In my fish finder reviews article many people wonder what is the best place to mount their new fish finder. The is not a perfect position to mount your fish finder. It depends on what type of boat you have and what type of installation you want. However there are 4 fish finder mounting locations you should consider.

This article will help you decide which is the best mounting position for your fish finder.​

4 Of The Best Fish Finder Mounting Locations

When mounting your fish finder, what you are mounting is called the transducer. You can mount the transducer through your hull, in your hull, on the transcom, or in a side mount.

Through The Hull Mount

Many of the pros and avid enthusiast fisherman prefer the through the hull mount. This mount location consists of carefully cutting a hole in the bottom of the boat and mounting the transducer in the hole, so that it is in direct contact with the water. Since the transducer is mounted all the way through the hull, the ultrasonic signals and returning echoes are very clear. However many boat owners are wary of this method because it could lead to a leaky hull if not done properly. This method should probably be done by a professional install technician.

In Hull Mount​

The in hull or shoot through mounting position is slightly different than the through the hull mounting position. Instead of mounting the transducer in a hole drilled in the hull, it is instead just mounted against the hull. It is fastened with silicon in a specially designed case. This case is filled with oil to make sure that the transducer is in always in contact with the boat's hull. It is critical to choose a proper mounting location, otherwise air and water turbulence from below the boat might cause sound interference.

This solves the worry about hull leaks but it has its drawbacks. It does not work with aluminum, wood, or other materials that absorb a lot of sound waves. Because it is mounted against the hull and not in the water, you will experience a 20% to 50% decrease in sensitivity and accuracy of your fish finder.

This mounting position is usually used in smaller boats. The transcom is located at the rear of the boat. This position is by far the easiest position to mount your fish finder but it does have the drawback of the noise produced by the aeration of the water by the inboard or outboard motor.

The side mount is a good option for those that do not want to use an In Hull mount position. Instead of a permanent mount, the transducer is mounted on a long pole mounted to the side of the boat. During travel to and from the fishing area, the pole is raised away from the water. When you arrive at your fishing spot, you lower the pole until the transducer is in the water.
