Product Information
The Mares Genius Computer Black/Black with LED Tank Module is a versatile scuba diving computer designed for demanding divers. It manages Trimix and Nitrox dives with gas changes and uses data from up to five high-pressure probes to optimize bottom times and decompression. The color, scratch-resistant display is easy to read underwater, and the device can recalculate decompression times when gas changes occur. It supports a predictive multi-gas function and includes a built-in compass, with optional air integration and a rechargeable battery for ongoing diving sessions.
The LED Tank Module provides real-time tank pressure data with a color-coded LED system to quickly assess gas levels on the surface or during a dive. It is EN250 certified to 300 bar and uses a user-replaceable CR123 battery. The transmitter communicates with the main computer to deliver hose-less pressure display and gas-level indicators, helping divers manage gas supply safely during scuba trips.
- Computer features — ZH-L16C algorithm with Gradient Factors and Predictive Multi-Gas Functions; supports up to 5 selectable gases; depth display to 492' (150 m); altitude compensation (manual) and multiple operating modes including Air, Nitrox, Trimix, and Gauge; 2.7" color LCD with adjustable backlight; memory for 1,000+ hours; imperial/metric display; rechargeable lithium-ion battery; upgradable firmware; audible/visual alarms.
- Gas and dive management — Nitrox 21–99% O2, Trimix support; up to 5 mixtures managed with gas changes; auto-recalculation of decompression when gas mixes change; data logging for dive planning and review.
- Pressure and transmitter — pressure display up to 4350 psi (300 bar) on the computer; transmitter range 0–5000 psi (0–350 bar); 7/16" threaded HP port; hose-less pressure display; LED indicators for gas levels (green/yellow/red) and visual signaling during dives; CR123A battery (user replaceable).
- LED Tank Module — real-time tank pressure data linked to the dive computer; color-coded LED for quick surface gas checks and in-water gas level estimation; supports computer/probe pairing for integrated gas monitoring.
- Display and usability — 2.7" color LCD with brightness adjustment; time, date, and temperature readouts; imperial/metric display; manual altitude compensation; audible and visual alarms for safety during scuba and diving activities.
- Compatibility and power — rechargeable battery for long diving sessions; optional interfaces and smartphone connectivity for data transfer and log keeping; suitable for a broad range of scuba gear and diving gear setups.

Frequently Asked Questions
Why do I need my own dive computer?
A dive computer tracks the actual depth and time profile you have dived and the tissue loading that follows from it, which is personal to you. A rented computer has no record of your recent diving, and swapping models each trip means relearning the display and menus when you should be focused on the dive. Owning one you know well is a genuine safety and comfort improvement.
Can two divers share one dive computer?
No. A computer only tracks the profile of the diver actually wearing it, and even buddies who stay together do not follow identical depth and time profiles. Every diver needs their own computer, and passing one between divers or between dives is unsafe.
What does conservatism mean on a dive computer?
Conservatism settings make the computer's calculations more cautious, shortening allowed bottom times and adding margin beyond the base algorithm. Divers commonly add conservatism for factors such as cold, hard work, fatigue, or repetitive multi-day diving. How and when to adjust it is covered by your training and your computer's manual, so set it before you get in the water and follow what your computer tells you during the dive.
What kind of battery does a dive computer use?
Broadly there are two types: user-replaceable batteries, often a coin cell that you or a shop swap along with resealing an o-ring, and sealed rechargeable batteries that charge from a cable or dock. Neither is universally better, as replaceable cells are convenient on remote trips while rechargeables avoid ever opening the case. Follow the manual exactly for any battery change, because an improperly seated o-ring or case is the usual cause of a flooded computer.
Do I need to do anything special for altitude diving or flying after diving?
Yes, both change the picture, and both are governed by your training agency's guidance and your computer's instructions rather than any casual rule of thumb. Many computers have an altitude setting that must be configured before diving at elevation, and most display a no-fly or surface-interval countdown after a dive. Follow your computer and your training, and ask a dive professional or a dive-medicine specialist if you are unsure.
How do I care for a dive computer?
Rinse it in fresh water after every dive day, paying attention to the buttons and around any sensor openings where salt crystals form, and let it dry fully before storing. Keep it out of prolonged direct sun and extreme heat, and avoid pressing buttons while sand is on the case. Inspect the strap or bungee often, because a failed strap loses far more computers than a failed computer does.
What is the difference between wrist, console, and air-integrated dive computers?
A wrist computer is worn like a watch and read by raising your arm, while a console computer sits at the end of a hose with your other gauges. Air integration means the computer also displays cylinder pressure, either through a hose or from a wireless transmitter on the first stage, and often estimates remaining gas time. All of them run a decompression algorithm, so the real difference is where you read the information and how much of it you get.
