Why buy from Amazon?
Amazon has a documented Prime delivery program that covers millions of items, and that is the most concrete order-related support behind buying here.
Worth knowing
Some customers report slower replies or needing more follow-up than expected when they asked for help after ordering. If an order needs post-purchase support, that part of the experience is not always smooth.
Some customers also report delivery problems after ordering. That keeps follow-up and delivery as the areas to watch if you place the order here.

DIVEIN's take
Why buy from House of Scuba?
House of Scuba publishes a defined return process for eligible items, including when credit or a refund applies and where fees or exclusions can affect the outcome. If you want the retailer's own terms in place before ordering, that is the most concrete reason to buy here.
It also states a continental U.S. free-shipping offer with exclusions, so the order terms are not left entirely to guesswork. That does not guarantee every item qualifies, but the policy itself is part of the buying case.
Worth knowing
Some customers describe friction around returns or refunds, and some also report slower replies or needing extra follow-up when they asked for help after ordering. Read the return terms closely before placing the order, especially the condition, packaging, and fee limits that can change the result.

Quick Facts About Mares 2.0 Transmitter

- Retained compatibility: Mares Sirius
- Wireless tank-information transmission
- Colored LED surface-status check
- Permanent pairing described
- User-replaceable 14250 battery
Other divers also looked at
Surface indication
A quick status check alongside computer data
The colored LED is described for a surface tank check. Keep that indication separate from the numerical information and setup procedure on a compatible Sirius computer.
A Mares tank module with a surface-status LED
The Mares LED Tank Transmitter Module 2.0 sends tank information to a compatible dive computer. The retained selected listing specifically names the Mares Sirius. A colored LED provides a quick tank-status indication at the surface.
Match the exact computer
The model 2.0 designation matters when comparing transmitters. The source explicitly pairs this module with Sirius, but that does not establish compatibility with every Mares computer or another brand’s wireless system. Check the current compatibility and setup instructions for your exact computer before ordering.
The retailer describes permanent pairing. Learn how the module is identified and paired to the computer you will use, rather than relying on the presence of a nearby wireless signal.
Use the LED for its stated purpose
The colored light is described as a quick surface check. It is not a replacement for a numerical tank-pressure reading or a documented gas-management procedure. The retained source does not establish exact LED thresholds, so this page does not assign a pressure value to each color.
Battery and installation
The listed battery type is 14250 and it is user replaceable. Check the current specified cell and the battery-change, sealing and inspection procedure rather than choosing a battery solely because its dimensions appear similar.
The retailer lists EN250:2014 certification to 300 bar. That is a source-stated equipment specification, not a universal compatibility statement or a dive-depth rating. Confirm the installation and complete regulator arrangement with the appropriate instructions.
Compare the standalone Module 2.0 transmitter with other standalone offers. The selected evidence does not establish that a Sirius computer or a complete regulator system is included.
