–are devices for safety and navigation, and had different displays than fishfinders. A basic fathometer may only show a digital indication of depth, not a “picture”
– must use a graphical display to show fish in relation to the surface and bottom. They may also show characteristics of the bottom, such as hardness.
•With modern computerized chartplotters for data fusion, the plotter can show both depth and fishfinding displays, perhaps combined with radar and certainly
position information from GPS. Temperature information also can
be fused into a two- or three-dimensional diagram.
•Some fish finders/fathometers, even though they run on a dedicated computer, still can connect to your GPS and possibly other sensors.
In the example on the right, you'll see the display from P-Sea's depth sounder, which can run on any modern Windows computer. It uses 1000
watt/dual-frequency black box depth sounder with bottom classification
ability and A-Scope. It also can read temperature down to
the 100th of a degree
echo sounders, as well as chartplotters to which echo locators can
talk, can display 2D or 3D, at different resolutions. Here's a WindPlot
–Most interconnections will be NMEA 0183
–Have you interconnected to maximum advantage? Beachwerks can do the connecting.
