MP,

I checked the location of the foam transducer pad in my Bell Magic and I have it placed almost to the end of my bow.  It is outside of the diamond shaped foam core that you said is in a Bell Magic. Now I get why my shoot thru the hull set up works in my Bell.

I peeked into the inside of my Wenonah MN II and it looks as though Wenonah does not use a diamond shaped foam core layout like Bell does. The foam core in the MN II covers a real big area of the bottom of the canoe. There appears to be a very small area that is free of the foam core that is in front end of the bow just behind the skid plate I installed.  I will give that location a try to install my foam pad for the transducer.
