Lamar English developed this slick modification
It basically modifies the ADV with the addition of a standard BC inflator male QR post. This provides another way to input offboard diluent, or the removal of the manual add valve on exhale counterlung should you want to streamline your rig, reduce clutter, or minimize failure points (Hogarthian rebreather configuration
). It also allows you to easily strip your rig down if you run your hoses low-profile and thru the wing.
The following images detail the modification. Just follow the steps to make the modification. All fittings have already been loosened and the shots are just for illustrative purposes...
1. ADV with Apeks shutoff.
2. ADV with threaded fitting.
