Sonar Technologies Anglers Must Know About

There are three basic sonar technologies found in portable fish spotters, more precisely the fixed frequency sonar technology, the StructureScan sonar technology, and the CHIRP sonar technology. Each of them has different traits and elements that make it a more or less desirable option for anglers, and we recommend you first learn more about each tech before jumping to make a rushed purchase.

  • Fixed Frequency Sonar

As the wave emitted by the sonar strikes an object, it rebounds, this being the action through which the transducer is able to provide you with a mapping of what lays underwater. With fixed frequency sonars, the common frequencies used are 50 kHz and 200 kHz.

Characteristics of 50 kHz frequencies:

  • Wide cone angle;
  • Higher noise susceptibility;
  • Less target dissociation;
  • Deep depths.

Characteristics of 200 kHz frequencies:

  • Narrow cone angle;
  • Lower noise susceptibility;
  • Superior target dissociation;
  • Shallow depths.

Fixed frequency sonar advantages:

  • Old-style tech that has been proven to work;
  • Cross compatible with multiple sonar generations;
  • Lower cost.
  • StructureScan Sonar

StuncureScan implementations incorporate sonar image down-scanning and picture-like views of the water underneath and around the boat. Their precise display of depth and distance-related information take all of the guesswork out of using the sonar. Also, they provide imagines that do not actually require any interpretation.

StructureScan sonar advantages:

  • Slice yields detail-rich images of structures within close ranges;
  • Endorses quick selection and identification of the target area.
  • CHIRP Sonar

CHIRP stands for Compressed High Intensity Radar Pulse, and it is characterized through its transmission of long pulses across wide frequency bands. Although CHIRP used to be an expensive technology to use in devices, it is now more accessible, being widely used for recreational purposes as a result of this accessibility.

CHIRP sonar advantages:

  • More accurate detailing and greater resolution;
  • Accuracy at big depths of 10000 feet;
  • Better bottom tracking at high speeds;
  • Better signal to noise ratio;
  • Large transmission pulse lengths;
  • Low power consumption;
  • Better shallow water performance.

Frequently Asked Questions

?Why does its waterproof rating matter?
Even though you consider yourself as being careful, you never know when a wave sends off water into your fishing boat. As this happens and the water lands on the fish finding device, it will ultimately be damaged if it is not water resistant or waterproof. Obviously, it is preferable for it to have a high waterproof rating in order to ensure that it will suffer no damage in the off-chance that water lands on it or you accidentally drop it in the aquatic environment.

?Can it be used by kayak fishermen?
Yes, all portable fish trackers are suited for use on kayaks precisely due to their portable element. Kayak fishermen actually prefer these models as they can easily mount the fish tracking devices at the beginning of the fishing session, and take them out when it is done. Also, the compact size of portable finders makes them ideal in this environment as they occupy little space in this otherwise finite space place.

?Can it be used for ice fishing?
While all portable fish spotters can be used for shallow and deep water fishing, regardless of their design and specs, when it comes to ice fishing matters are not as simple. Due to the harsh environmental conditions that play out during an ice fishing session, you need to invest in a fish finder that can withstand the extreme cold temperatures.

Finding fish has never been made easier than with the use of the Deeper PRO+, a device that was an obvious choice for our number one spot as it features WiFi powered connectivity, being compatible with Android and iOS smart devices. This makes it highly convenient and intuitive to use, modernizing the art of angling and providing you with the chance of accurately and easily finding groups of fish in the body of water you are in. Another element that convinced us to rank it so high is its plethora of features, its 330-foot wireless operating range, and the 260-foot maximum depth.

A model that really caught our eye, so we ultimately ranked it high as a result of its overall performance is the Garmin Striker 4. It is rated IPX7, so direct contact with water won’t affect it at all, and it comes with a multitude of features, the one that impressed us the most definitely being the AutoGain technology that minimizes the clutter on-screen and maximizes the targets, making it easier for you to pinpoint where the fish are. Another entry we view as mention-worthy in the conclusion of this article is the Venterior VT-FF001 that features a 5-level adjustable sensitivity and boasts a maximum depth rating of 328 feet, all while managing to remain budget-friendly.
