Has any divers experienced their Galieo-Luna computer not going into the 3-minute "safety-stop" at 15 ft...I have contacted Scubapro regards to my computer not showing a safety stop and they said to hover at 15 ft. for 30 seconds, then it will activate the counter...I tried this several times and for a whole minute and nothing happened...any thoughts, recommendations...Scubapro wants me to send it back for a check-out, and I'm thinking that will eat up a good portion of my summer by the time they recieve it, analyze it, then send it back out to me...
