Down-Scan Sonar Technology 

The Lowrance Hook 4 utilizes what’s known as down-scan sonar technology to produce incredibly clear and detailed images of the fish and any other type of underwater structure that might be lurking beneath one’s fishing vessel. This model uses CHIRP and down-scan sonar to create these images and help anglers gain a better understanding of what’s underneath the water’s surface. 

CHIRP (Compressed High-Intensity Radiated Pulse) was first used by law enforcement and various military units across the world to locate structures and a variety of other things that could otherwise only be visible to divers underwater. This technology transmits a series of low-frequency sonar pulses down below the boat which bounce off any structure and the bottom before returning to the device itself. Using these sonar pulses, the fish finder is able to compile a real-time image of everything below the water surface in any given area. 

When this technology was initially used by military forces and law enforcement officials, it quickly developed a reputation for being able to produce incredibly clear and revealing images of the many different types of fish that might be swimming around below a boat. Years later, companies like Lowrance have developed units that are more capable of providing images and information that anglers can use to increase their chances of success on the water. 

While this technology is very powerful, it is only able to scan downward directly below the vessel. The capability of knowing what’s below your boat is not only useful in catching fish, but also plays a role in making sure boaters and anglers stay safe while on the water as well. 

Important Data 

The most skilled anglers across the world are always paying attention to any pieces of data they can get their hands on. The Lowrance Hook 4 has the ability to record many different types of data points that will come in extremely useful for anglers of all skill levels. 

The device offers a TrackBack mode that allows users to view previously captured images of specific locations that they have visited in the past. This allows anglers to assess many different areas on a specific body of water and determine where fish might be located at certain times of the year based on underwater structure and formations. 

Anglers are able to ‘mark’ certain locations on their maps and reference them at any point in the future. These data points show the time, date, water temperature, and many other points of interest that anglers would want to pay attention to in making a decision and planning their approach to a certain body of water. 

GPS Location Capability 

Among the most important features of the Lowrance Hook 4 is the unit’s ability to display precise GPS locations at any given time. This goes a long way in helping anglers locate certain areas where they expect fish to be biting at a given time, but can also play a major role in safety as it is incredibly important for anglers to always be aware of their location and how to return to the boat ramp once they are done fishing. 

The Hook 4 comes with a built-in GPS that offers incredible memory capacity to mark locations, as well as help anglers explore thousands of lakes, rivers, and coastal areas. This fish finder offers detailed maps of more than 3,000 lakes in the United States and other countries. 

High Definition Imaging 

The Hook 4 also offers a crystal-clear picture that works at any time of the day or night, even when the sun is shining bright overhead. The screen is relatively small, but users should have no problem viewing the downscan imaging results and gaining a full understanding of what’s below them, as well as where the fish are located. The Lowrance Hook 4 offers 480 x 272 pixel imaging, which is much more clear than most brands and models of this size.
