Comparison Lowrance Hook Reveal 7 SplitShot vs Lowrance Hook Reveal 7 TripleShot

Availability of the side scan function in the echo sounder.

Devices with this feature are able to "see" the bottom and underwater objects not only directly under the vessel, but also on the sides of it. Note that different models can differ markedly in the angle of coverage of the side space. However, the side scan anyway expands the capabilities of the echo sounder and provides additional features compared to the usual bottom one.

The presence of a digital data processing system (DSP) in the design of the echo sounder.

Digital processing allows you to separate the received signal into extraneous noise and useful data. Of course, such a division is not 100% reliable; however, the level of noise in the filtered signal is still significantly reduced, and the screen receives a maximum of useful information and a minimum of extraneous information. The disadvantage of this function is traditional: echo sounders with DSP are somewhat more expensive than usual ones.

Possibility of operation of the device with the navigation satellite system GLONASS.

GLONASS (GLOBAL NAVIGATION Sputnik System) is a Russian satellite navigation system positioned as an alternative to GPS. Today it is the second (besides the same GPS) worldwide satellite network. At the same time, in modern electronics, both systems do not compete as much as complement each other: GLONASS support in echo sounders / chartplotters is usually combined with a GPS module (see above). Thanks to this, the device can determine its coordinates from signals from two networks at once, which significantly improves positioning accuracy. In addition, this combination provides an additional guarantee in the event of a failure in the operation of one of the networks.
