it sure sounded irregular once the unit was submerged. Ninety per cent of the time you did not have a 'relatively' stable continuous threshhold tone but rather the tone would continuously go all over the range of sounds. I was able to hear a few targets though over these other sounds. Is this normal??? Awfully annoying! and I'm sure you would miss targets.
Was in waist deep surf and it seemed like when a wave rolled over, the unit would act up more. Holding the coil steadily as close to the bottom as possible did not seem to stabilize the threshold tone. Had the sensitivity set to auto, discrimination to accept all. Had the coil cover off so as not to load up with sand cuz I've read that can be an issue. Battery was fully charged. As I moved into shallower water, and the control pod came out of the water, the threshold tone would stabilize. Would appreciate any comments about this. Thanks....
