Product Information
The LED Tank Module allows you to transmit tank pressure directly to your Mares dive computer. Through a colour code, it is possible to see an immediate estimate of the level of gas present in a cylinder. Once mounted on your first stage, on one of the high pressure outlets (7/16") it can be associated with your computer in no time.
Through a colour coded LED it can be used as a pressure gauge, even when on the surface. The probe has a flashing LED that indicates gas pressure using three colours: green for over 180 bar, yellow at 100 bar and red below 50 bar. Through the use of the LED Tank Module the dive computer is able to provide you with the real consumption in litres once the cylinder volumes have been set, thus optimising bottom time according to decompression gas supply.
To prevent excessive battery consumption through flashing, if there is no change of more than 1 bar for more than 4 minutes, the flashing is deactivated.
The battery is a CR123A and allows between 150 and 200 dives, taking into account operating temperatures.

Frequently Asked Questions
Which dive computers work with the Mares LED Transmitter Tank Module?
It pairs only with four specific Mares dive computers: the Genius (414139), Quad Air (414169), Smart Air (414138), and Icon HD Net Ready (414121). It is not compatible with other Mares dive computer models, so confirm your computer model before purchasing.
Can the LED Transmitter Tank Module be re-paired to a different dive computer?
No. Once the module is associated with a Mares dive computer, the pairing is permanent. This means the module is matched to that specific computer and cannot later be switched to pair with a different unit.
What battery does the Mares LED Transmitter Tank Module use and how long does it last?
It uses a single CR123A battery that the diver can replace. Battery life is rated for approximately 150 to 200 dives before the battery needs to be swapped out, depending on use.
What pressure rating and certification does this transmitter have?
The Mares LED Transmitter Tank Module is certified EN250:2014 and rated to 300 bar, which covers standard scuba cylinder pressures.
