OSTC Sport2



The new generation OSTC sport has a larger display and very long battery life.

With one 1.5V battery, the new OSTC sport runs for 100 hours in diving mode despite the bright colour display and up to 150 hours with a 3.6V battery.

The new OSTC sport has a 20% larger display. It is permanently illuminated and offers a razor-sharp display which can be read at a glance.  This is a real comfort when diving in a dark waters or inside a wreck.

With Nitrox up to 100 % and three gases, the OSTC sport can also be used for staged decompression dives.  An upgrade to a fully-fledged Trimix computer is also possible.

The OSTC sport is completely developed and produced in Germany. It is the result of many years of experience and continuous improvement.

Decompression calculations are provided courtesy of the classic Bühlmann model (ZHL-16c) or gradient factors can be enabled.  Alternatively, the decompresson calculations can be turned off completely with the apnea gauge mode.

The OSTC Sport comes with free firmware updates, an active interactive user forum and comprehensive after sales support, backed by a two year hardware warranty.
