Led 2.0 Transmitter 

The LED Tank Module 2.0 is a tank pressure transmitter that sends data regarding tank pressure directly to compatible Mares dive computers.

Once it has been associated with a dive computer, they remain permanently paired. This characteristic makes pairing quick and easy in the future.

The module omits a signal via LED, and thanks to its color it allows you to immediately understand the quantity of gas in the tank.

This instrument allows you to relax more on dives. More demanding divers, who dive with decompression gas, can also see the quantity of stage gas.

The module's battery can easily be changed and lasts 150 dives.

Its characteristics make this module a fundamental element for photographers and videographers who can easily see their remaining gas.

Technical features:

• Transmits tank information
• Includes a colored LED for quick tank checking on the surface
• Permanent pairing
• EN250:2014 certified to 300bar
• Battery type: 14250, user replaceable
• Battery life: 150+ dives
• Pairs with the Sirius (414145)
