Questions & Answers

STEVEN M : Does this transmitter use FCC ID MH8A frequency?darrick c : Hello Steve, for that you would need to contact the manufacture (AquaLung) directly for that information.
TIM H : Will this work with shearwater perdix2?darrick c : Hello Timothy, no, the Perdix 2 take the new Shearwater transmitter. This would not work with the Shearwater computer.
JOSEPH S : Looking to pair with the i770r. This transmitter will only work for nitrox mixes? So do I need 2 different transmitters? One for diving nitrox and a different transmitter when diving air?Mario C : this will work for air dives (aka nitrox 21) up to nitrox 40% if you dive mixes from 41 to 100% O2 you need the oxygen clean version. UDRT02
Shopper : I have this transmitter already and paired to a i770R computer . Can I buy a second transmitter for my back up reg and use it for my same computer ?Mario C : Thank you all : ) page 39 of manual: <a href="http://www.aqualung.com/global/technical_library/i770R_owners_manual_EN.pdf" target="_blank">http://www.aqualung.com/global/technical_library/i770R_owners_manual_EN.pdf</a> The i770R can use up to 4 transmitters to monitor gas supplies. The TMT Menu allows for the programming of the wrist unit to receive the signals from selected Aqua Lung transmitters. See the Dive Mode Features section (p. 34) for further information on transmitters. You can scroll up or down to select the TMT (transmitter) you want to modify. The transmitters have the option of ON, OFF, or SET. The SET option will allow you to enter the serial number/ID code for the transmitter. When a transmitter is set ON the message SEARCHING will flash while your i770R establishes a connection to the selected transmitter. The transmitter status will display battery and gas pressure status. If your i770R can't connect to the selected transmitter for any reason, the message NOT AVAIL (not available) will be displayed. NOTE: If the TMT is set OFF for the active gas, the section of the Main Screen that normally displays pressure will be blank. NOTE: If the proceeding transmitter in the menu is set to OFF the settings for the following transmitters will be blocked. For example, access to TMT 2 settings will be blocked if TMT 1 is set to OFF. Hope it helpsMartin S : Yes, it will support multiple transmittersMartin S : You sure can, it will support several transmitters.
Jh J : Can you return a transmitter that was purchased in used, like new condition?Mario C : all products follow our return policy unless specified on your purchase. <a href="https://www.leisurepro.com/i/returnpolicy?OrigTerm=return+merchandise&searchredirect=true" target="_blank">https://www.leisurepro.com/i/returnpolicy?OrigTerm=return+merchandise&searchredirect=true</a>

Stopped Working Aqualung offered NO help

It worked for about 2 years then stopped. I brought it into a local dive shop that services aqua lung. They tested the transmitter and my computer and determined it was the transmitter that stopped working. The dive shop reached out to Aqua Lung multiple times to try and determine if there was a part that could be replaced or anything that AL would be willing to do to help outside of the warranty but AL was unwilling to offer any assistance. Since it was past the warranty Aqualung said there was nothing they could do. Wouldnt even offer me a discount to purchase a new one. My dive shop thought this was very unfair so they offered me a discount to buy a new one. Love my dive shop and their service. VERY disappointed in Aqualung not guaranteeing their product and offering NO help when their product just stopped working.

Aqualung i770R DC/Transmitter

I'm very happy with the Aqualung i770R DC/Transmitter. I just got back from a 6day dive trip to the keys where I finished up my Nitrox training. Got in 2 dives a day, 8 dives, 2 deep dives, 3 on Nitrox. One thing I hadn't plained on was my older regulator didn't have another high pressure fitting for the transmitter. So I now have a new regulator as well. Still learning how to down load and save my dives in the DiveLog app. Already plaining for my next training trip and getting another new rating.

Solid connection

This is my first wireless transmitter, so take my word for what you will. I use a i450T was able keep a signal with my gear off for a solid 3 feet radius which i think is pretty good. It’s pretty accurate too every breath I took would reduce in air pressure so I’m able to gauge how heavy I’m breathing.i haven’t had any problems with this transmitter but I do still have a mechanical pressure gauge attached as backup in case this fails.

It Works

I bought this to go with a i750 initially but didn't like that computer very much. I bought the Perdex AI and it works great with that. It was a little touch and go with the i750.
