OSTC cR

Starting at: £825.00

The OSTC cR adds 3-cell oxygen sensor monitoring to the OSTC platform.

The OSTC cR has a large bright colour LCD IPS LCD screen optically bonded to the front glass offering superb viewing from all angles in dark conditions and direct sunlight.

The hardware schematic of the OSTC cR is available and it is a fully unlocked and open source computer. This means all software upgrades are available at no extra cost.  If you are more technically inclined, you can write your own deco programs.

The OSTC cR runs the same proven software used by the OSTC 2 with decoplanning and simulated dive modes and is rated to 120m.

  • ·       3D compass with tilt-compensation
