Go to your local big box hardware
store and buy an $8.00 angle finder. If the hull
angle is within the range of a 20degree tilt transducer than your golden.
Here are the transducer tilt angles based on deadrise...
16 - 24 degrees = 20 degree tilt
8 - 15 degrees = 12 degree tilt
0 - 7 degrees = 0 degree tilt
The transducer should be placed so that the widest beam clears the keel
. The B60 has a 50kHz beamwidth of 45 degree .
If the boat
is out of the water
you can pick a location and measure 22.5 degrees toward the keel
and see if the beam hits the keel.
Or if the boat
is in the water
you can place the transducer in a sealed bag full of water and connect it to the plotter. Then place it where ever you would like to put the transducer and check for proper operation. Make sure it is properly oriented.
Or let a professional take care of it.
Read the Airmar installation manual
for more information. Seriously read it.
