You won't have to request a radio check when you've got this convenient, user-friendly device onboard. Unlike similar meters, the ART-3 goes beyond the basics, evaluating receiver performance, output power, and antenna efficiency (VSWR). It can run on its built-in battery or be connected to the ship's 12 VDC system using the included power cable. You can easily check the battery level with a simple flip of a switch. Every dedicated boater should have an ART-3 at their disposal.
