• Certified Reliability: EN250:2014 certified to 300 bar, ensuring maximum safety and durability in harsh conditions.

Technical Specifications

Maintenance and Care

To ensure long-term performance and reliability:

• Rinse thoroughly with fresh water after every dive, especially in salt water environments.
• Protect the transmitter from physical impact by using a small high-pressure hose extension if preferred, or a protective cover.
• Check the sealing O-ring regularly for cracks or debris and apply a light coating of oxygen-compatible silicone grease.
• Store in a cool, dry place away from direct sunlight.

FAQ

Can I use this transmitter with other dive computer brands?

The Mares LED Tank Module is specifically designed for use with compatible Mares dive computers (e.g., Genius, Smart Air).

Does the LED flashing consume a lot of battery?

The system is highly efficient. If the pressure remains stable (less than 1 bar change) for more than 4 minutes, the LED stops flashing to conserve power.

Is it suitable for cold water diving?

Yes, it is designed to operate reliably in various temperatures, though battery life may slightly decrease in extreme cold.
