Paddle Wheels and Transducers ?

[DREW FISH]

I posted the same question on the Pro page but I'm anxious. I'm buying a TR-1 and want to put a graph on the back of my boat so when I'm turned around I can keep an eye on the depth and things. Here is my problem,I've got a Bottomlone HR on my bowmount and a Lawrance 350A on my dash. I'm purchacing a X-51 to put on the bow and taking the HR and putting on the back because it has GPS. Therefore I will have the Bottomline transducer and the 350A transducer both on the back of the boat,can I mount these tranducers close to each other and still have them work correctly.If not,why,and how should I go about this. Have never tried it before and really don't want to have interference. Part 2 of my question I can never get a speed reading with my paddlewheels unless I'm trolling 2 1/2 MPH and up. Is this normal or what. I've been using my SOG but would like to resolve this problem, any thoughts.

Paddle wheels need to be cleaned and sprayed with WD-40 to work all the time .
You can use the car wash trick (IF) you are gentle , DO NOT SPRAY LIKE YOU ARE TRYING TO REMOVE BUG GOO .
Hand hold the bottem line transducer off the stern , that will answer your query .
