I also use the luna and have never had a lost signal to my knowledge although I suppose it may have lost and found itself befor I noticed as I do not stare at it while under water. I generally try to check it every few min for about 20 seconds. It'll beep and remind me that I only have (X psi.) Left and need to wined down my dive soon. I do not use a spg. On my primary rig but I do on my pony bottle. Im just not willing to buy a 2nd transmitter for my pony. My button gauge on my pony cost 8 bucks my transmitter cost much more! So I opt for one less hose myself.
