The Lowrance Hook Reveal 5X SplitShot also utilizes a FishReveal function to differentiate between fish and other miscellaneous instances of sonar return.

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.

This sonar operates at 200 kHz, and probes to a maximum depth of 1,600 feet in freshwater, and 750 feet in saltwater.

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.
