OSTC Nitrox to Trimix Software Upgrade




The OSTC 2 and OSTC Plus can be operated both with the firmware hwOS Sport edition and the firmware hwOS Tech edition.  The Tech edition covers all ranges of technical diving including trimix and rebreather diving whilst the Sport edition supports nitrox diving with three gases.

The sport edition initially can be upgraded to the full trimix dive computer.

The upgrade firmware pack is required from Heinrichs Weikamp.  This unlocks the computer an enable Tech firmware to be installed.  

The unlocking software is specific to the serial number of the computer so the serial number must be supplied at the time of order.

Before placing the order it is advised you confirm you have the correct software installed on your PC to apply the upgrade when it is supplied.
