I have one of these cameras. Actually it's my second. The first was replaced by Sealife due to a defect. This one also appears to have a problem. I am able to occasionally get really good pictures. Then there are others that have a lot of graininess and you can see small red and green dots. This was only happening in the pictures at first. Videos always came out fine. I have now had videos show up with the same graniness and colored dots. Has anyone else had this go on? I have been talking to a Sealife tech. What he has told me appears to work when I get a good picture. However, the camera will all of a sudden start taking bad pictures. All the pictures and videos have been in a pool. Have any of you had a problem with low powered batteries causing poor pictures? Also what batteries do you suggest. I have tried Duracell and Energizer but they seam to die fast. All help is appreciated.
