You have tried everything…you have searched everywhere, but still, it feels like you are banging your head against a wall.

If it is still a hurdle choosing the best depth finder in a market that’s flooded with several brands then you are in the right place.

The ideal top rated fish finder should not only be fancy but an excellent deal for;

  • Easy navigation on the water.
  • A remarkable depth of reach.
  • Reliable power output.
  • A large and clear display, and
  • It is easy to operate.

I have compiled a comprehensive analysis of three brands of the best fish locators in the market.

General Overview and History – Best Fish Finder

But before getting into the tiny details. How about a flashback to where it all started? Here’s a sneak peek of the history of the top three fish locator brands in the market.

1. Lowrance Fish Finders

Lowrance was established in 1957 and is a leading producer of marine electronic equipment. In particular, Lowrance manufactures sonar receivers, GPS receiver, and digital mapping systems.

But what makes it unique from other brands is its high definition systems (HDS). Also, it has remarkable high-performance add-ons such as Broadband 4G radar, structure scan, side scan, and down scan imaging.

But that’s not all.

Some others include; Sonic Hub Aucho, Sirius LWX-1 weather, and NAIS Collision Avoidance.

Lowrance is owned by Navico Corporation after it merged with Simrad Yachting back in 2006. Currently, the company has a good employee base that supplies marine equipment to over 100 countries globally.

2. Humminbird Fish Finders

This company and fish finder brand was established in 1971 by Tom Mann and a couple of like-minded investors. Like many other companies, they had a humble beginning where they started in a garage store.

In its early years of establishment, this brand was associated with giving priority to what fishing enthusiasts really cared about. This is seen in the way the company inquired with her customers on what they wanted.

The response was less complicated units that are easy to operate and have a user-friendly display. This marked the beginning of a lifetime of transformation. Today, these features flow from one product to another.

Also, Humminbird has been responsive to technology. First, it was the first to introduce waterproof fish finder equipment.

Second, it’s among the first brands to use an LCR screen display. And third, it’s the pioneer in the use of 360 degrees sonar technology.

3. Garmin Fish Finders

Garmin Company, previously known as ProNav, was founded in 1989 by Gary Burrel and Min Kao and is headquartered in Kansas, USA. Its first-ever customer was the US army where it sold GPS units.

Therefore, the key defining feature of Garmin is the GPS technology which is consistently fused in its products. Besides the marine space, it has other products related to wearables such as wristwatches and aviation.

Others include; use in automotive, sports and fitness, and in outdoor recreation. The GPS technology makes it possible to experience the ease of navigation when you have a Garmin product.

In the marine space–our primary concern–it has a variety of GPS enabled devices that make fishing an exciting adventure.

Some of these include; GPSMAP plus, ECHOMAP UHD, PANOPTIX Livescope, and ice fishing bundle. Others are; US/Canada LakeVu G3, Bluechart Trolling G3, amongst many others.

With Garmin, you will have a range of fish locator equipment at your disposal. More importantly, its GPS technology will help with easy navigation and improved productivity.
