Humminbird 1197C SI Fish Finder User Manual


 
NOTE: The integral temperature probe will not work with in-hull mounting, so you may either want to consider
purchasing a Temperature/Speed accessory, a Temp. Sensor, or obtaining a different transducer. Humminbird®
offers a transducer exchange program to swap the NEW and UNASSEMBLED transducer, accompanied by
mounting hardware, for one without an integral temperature probe. Call the Humminbird® Customer Resource
Center at 1-800-633-1468 for details, or visit www.humminbird.com for more information.
NOTE: Your transducer may not look exactly like the transducer shown in the illustrations, but it will mount
in exactly the same way.
• Locate transducer mounting location
• Perform a trial installation
• Route the transducer cable
• Permanently mount the transducer.
1. Determine the transducer mounting location
Decide where to install the transducer on the inside of the hull. Consider the following to find the best
location:
Observe the outside of the boat hull to find the areas that are mostly free from turbulent water.
Avoid ribs, strakes and other protrusions, as these create turbulence.
As a general rule, the faster the boat can travel, the further aft and closer to the centerline of the
hull the transducer has to be located in order to remain in contact with the water at high speeds.
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 various speeds, in order to
determine the best mounting area before permanently mounting the transducer.
1. Plug the transducer into the control head, then power up the control head. When the control
head detects a functioning transducer, it will automatically enter Normal operating mode.
