Still, it is important to note that the detail level is truly low. However, the unit WILL be able to indicate your current location and serve as a plotter. They will not provide you with any contour data or other useful information like lighthouses or marine services. The model we are talking about in this review comes with preloaded BaseMap charts, which are pretty rudimentary, as the name suggests. It refreshes every single second and it can also measure the speed of your vessel. Lowrance Hook 7 comes with a built-in 16-channel GPS antenna, which ensures fast and accurate positioning and locks. It will provide you with photo-like quality images and give you a proper understanding of all the structures and potential targets under your vessel.įinally, Lowrance Hook 7 also comes with numerous sonar functions, including Advanced Singal Processing (also works with DownScan), Sonar Recording and TrackBack, DownScan Overlay to combine your 2D and DownScan views, Bottom Lock, A-Scope, Split-Flasher, and Fish ID with several depth and fish alarms. While the 2D CHIRP sonar is excellent at locating and separating individual fish targets, DownScan is much better at determining the shapes of underwater structures and the overall bottom constitution. The provided transducer comes with a temperature sensor, transom mount, and 20ft of power cable.

In other words, you will have med and high CHIRP at your disposal, but you can also upgrade the unit with a 50/200 kHz transducer and use low CHIRP. Note that the unit is not capable of SideScan imaging.įor the CHIRP sonar, the transducer utilizes two conical beams at 20° for 200 kHz and 60° for 83 kHz. The provided transducer is capable of 83/200/455/800 kHz, which means you can utilize two sonar beams for CHIRP scanning and two for DownScan. Lowrance Hook 7 comes with a regular CHIRP sonar as well as DownScan.
