Re: Fishfinder vs depth sensor
I spent most of the day chasing the transducer wire from the pedestal to near where the old transducer is. While at it, I found a cracked PEX connector for my freshwater system. I no longer wonder why the water pump comes on at night... (now fixed)
Anyway, I tried the Garmin transducer through a bag of water and the hull, and it worked fine. I first tested the unit in my slip, and placed the transducer directly in the water, and it read 7' at low tide. I tested again with the waterbag, and it read 6' 3" (I figure that this spot is about 9" below the water line) I then connected everything up, in preparation to set the transducer in epoxy (I forgot my sandpaper and the attachment for my drill anyway) and lo & behold, the transducer worked without being set in epoxy!
I still plan on setting it in epoxy, but wanted to share for anyone interested that the Garmin echo 200 unit works fine shooting through the hull of my O'day 35.
