GPS Rally Sending Unit with Zero Installation

Imagine using your existing TSD rally computer, any brand, in any vehicle, without having to install a sending unit, probe or sensor. The ALFA GPS-Pulser allows you to do exactly that. It plugs directly into the sending unit input of your rally computer or odometer, and provides exactly the same signal as a traditional wheel mounted device. Your computer may then use its standard odometer correction factor to match any course in the usual manner. All you do is toss it up on the dashboard, and drive! Also, because the ALFA GPS-Pulser uses a high precision GPS1 receiver, it always knows the exact time and can be used to sync the clocks in popular rally devices.
"Black Box”: Requires no setup. Just plug it in and drive.
