Whistler XTR-140 r/l detector


Whistler XTR- 140 r/l detector Features

The use of radar/laser speed trap detectors is endorsed by the traffic department.  According to superintendent Wayne Minnaar, Metro plikce spokesman for Gauteng (see The Citizen, August 2006) and Ian Auret, chairman of the Metro committee on road safety, the detectors 'slow the traffic down' 'enable the motorist to keep his eyes on the road' and 'promote traffic safety.

Whistler XTR-140 r/l detector is a voice activated detector with a range of over 1 kilometre for laser, and up to 7 ks. for radar.
