No need to call for a radio check when you have this compact, easy to use, unit on-board. Unlike other meters in its class, the ART-3 tests receiver function as well as output power and VSWR (antenna efficiency). It is powered by an internal battery or can be connected to ship's 12 v.d.c. with the supplied power cable. Battery level can be checked at the flip of a switch. No serious boater should be without an ART-3.
