      Hello Bob
      I use the on sale depth systems, Just use a plastic bag half full of water to find a place where you get good readings. I have two on the starboard side in the middle of the boat. I choose the location for convience some 10 years ago.
      Cheers, JohnDean

      I installed an ST40 "in hull" depth transducer in an Ohlson 38, and more recently an ST60 "in hull" transducer in my Nic 35. Both were installed in the inboard/aft corner of the locker just fwd of the chart table, with the liquid filled tube vertical. Both appeared to work perfectly.
      Best regards
