Best GPS Fishfinder Combo in 2021

Lowrance HOOK Reveal 5x SplitShot

Best Overall: Sonar so efficient, that fish literally light up on your screen

Lowrance HOOK Reveal 5x SplitShot


  • Splitshot transducer for multi-level viewing
  • FishReveal function for easier identification of fish
  • GPS Plotter for simplified waypoint marking

The Lowrance Hook Reveal 5X SplitShot is likely to find favor among any anglers who are currently conflicted between whether to purchase CHIRP or down imaging sonar technology, as this unit possesses both capabilities. The Lowrance Hook Reveal 5X SplitShot uses a Splitshot transducer to cast both types of radar into the depths below, thereby providing anglers with a wealth of knowledge relating to fish location, bottom composition, and vegetation density.


Another unique feature of the Lowrance Hook Reveal 5X SplitShot is its auto tuning sonar function. When an angler boats into an area, the depth and conditions of the area being fished are calculated by the Reveal 5X, and provisions are made to provide optimal sonar operation. This feature should allow anglers to make more efficient use of their time on the water.

The Lowrance Hook Reveal 5X SplitShot also utilizes a FishReveal function to differentiate between fish and other miscellaneous instances of sonar return. When the Lowrance Hook Reveal 5X SplitShot recognizes the signature of a fish, it is illuminated to create contrast from other objects that are graphed. This provides anglers with a definitive representation of what lies beneath their boat.

Many anglers will also likely find value in the Lowrance Hook Reveal 5X SplitShot’s GPS Plotter function. This function allows anglers to instantly mark and store waypoints for future reference. This is a feature that should be immensely popular with tournament anglers, who often mark promising locations when prefishing, in an attempt to not waste time when returning on day one of the competition.    

Garmin 010-01550-00 Striker 4 with Transducer

Best Budget: Simple to use, yet comprehensive in features

Garmin 010-01550-00 Striker 4 with Transducer


  • Clear Vu technology for enhanced visual capabilities
  • GPS mapping for ease of navigation
  • Simple control interface for ease of use

The Garmin Striker 4 is likely to be a wonderful option for those who are new to fish finder use. This unit features a simple to operate interface, which should be easy to get the hang of for even the most inexperienced of users. In fact, with only an afternoon’s worth of use, most anglers become proficient enough in the use of this unit, that they can operate it with little to no issue.


Another noteworthy feature of the Garmin Striker 4 is its GPS enabled capabilities. If you stumble upon an excellent site during your next outing on the lake, simply mark it as a waypoint, and return to it time and time again. This is also quite handy when attempting to navigate new waters, where you have not previously ventured. Simply drop a waypoint at the boat ramp from which you launched, and travel toward this location should you become turned around.

The Garmin Striker 4 is also renowned for its depth of clarity, which comes as a byproduct of Garmin’s Clear Vu sonar technology. This sonar operates at 200 kHz, and probes to a maximum depth of 1,600 feet in freshwater, and 750 feet in saltwater. This should be plenty deep enough for most any fishing application, as clear images will be given to depths well in excess of where many game fish species are found.

This fish finder features a 3.5” color display, which provides an outstanding definition, and is easy to decipher. The unit’s resolution is high enough that anglers should be able to key in on subtle changes in bottom composition, and any form of submerged structure.

Together, these features should provide a highly efficient, yet user friendly interface that any angler could appreciate.


Much of the Garmin Striker Plus 5CV’s pronounced viewing capabilities stem from the unit’s use of not one, but two highly effective sonar platforms. This fish finder employs the use of both standard CHIRP sonar, and Garmin’s signature CHIRP Clear Vu sonar technology. Combined, these two applications produce high quality images of all that is taking place within close proximity to one’s boat.

The Garmin Striker Plus 5CV also features Garmin’s Quickdraw Contour Mapping software, which allows anglers to create and store up to 2 million acres of contour maps. This is a feature that should find favor among bass and crappie anglers, who often find themselves searching for suspended fish along drop offs, points, and channel ledges. You will no longer be forced to guess as to the whereabouts of this location, as your graph will present all information needed.

Another highly regarded feature of the Garmin Striker Plus 5CV is its bright 5 inch display, that can be read even in the face of direct sunlight. This is a feature that will likely save anglers time, and effort, as the need to stoop and bend to view a sonar display, will be a thing of the past. Images are also displayed in crystal clear clarity, thanks in large part to the unit’s 800 x 480 pixel count.

As a byproduct of this technology, the Striker Plus 4 provides excellent target separation, and is capable of detecting contour fluctuations of as little as 1’.

The Garmin Striker Plus 4 features a wealth of GPS enabled capabilities, which makes it possible for anglers to drop waypoints whenever they have located a point of interest. This unit also comes preloaded with Garmin’s quickdraw contour mapping software, which makes it possible to reference up to 2 million acres of referenceable contour maps on a single unit.

Most anglers are also likely to appreciate the Striker 4 Plus’ easy to use interface, which allows simple navigation through various menu screens and maps. This unit is also renowned for its sizable 4.3 inch display screen, with a 272 X 480 pixel count.

One can also load additional maps onto the Helix 5, through the use of the unit’s SD port, which further expands its guidance and mapping capabilities. One can simply store a map of any type onto a SD card, and place it within their Helix 5 unit, and this map too, will be at their fingertips anytime that they are on the water. 

The Humminbird Helix 5 CHirp is also notable for its use of both side imaging and down imaging. Each of these two capabilities provide a different vantage point of what is going on beneath water’s surface. Down imaging is especially known for its crystal clear depiction of structure, and high-resolution capabilities. The unit’s CHIRP sonar is also largely impervious to any forign form interference, which bolsters the Helix 5’s reliability.

This feature should be especially well received by avid crappie anglers, who often rely upon contour maps to locate suspended post-spawn fish.

The Garmin Striker 4CV also features first-in-class GPS capabilities, which allows anglers to mark a nearly infinite number of waypoints. In doing so, anglers are able to access prior points of interest in a far more efficient manner than they would have previously thought possible. This feature alone should make it possible to spend more time fishing, instead of boating around in search of your honey hole.

Many anglers should also find favor in the Garmin Striker 4CV’s 300 watts (RMS) power rating. This robust output allows the Striker 4CV’s transducer signal to push through minor obstructions, such as silt, and penetrate deeper than many other units in its class. As a result, anglers using this unit should notice little in the way of feedback.

Final Thoughts

When purchasing a fishfinder of any type, one must first consider their budget. Fishfinders can be somewhat pricey, depending upon the exact unit that is selected. However, as is illustrated by a number of the above mentioned products, one can purchase a more than capable fish finder unit at a reasonable price. Once an appropriate budget has been decided upon, it is best to seek out the best unit that is available at that given price point. This provides you with the most bang for your buck, and ensures that you will be satisfied with your purchase for years to come.

It is also important to consider any personal preferences that you might have when selecting a fishfinder. While some anglers are fond of one particular brand of fishfinder, others are not. The same applies in regards to features. If you have located a certain format of fishfinder in the past that you have found favor in, sticking with products of a similar make can often prove helpful.

When in doubt, always stick with products from the industry’s big-three brands, Lowrance, Humminbird, and Garmin. By doing so, you can rest assured that you should be purchasing a quality product that will have plenty to offer. At the very least, you will also be provided with peace of mind knowing that you will be doing business with industry professionals who will honor their warranties should a problem arise, rather than a new fly-by-night company.
