Galileo Luna Air Pressure Transmitter

[RGP]

G'Day. Is the Galileo Luna transmitter always "on" (with battery installed) or does it turn off when no air pressure is detected or after period of unused time? Do I need to remove battery when it is to be stored for a time to save the battery? I installed a fresh battery two months ago, and it is now depleted.

On my Galileo Sol the transmitter turns off when the pressure is removed. My transmitter battery has lasted for about two years now. I believe there are multiple transmitters for the Sol/Luna though, with the latest having an led that changes colors as the air pressure goes down. Mine uses a coin cell. I think there is another version with a larger battery (and better signal), and then the latest with the led.

Cool..thanks for the info. I do not have an LED. Im guessing, then, that this was a bad battery (the larger version). Ill give it another go. Cheers!

I have the older transmitter with the larger battery and no LED. I had to replace the battery after a year with 40 dives. Now, 6 months later I have to replace it again. There was no warning on the computer! It would take a minute or two to establish a connection on the surface but would lose the connection in the water. Why is this thing eating batteries?

The only way to answer that question is to send it in to Scubapro for service. They may have an answer or they may offer you a replacement. Either way, that is pretty much your only consumer type option. Good Luck and don't expect to get an answer from them as they have pretty much abandoned their monitoring of this site.

The older Scubapro transmitters indeed eat batteries. I replace mine every six months routinely. I just ordered a bunch of the batteries off eBay, and keep them in the fridge. I don't know if the new transmitters (with the LED) are any better, but you won't get a good answer from Scubapro. It just is what it is. They last 1/4 of the time that the Luna computer itself lasts. But they work well and I just accept that I have to replace batteries regularly. That means you should also lay in a supply of the orings.

That o-ring is a 26mm ID x 2.0mm C/S
You can use buna/nitrile, EPDM or Viton with a touch of silicone or Christolube grease.
