Depth finders give an angler the ability to "see" what is in the water underneath him. The depth finders of old simply told an angler how deep the water was. Modern depth finders provide him with more information, such as bottom composition and fish depth beneath the transducer. A depth finder must have a properly installed transducer for it to work. A transducer is the device that sends out and receives sound in the water. This sound is then interpreted and displayed on the screen. Humminbird transducers are installed in the same way that all other brands are.
Things You'll Need
- Drill with 5/32-inch bit
- Mounting kit (provided by manufacturer)
- Silicone based caulk
- Transducer with cable (provided by manufacturer)
Examine the back of your boat (stern) to determine where to place your transducer. Proper transducer placement is critical for your fish finder. You must mount the transducer in a place that is about a foot and a half from the main motor, will not be smashed by one of the bunks of your trailer, is in the water, and is free from disturbance from the strakes on the bottom of your boat.
Place the mounting bracket provided by the manufacturer up against the spot that you decided on in Step 1. Ensure that your mounting bracket is going to be straight up and down and level when it is secured. Use your level to ensure that you do this step correctly. Also ensure that the center line of your transducer is going to run through the bottom of your boat.
Make a mark on your boat through the screw holes on your mounting bracket with your pencil. Take the mounting bracket off of the stern of your boat after you have marked all of the holes and drill your pilot holes using a 5/32 drill.
Place the mounting bracket up against the stern and align the holes. Twist the screws that came in the mounting kit into each of the holes to secure the mounting bracket. Apply silicone based caulk to each screw to prevent leaking. Secure the transducer to the mounting bracket.
Tips & Warnings
- After you have mounted the transducer, determine if it is level. If it is not, you will need to remove it and start over at Step 2.
