DTS Gas Guru

Every mix, from air to pure O2. Nitrox, Trimix and CCR diluents with live MOD, density and fill cost, worked to the PO2 and density limits you set.

The DTS Gas Guru is a professional technical diving tool built for CCR and open circuit divers.

Designed for real-world diving, Gas Guru delivers fast and accurate calculations for Best Mix, MOD, END, EAD, gas density, and gas mixing — all in one clean, reliable interface.

Whether you're planning deep trimix dives, analysing gas mixes, or checking safe operating limits, Gas Guru helps you make confident decisions underwater, built on the same dive-physics engine that powers DTS Dive To Survive.
