Open Source Trimix Dive Computer 2n (OSTC 2n)
The OSTC is a robust, easy to use dive computer. It's designed to accomodate any changes in your diving, whatever you decide to do.
The bright, easy to read screen remains, increasing in size to a 2.4" OLED display that is readable in all light conditions without having to press any buttons.
The OSTC is rapidly gaining popularity in Europe. The low cost, combined with modern screen technology and free upgradable software makes it a viable option for many divers.
The OSTC is an Open Source dive computer. This means that the hardware schematics and software is available for everyone to view, and if you are so inclined, modify. The software is constantly being reviewed, updated and tested to add extra functionality to the unit. This is available to all users at no extra cost.
All OSTC's come loaded with the latest approved release of the software. It uses Gradient Factors to calculate decompression. These are user definable to adapt the decompression profile to suit you and your diving. Other standard hardware features include:
There are many customisable functions including the rate to sample depth, warning settings, Gradient factor settings and so on. For a full list please refer to the Online manual as these are upgraded as new software features become available.
The OSTC can currently be used in 6 different modes.
Dive profiles can be downloaded using the appropriate software. The OSTC 2n connects directly to your computer and does not require a hub.
Some of the software features of the latest firmware are below:
JDiveLog is an Open Source Logbook with the capability to download OSTC profiles. It can also be used to upgrade your OSTC software. It is Mac and PC compatible.
Diving Log 4.0 is a PC compatible software program with the capability of downloading OSTC profiles. It can be installed as a Shareware version that allows a maximum of 10 dives to be stored, or it can be upgraded to the full version.
Please note: The OSTC 2n does NOT have the Fischer connector so it cannot be linked to Oxygen cells. The new DR5 is designed for this purpose.
Please note, this computer is a platform for divers who have an understanding of decompression theory and who believe in transparency in the decompression algorithms being used. As with all software, the stable version supplied with the OSTC may have bugs. Remember - always have a back-up for decompression calculations.
