PS Tests Small-screen Plotter-sounders
Garmin 740s pushes the envelope for functionality and interface.
Practical Sailor tested four small-screen chartplotter-sounder combo units priced from $700 to $1,500: Raymarine A70D, Garmin 740S, Lowrance Elite-5, and the Humminbird 798si. While there was a disparity in what features the units offer, the plotter-sounders were similar in terms of the GPS-based functions. Testers looked at ease of installation, ease of use, screen visibility, resistance to fogging, and water/spray resistance. They also compared features including price, man-overboard functions, waypoint and route storage, available charts, chart interface, and user interface. This article focuses on the electronics' chartplotter capabilities. The December issue will include the report on the devices' sounder functions.
