How do i "AIM" my fish finder transducer head when mounting it to my boat.?
I dont know exactly how these tings work to understand best how to mount them.
The unit I have looks similar to the unit in this picture i found on google here:
http://02e1dde.netsolhost.com/blog1/wp-content/upl...
It has a back side that is flat (as shown in the picture) and a front rounded side (in the picture is facing forward on the boat and not visible.
The new one i bought, looks similar to the one that came off the boat so i think they are commonly made in this shape and design.
My problem is that the current mount location risks it striking the prop if it is turned too far, so i was consiering rotating it 180 degrees so it mounts facing the back of the boat instead of the front, but im not sure what that will do.
How do these units emit their sonar or radar energy. I know radar transceivers emit a 30' beam, but im not sure how these work.
If its mounted as it is in the picture, is the beam going straight down? If so i dont feel like it would hurt if i rotated it the opposite way.
Basically im trying to ask how these things emit their signal so that i can best understand how to mount it and if its goign to work if i rotate it 180 degrees using the same mount

the reason for the "boat" shape is to aid getting a smooth flow of water over the face of the transducer. Any entrained air bubbles will severely affect the reading. Turning it around will probably lead to turbulent flow & poor readings. Simply move it a bit further out to the side of the transom away from the prop's arc.

Go to the website of the manufacturer of your transducer- there will be mounting instructions for your model. The basics are the same for all transducers:
- it should be mounted as far away from the propeller as is practical (water turbulence effects the accuracy)
- it should be mounted parallel (level) with the water when the boat is stationary in the water.
Here's an example:

Well, you could just try it.
The beam comes out the bottom, yes, with maybe a 40 degree spread.
Mine, I stuck it to the inside of the GRP hull with grease at about 30 degrees on a sailboat and it works OK down to about 200 feet, depending on the bottom type.
