My Signet Smartpak depth sounder has a problem that was reported (by "Jim" with a Cat 30) and kicked around a little, but I didn't find a real answer. The problem is that it mostly reads 2.2, and sometimes the actual depth. It started out as intermittent thing (scaring the crap out of me) and progressed to a constant 2.2 reading. Unfortunately, cleaning the bottom/transducer didn't help. Any thoughts? I did call Signet tech support - they suggest I drop $150 for a new transducer to test the old one, but hauling out destroyed my paddlewheel transducer this year (not just the wheel, dang it) so I'm not sure I want to put $150 into a new speed transducer and $150 into a depth transducer when a new Standard Horizon (or Raytheon ST40) whole system is $330. Jim - if you're out there, what did you do?
