Under the See

|| |---| || |The touch screen of the i3 can be packed with chart plotter information or (below) show both fishfinder and 3-D contour charts on a split screen.| The Maptech i3 integrates navigation, radar, fishfinder and communications functions with touch-screen capability and contour 3-D charts. In a fishing test of the unit on Chesapeake Bay with two of the developers of the i3 charts, we cruised with the chart plotter with radar overlay and 3-D contour charts in a split screen. When we slowed to troll, we switched to a split screen with the fishfinder and contour charts. The fishfinder - a new module - uses a 170 kHz transducer (either transom-mount or through-hull) with a 22-degree beam to depict fish targets and bottom composition and structure. The fishfinder can place the fish targets on the 3-D contour chart, an interesting effect that gives a sense of the fish around the boat, even labeling them with their respective depths. The touch screen allows for easy data manipulation, such as rotating the 3-D contour chart for different views of underwater structure, or scrolling back through recorded fishfinder data linked to a GPS record. The chart plotter and radar use the same intuitive touch screen to adjust their settings. The i3 starts at $12,500. Maptech; (888) 839-5551; www.maptech.com. - Jason Y. Wood

Sound Check

The ART-3 antenna and radio tester from Shakespeare lets users test their own radios, without requiring unreliable radio-check calls. Operating on either battery power or 12-volt DC, the meter tests both receiver function and transmitter output power as well as antenna efficiency. The compact device is simple to use and sells for $90. Shakespeare; (803) 227-1590; www.shakespeare-marine.com.
