CCR Upgrade


The NiTek Q can be upgraded at any time to be used with closed circuit rebreathers. Using a constant–P02 setpoint ranging from 0.4 to 1.6, the CCR upgrade allows you to program the NiTek Q with the set point you have programmed into your rebreather. As long as you run the rebreather at the setpoint you programmed into the Q, it will provide accurate dive and decompression information. You can change setpoints on the fly in DIVE mode to account for any shifts you may make on the rebreather.

You will need to program the NiTek Q with your rebreather diluent gas and all bailout gases for each dive. The setpoint is programmed separately and is used to calculate your decompression. If you have to switch from closed circuit (CC) to open circuit (OC) mode during a dive, you will be able to change to your pre-programmed bailout gases to complete any decompression.

NOTE: You must unlock the Trimix upgrade to upgrade to CCR.
