The STEALTH 4 laptimer

A very useful accessory for the race track, as you get direct feedback on your progress. Before the event, the laptimer can be loaded onto the relevant race track using a USB stick and the individual sectors can also be set. We have tested the device ourselves and are convinced of its ease of use; the buttons can be operated even when wearing gloves. Installation is also very simple, as the heat-resistant cable supplied is long enough to be pulled to the battery and the lap timer is then positioned on the tank or near the rev counter.

The revolutionary TWIN GPS concept and defines a new technological step in terms of GPS coverage reliability and timing precision. Thanks to the new internal TWIN GPS, consisting of the American "GPS" and the Russian "GLONASS", the Laptimer Stealth 4 has up to 16 satellites available for positioning. This means that not only your lap time is measured even more accurately. Even under difficult geographical conditions, such as the Nordschleife, there is always sufficient satellite coverage. Great attention was paid to protection against water and vibrations. The electronics in the front part of the housing are well decoupled from the rear housing by the new silicone seal. For mounting, a small retaining cap with an M8 screw for fastening with two additional rubber washers is included in the delivery. Alternatively, the 4 Velcro pads supplied can also be used.

The tilt angle is visible on both versions.
The Data version records the driving line compared to the Lite version.
