What is a fish finder?

A fish finder is referred to as an echo sounder specifically made to reveal the presence of fishes in the water. This device is also capable of measuring the entire depth of the water. A fish finder makes use of the technology of echo-reflection to reflect electronic pulses off fish and various underwater inhabitants, and transforms this information into a graphic representation, which usually come in the form of a HD format or liquid crystal display format. The image displayed on the screen which depicts individual fish with a little icon or as a collection of archs, helps the fisherman to spot the best targets and informs them of the range in which their baits or lure should be lowered to.


This device works by sending an electrical signal which is transformed into a sound wave by a device known as a transducer or a hydrophone stationed on the underside of the hull and thrown into the water. When the sound wave hits something like a fish, it is sent back and shows the size, shape, and composition of the fish. The precision of the result is dependant on the frequency and the power of the pulse sent. The signal is then amplified and transferred to the display unit which graphically depicts the distance to the fish.

While the boat is on transit, the fish finder’s display will enable you to actually see what your eyes can’t see. You’ll be able get a view of the fishes present underneath, their location, size, and other underwater inhabitants.

By going through these mounting locations, you’ll be able to determine which is the best mounting location for your fish finder.

When mounting your fish finder, what you are actually mounting or installing is the transducer. This can be affixed through your hull, in your hull, on the transom, or probably in a side mount.

Through the Hull Mount

Several professionals and novice prefer mounting their fish finder through the Hull mount. This mount location consists of meticulously carving a hole in the boat’s bottom and mounting the transducer in the hole, so that it is directly in contact with the water.

Since the transducer is affixed to the end of the hull, the reflecting echos and ultrasonic signals are quite clear. However, most boat or kayak owners are cautious of this method because it could cause leakage if not properly done. If you are to mount your fish finder using this method, it should be done by a professional.

In Hull mount

Mounting your fish finder or transducer in the hull is a little different from the “through the hull” mounting position. Rather than mounting the transducer in a hole created in the hull, it should be secured with silicon in a well-designed case. Oil is placed in the case to ensure that the transducer is always in contact with the hull of the boat. Selecting an ideal mounting position is important, elsewise, water turbulent and air from underneath the boat might result in interference.

This method helps to solve the issue of hull leaks, but it has its disadvantages. It’s not compatible with, wood, aluminum, or other materials that take in an enormous amount of sound waves. Because you mounted it against the hull rather than the water, you will observe a 20% to 50% decrease in accuracy and sensitivity of your fish finder.

Transcom mount

This mounting position is normally used in little boats. The transom is situated at the back of the boat. This position is to a far extent the easiest position to mount your fish finder, but it also has it’s disadvantage.

The drawback is that, there is a noise generated by the aeration of the water by the motors.

Side mount

This method of mounting your fish finder is ideal for anglers who don’t want to adopt the hull mount position. Rather than permanent mount, the transducer is placed on a lengthy pole affixed to the side of the boat. When going to your fishing spot, the pole is lifted out of the water, when you get to your fishing destination, the mast is lowered till the transducer is immersed.

This method or position of mounting your fish finder provides you with the best quality of the in-hull Installation, with reduced noise without the risk of making a hole in your hull.
