If you occassionally switch between doubles and singles, you can configure your backplate (including the soft backplates of the TransPac and Nomad) to attach to a single tank by adding two tank straps threaded through the tank strap
slots of the backplates. Note that when a traditional metal backplate is off the tank, the wing will hang loose on on the straps. This is cosmetic and does not otherwise cause problems, but if you wish you can use two plastic assembly screws to hold the wing against the backplate. Omitting the STA also reduces weight.
If you frequently switch between doubles and singles, you may prefer the speed and convenience of adding the straps using an optional single tank adapter mounting plate. Using an STA means the strap buckles never have to be unthreaded and re-weaved plus the STA also holds the wing in place with the plate when off the tank and adds weight to the rig. All modern backplates include provisions for tank strap slots, but if you have an older backplate design without the tank strap slots then you must add straps using a single tank adapter.
We are often asked if the tank mount would be more stable and secure using the STA, as opposed to threading the cam straps directly through the backplate. We've tested several configurations and discovered that threading the straps through the backplate is at least as stable as when using an STA. Using an STA sets the tank farther away from the backplate and allows the tank to rock slightly by pivoting from side to side on the bolts. Using the straps threaded to through the backplate snugs the tank and wing up very tight against the backplate and does not allow the tank to rock.
Tek Tip
Get the Lead Out!
Adding weight is rarely the solution to a trim problem. In many cases, just removing excess weight from the waist belt will reduce the size of the compensating gas bubble and is often a better approach to adjusting trim. However, sometimes the amount of weight is correct but it needs to be redistributed to correct a trim problem, particularly if aluminum cylinders or drysuits are involved. Proceed cautiously and try to remove weight somewhere else when adding a trim weight because in many cases the diver already has too much weight and adding weight, even trim weight, just makes the problems worse.
