DF ExtremeTag

Designed for motorsport.

The Trident DF ExtremeTag is an active tag designed for motorsport. The replaceable battery has a one-year lifespan and continuously powers the tag so that it is always transmitting, allowing you to get a read from cars, bikes or carts crossing the line at high speeds. The large antenna in the DF ExtremeTag is designed to maximise read rates at high speeds with the DF ActiveLoop.

DF ExtremeTag comes in two orientations, Vertical which means it must sit vertically to the ground. The tag is designed to fit on to the front fork or shocks of a motorbike, mountain bike, blokart or go-cart. Horizontal, which means it must sit horizontally to the ground. The tags can be mounted to the under-carriage of a bike or car.
