In response to demand for a gas integrated dive computer the OSTC 2 TR has been released with an extremely compact transmitter.

The OSTC TR is based on the proven OSTC 2 and offers the same options and additionally is equipped with a receiver that can receive and display up to five transmitters at once.

The transmitter is extra compact and robust to withstand the toughest conditions and the dive computer displays the tank pressure and the remaining bottom time. The runtime of the transmitter is huge, it runs at least 300 hours in dive mode with only one battery – which can be replaced by the user.

The OSTC 2 TR is a compact dive computer and recharging is wireless using the inductive charging pad supplied.

The OSTC 2 TR 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.

If you choose the sport edition initially, the OSTC 2 TR will stay your companion, even if you want to develop yourself in technical diving, as an upgrade is available to the full trimix dive computer.

Both version offer a wide range of configuration options and additional functions such as an apnea mode or a digital compass. The OSTC 2 operation is intuitive and its big colour display adjusts to the ambient light and is readable anytime, both in sunshine and in a dark lake, and two integrated sensor buttons can be easily used with thick gloves or ring systems.

Developed and produced entirely in Germany, the OSTC 2 TR 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 comprehensive support from both Deep Ideas and Heinrichs Weikamp.
