Easy to Follow Fish-Finder Buying Guide

A fish finder is a device that locates fish underwater in order to catch some in the largest quantities possible. Also called a sounder, this instrument detects pulses of sound energy, as would a sonar. The graphical display modern fish finders feature allows the user to easily interpret the information and identify areas rampant with fish.

Choosing The Right Fish-Finder For You

Though you may be tempted to choose the most high-tech device with the most advanced features, operating a fish finder that works for you requires you to assess your needs and pick a machine that works in close accordance to them. Sometimes, the more feature-ridden the device, the less efficient it will be in your particular circumstance.

Prior to choosing a machine, you must establish the following:

  • The depth of the water you usually fish in
  • The amount of fish you are looking to catch
  • The volatily of fish-schools in your fishing waters
  • Whether you will navigate between different water depths

Having clear answers to these questions will facilitate the selection process for you. The next step will be to consider the main differing features and elements in different fish finder models.

Transducer frequency

Fish finders have either single, dual or multiple frequency transmitters. The most common frequency levels are:

  • 50 kHz (deep water)
  • 192 kHz (shallow water)
  • 200 kHz (shallow water)
  • 400 kHz (very shallow water)

The higher the frequency of the device, the more detailed the graphics showing up on your screen. As more waves are being sent out and received through the transducer, high-frequency transmitters are the best option for shallow water fishing.

Should you be looking for a luxury high-tech item, you may go for fish-finders with incredibly sharp, 400 kHz transducers. As multiple-frequency transmitters, they have different frequency options catering to different fishing needs in different waters.

Power level

Easy to Follow Fish-Finder Buying GuideThe power of a fish finder is measured in Watts. The greather the wattage, the higher the power of the instrument. This means the readings will be displayed faster, and be usable in deeper water – and vice versa. Were you to fish in shallow water, you’d need relatively low power for satisfactory results.

Screen Resolution

The more pixels your screen can display, the clearer the graphics rendered back to you. It is advised you choose a screen of at minimum 240×160 pixels, for anything under that would show patterns difficult to distinguish.

Cone Angles And Beams

Cone angles establish how wide the beam is sent from your boat to the water bed. The greater the diameter, the bigger the surface your transducer is spanning, and the more information you may receive on your surrounding waters. Large-scale, commercial fishing may require transducers with 40-60 degree angle cones, while 20 degrees is perfectly sufficient for sport fishing.

Transducer Material

Though fish finders come in a range of different materials, most devices come with plastic transom mount transducers. These are compatible with all boats besides pontoons. Plastic housing is the best choice for fiberglass and metal hulls. Aluminum hulls, on the other hand, will require stainless-steel housings.
