The GENIUS Scuba Dive Computer from Mares is a versatile tool for diving with Trimix and Nitrox, supporting gas changes and integrated gas supply management. It accepts data from up to five high‑pressure probes and uses the ZH-L16C decompression algorithm with Gradient Factor for optimized ascent, including predictive multigas calculations across up to five selectable gases.

The full‑color 2.7” LCD is scratch‑resistant and paired with easy‑to‑reach controls. It delivers hoseless tank data from up to five transmitters with color‑coded pressure readouts for quick readability. In scuba and gauge modes, it supports Nitrox (21–99% O2) and Trimix (hypoxic or normoxic), with a maximum operating depth of 150 m. Altitude compensation is manual, and alarms can be set to audio or video. A rechargeable 18650 Li‑ion polymer battery provides about 40 hours of dive time per charge and up to 500 recharge cycles, with 1000 hours of memory at 5‑second sampling. An optional interface expands connectivity, making it a robust choice for diving gear setups.
