The 9 Best GPS Fishfinder Combo (2021 Reviews)

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.    

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.   

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 mentioned, the Garmin Striker Plus 4 features a dual beam transducer, for enhanced detection capabilities. This is a feature which is nearly unheard of at this price point, making the Striker Plus 4 quite the value for anglers of every skill type. 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. The sum of these features should allow this unit to be viewed in a clear, concise manner, even on the sunniest of days.  

Many anglers should find immense value in the Humminbird Helix 5 CHIRP’s AutoChart Live programming. This program allows you to create custom maps of any given body of water in a fully automated fashion. As you pilot your boat, information is automatically stored regarding lake bed contour, vegetation, and bottom hardness. This information can then be used from that point forward to seek out areas of promise, when attempting to locate fish in numbers.

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.

Another feature of the Garmin Striker 4CV, that is likely to become an instant hit with most anglers, is the mapping software, Garmin Quickdraw Contours. This software allows anglers to store and create maps that have 1’ contours for up to around 2 million acres. 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.

One of the Humminbird Helix 7 CHIRP’s most unique features is its Dual Spectrum programming. The use of this programming allows anglers to toggle between individual transducer modes to select their desired view of what lies beneath. When in Wide Mode, this unit scans the largest sweep of water possible, providing anglers with a significant scope of coverage. In Narrow Mode, a smaller area is scanned, with an ultra-high level of detail.

No matter its mode of operation, the Humminbird Helix 7 CHIRP should provide a level of image clarity that few other sonar units can match. This unit is created help you see each fish, reach greater depths and range, and clearly identify bait and structure. This level of ingenuity is likely to give tournament anglers the competitive edge that they seek.

The Humminbird Helix 7 CHIRP also features a pronounced 7 inch screen, on which all data can be viewed in vivid color. Additionally, users are given the option of toggling between numerous split screen menus, which allow for simultaneous viewing of maps, graphs, and images. This should be of immense benefit to those who are looking to maximize their efficiency while on the water.  

The Lowrance Hook2 5X is also easier than one might think to install. A single transducer can be mounted on the transom, inside the hull, on the trolling motor or through a scupper hole, allowing an angler to choose the particular mounting option that best suits their needs. With the unit’s transducer and operational interface in place, final connections can be made in a hassle-free manner. Overall, full installation can be achieved in as little as an hour.

Angler’s are also likely to find favor in the Lowrance Hook2 5X’s wide range of coverage. This unit offers a wide-range CHIRP sonar cone, which provides double the coverage of many traditional fish finders. This should make it easier than ever to cover water at a rapid pace, in search of fish in numbers.

The Hook 5x also features a host of GPS enabled capabilities. Anglers can easily mark waypoints with the press of a button, allowing simple navigation to and from such locations in the future. This interactive format is likely to find favor among anglers who fish multiple lakes on a regular basis, and must be able to cover water in the most efficient manner possible. 

The Humminbird Black Hook fishfinder also features Dual Beam Plus capabilities, which utilizes a wide beam angle for increased coverage. This allows anglers to stay abreast of numerous details that they might have otherwise missed when using a sonar unit that was more limited in the scope of its coverage. Consequently, this allows an angler to make better use of their time on the water.

This unit also features an astounding array of GPS based capabilities. The Humminbird Black Hook fishfinder employs the use of the company’s signature AutoChart Live programming, which scans and stores map and GPS data in real time. In turn, one is better able to cover water with confidence, knowing that their fishfinder is handling all of the mapping work for them.

The Humminbird Black hook also comes with everything that you need to complete the installation process. These supplies include a transducer and mounting hardware, power cable and gimbal mounting bracket. This eliminates the hassle of being forced to source additional mounting hardware, before the installation process can ever begin, which in turn gets you back on the water in record time.
