Thank you guys, I was thinking that I may have heard something about not being too close. So I just may have just not have read something when I was not paying attention to that since i didn't have one close at all.

i don't have a really large deck area and have the TM already there and the Sonar unit and two places for lights. I have the Nav light socket and also another socket for a remote spot light. Sure will not leave a lot of room to step there, LOL!
