The handwheel indicates at a glance if the valve is open, closed or in between. The Vindicator is an easy way to reassure yourself and show fellow divers the status of your cylinder valve. Dive boat operators and instructors like them because they can see the client tank valve is fully OPEN at a glance. This knob is also oversized, making it popular as a retrofit for valves that are difficult to reach or for use with gloves. In particular we like the idea of using the Vindicator on the crossbar, because isolator valves are notorious for being closed and not getting checked as part of predive preparations and fill operations. Available in four colors: Black, Green (often used to denote Oxygen and very rich Nitrox deco mixes), Green with Yellow band (often used to denote sport Nitrox) and Beige (often used to denote Trimix).

NOTE FOR IN-LINE VALVES: There is NO Vindicator model that will work with the typical "Compact" in-line rebreather valves from APD, Blue Steel, or DGX because the valve stem is too short. However, our full size DGX Premium O2 In-line valve WILL accept a #3 model Vindicator Knob.

NOTE FOR BLUE STEEL and HOLLIS VALVES: You may choose any # knob but you must also select the #1 Insert from the drop down menu to make that knob compatible for the Hollis brand, or the #6 Insert from the drop down menu to make that knob compatible for the Blue Steel brand.

It's easy to install the Vindicator yourself or you can order all the valves sold by Dive Gear Express with the Vindicator already installed. Watch the one minute Product Video above demonstrating installation of the Vindicator on a tank valve.
