Anybody else having an issue with having to run the Leaktracker on HIGH to scan most pools?? Fresh batteries in both units and a new probe a few months ago. I very seldom ever used this setting before. I had to use it a few days ago in a 24 foot above ground that had no other grounds other than the skimmer faceplate. Prior to that it was in a few ingrounds and on medium power the device showed me nothing. I had to switch to high and be within a few inches of the opening. It is a pain to have to return to a job due to a possible issue with the device not functioning properly.
