This is a mixed set. The first stages are Hollis DC3 DIN first stages and the rest is all Diverite.
The XT left hand regulator provides the perfect hose routing for the left tank paired with our 84-inch hose and a right angle adapter. The hose no longer has to wrap around the neck where it can catch; instead the hose runs under the arm straight to the mouth using the angle adapter. The XT right hand regulator pairs with a 22-inch hose for the right hand bottle, again with an angle adapter to avoid pulling.
