Speed Tools Give Racing Sailors Starting-line Advantage
Velociteks new ProStart fends off challenge from remote-control RockBox.
Speed-gauging tools developed for racing sailors have moved beyond a simple display of measuring knots, and now offer heading data, course over ground, distance-to-line, and GPS speed-tracking features. Velocitek is leading the marine electronics field of handheld speed tools with its ProStart, while Rock City Marine's RockBox, like the ProStart, uses GPS satellite signals to monitor speed and performance. Testers looked at each models ease of installation, performance on the water, and durability. Testers also rated their accompanying software.
