The compact and robust aluminium housing of the OSTC3 is suitable for depths up to 120 metres and incorporates a 3D compass. The OSTC3 is operated by the firmware hwOS which offers a wide range of configuration options and additional functions such as an apnea mode. The OSTC3 supports Trimix and allows to pre-set up to five gases for a given dive. Decompression stops are calculated using either the classic Buhlmann model or gradient factors. Rebreather divers may monitor their oxygen levels with an optical interface.
The high-contrast colour display can be read even by sunshine and in darkness. It is saved by a Perlucor® ceramic panel which is very solid and pressure-tight. Benefiting from a simple power concept the OSTC3 works with an easily replaceable AA battery. The internal logbook records up to 1000 hours of diving and is complemented by a variety of logbook software for all computer operating systems.
