O2ptima divers who want a fast method for sensor calibration without having to fill the loop can now use our Calibration Caps. They help to conserve gas with small cylinders. We came up with a calibration cap set that consists of an inlet cap with a BC hose connection to plug your manual oxygen hose into and an exhaust cap fitted with a mushroom valve so you can evacuate the canister and fill it with oxygen for calibration. Since it is a mushroom valve you can’t overpressurize the canister while calibrating. It’s simple to use and carry with you. DRT-27-CAL We’ll post pics in a day or two.

Also, the Quick Release buckles for the 1.5 inch cam straps are in-stock. You can add them to any of the 1.5” cam straps on the O2ptima tanks or a stage bottle. We used to use these same buckles for independent doubles on 2” cam straps years ago. No more having to reweave the cam buckle. BC2036-QR .

We’ve added a 60 micron filter to the solenoid inlet on the O2ptima. This should help keep the solenoid from getting any debris in it when disconnecting the oxygen hose. I just finished six hours of CCR time with the filter in place. We need to modify your solenoid inlet to accept the filter. Call or email service at service@diverite.com to send your head in if you want us to install the filter.
