Comparison Lowrance Hook2 5x SplitShot vs Lowrance Hook2 5 SplitShot

The presence of a native GPS satellite navigation module in a device with a chartplotter function (see “Type”). This module is responsible for determining the current geographic coordinates of the device and is thus a key element required for effective work with maps. At the same time, there are chartplotters that do not have this function — they are designed to connect an external GPS receiver.

The presence of a base card in the delivery set of the device.

The base map is a pre-installed map that is stored in the device's memory. Thus, a chartplotter in this configuration can (theoretically) be used out of the box without installing additional software. In fact, although basemaps may vary by model, manufacturer, and region, they are often small scale, displaying only the most general (often outdated) information, and unsuitable for professional use. Therefore, this function, usually, does not eliminate the need to install additional detailed maps (see below).

Ability to load new navigation charts into the chartplotter.

This possibility is extremely important in the light of two points. First, the base map (see above) rarely provides the level of detail needed to be used effectively — you have to download more detailed maps of individual areas. Secondly, it is very desirable to update even already loaded maps from time to time, since hydrographic information (depths, currents, shoals, fairway location, etc.) is constantly changing.

The maximum number of individual waypoints that can be stored in the chartplotter's memory.

Waypoints can be used as a base for routing, as reference marks on a map, such a point can be set as an immediate destination, etc.; specific use cases depend on the instrument model. But anyway, the more waypoints you can simultaneously enter into the chartplotter's memory, the more convenient it is to work with them and the less often you have to clean this memory to make new marks.

The maximum number of tracks that can be stored in the chartplotter's memory at one time.

If you have to regularly travel on fixed routes, it is much more convenient to memorize these routes once and then select the desired option than to reprogram the navigator each time. Modern devices can store several tens or even hundreds of routes; the larger this number, the less often you have to free up memory for new routes.
