Heinrichs Weikamp OSTC plus

The OSTC plus fulfills the needs of sport divers and tech divers equally.

It always feels good to have further options. With the OSTC plus you have all opportunities. It can be operated both with the firmware hwOS sport edition for sport divers and the firmware hwOS tech edition for technical divers. If you choose the sport edition initially, the OSTC plus will stay your companion even if you want to develop yourself in technical diving. For a fee you can get an update and upgrade your OSTC plus into a full trimix dive computer.

The tech edition covers all ranges of technical diving including trimix and rebreather diving. The sport edition supports nitrox diving with three gases and is a reliable companion even for challenging dives. Both fimwares offer a wide range of configuration options and additional functions such as an apnea mode or a digital compass.
The OSTC plus can be operated easily and intuitively, its big colour display adjusts to the ambient light and is readable anytime, both in sunshine and in a dark lake. Two integrated sensor buttons can be easily used with thick gloves or ring systems

Developed and produced entirely in Germany, the OSTC plus is backed by years of experience and continuous improvements. Last but not least, it comes with free firmware updates, an interactive user forum, rapid service and competent support.
