Author Topic:   Best Fishfinder/Depth Gage-17' Montauk?

A Little Madness posted 07-25-2005 08:19 AM ET (US)
I currently have a Humminbird Fishfinder/Depth Gage with a transducer I've placed in 6 different location on the transom, and it still reads 400+' above 15 mph in the ICW. I give up!!! Both Boston Whaler and Humminbird have said I need to use a thru hull transducer. I don't believe it. Is there anyone out there who's successfully installed and uses a reasonably priced fishfinder/depth gage that maintains its integrity above coasting speed? HELP

I've got a Raymarine unit on a Sakonnet hull installed 10 inches to the right of the centerline per the inlcuded instructions. It works through the boats entire speed range. Only time it loses bottom is during tight left turns when the boat banks over. Is yours to the left of right of the motor? It should be on the right so the prop blades are moving down, away from the transducer face. They can create pressure pulses which can cause interference. BillS

I have an Eagle Fishmark 320 on my 64, 17 footer, and have absolutely no problems at any speed. The transducer is about 24" from the centerline, on the right side. Not sure if it looses bottom on tight left turns, will have to check next time I'm out.

I have a setup similar to bsmotril except that it's a Sakonnet with an inexpensive Humminbird. I followed their directions and it worked perfectly from the get go on anything over 2 feet up to as deep as I've found around here.
I haven't checked the turns but it sounds reasonable, the transducer wouldn't be in solid water.

Had a hummingbird diminsion-3 , 3d. After several mounting positions the "winner" was positioned 2-2.5 time deeper than the instructions said. (about 3/4 of the transducer is below the water line) It throws a mean rooster tail but it works well!

I just installed a Humminbird Matrix 77 on my new Montauk and it seems to work just fine. Mine does kick up quite a rooster tail also.

Could you be a little more specific about location. Port or Starboard, how far from centerline or motor, etc. I get one more try and then my wife has hammer privledges on the unit after it's removed.

Do you wash the transducer with a good detergent. Oil on the surface will prohibit a good water contact to the plastic and give you all sorts odd readings.
P.S. has anyone tried "rain-x" on the transducer? I will be trying it this year. For those that do not know it is a product that somehow 'breaks' the surface tension of the contact between glass (plastic?) and water maintaining a uninterrupted sheet of water. I believe it may eliminate the air bubbles on the surface of the plastic.
