Humminbird HDR 650 Trial Installation, Positioning the Transducer and Preferred Mounting Area

Page 30

2. Trial Installation

You will not be able to adjust the mounting after an inside the hull transducer is installed. It is best, therefore, to perform a trial installation first that includes running the boat at variousspeeds, in order to determine the best mountingarea before permanentlymounting the transducer.

1.Plug the transducer into the depth sounder, then power up the depth sounder. When the depth sounder detects a functioning transducer, it will automatically enter Normal operating mode.

Preferred Mounting Area

2.View the sonar signal at its best by holding the transducer over the side, immersed in the water, so that it is pointing straight down over a known flat bottom. Use the display to benchmark against the sonar signal that will be detected once the transducer is placed in the hull.

3.Place the transducer body face down at the identified mounting location inside the hull, with the pointed end towards the bow (see the illustrations
