My wife and I each bought Geo 2.0 computers three years ago. We had a dive trip this past January. When we pulled out our computers my wife's Geo showed no display. My watch was fine and operated fine, never replaced the battery in 3 years. Before our dive trip last January we replaced both batteries. I looked at my wife's watch this week and it prompts me to replace the battery after only 3 months and 15 dives. My watch is fine. Has anyone else experienced poor battery performance with the Geo 2.0? Thanks!!!
