad Wing is designed for use with the TransPac. Made in the U.S.A.
