I bought a dive computer (Atmos Pro) less than a year ago. When I first bought it, the batteries were dead. I had my diveshop replace the batteries no charge, no problem. No more than 20 dives later, the batteries started dying once again. I know this is not normal, so I brought it back to the diveshop once again. They didn't understand why the computer was eating batteries. They said they would send it away to be checked out. When I brought it in, it was working fine (just like when you bring your car to the mechanic to be diagnosed...haha) I used it one more time because it seemed to be working properly. That dive, the temp was not registering, and I had no depth reading. When I told the dive shop about this, they immediately said they had to send it in. I asked what would happen, and they told me that the computer would most likely be replaced because once the depth sensors go, it becomes a liability to them, and they just replace it. This was 2 months ago. The dive shop finally called me, and told me I had 2 options. First was that they would send me a refurbished computer with a 6 month warranty. Or I could upgrade to the atmos 2, but would have to pay the $275.00 difference. I'm not happy about this. I buy a brand new computer...it's a lemon, and they want to send me a refurbished one? Or, I have to pay for an uprgaded computer? From experiences I've had in the past with other things....if they don't make it anymore, and your item is fubarred, they give you the upgraded model no charge. The atmos pro is no longer available, so this is why they want to upgrade me. If you bought a new car, and 6 months later, it totally dies, do they offer you a same year, but used model? Can anyone help me out here? Who to call, what to do????
