Veratron GO+ is a small interface that takes the engine data off a Suzuki outboard and puts it on a phone or tablet over Bluetooth. Revs, fuel flow, trim, hours, alarms and voltage, without cutting a hole in the console.
It is aimed at smaller boats where a fixed display is hard to justify, and at owners who want the data without a refit. For a rental fleet or a ski boat it is a cheap way to get engine visibility.
