If you love your Transpac but want to start diving doubles, this is the part that gets you there without buying a second rig. The adapter plate mounts between the Transpac and your doubles set and gives you a rigid, stable connection you can trust in the water. Swap between a single tank and doubles as the dive calls for it, and keep the harness you already have dialed in. One harness, more diving. That's a trade we'll take every time.
