A little better distance Whistler Radar Detector I have been playing around with my xtr and pro 78. I have found when you turn off sws, pop, x band, and even the compass off. For the xtr 690 and minus the compass on the pro 78 because the pro 78 doesnt have the compass. I notice a slight increase in range. You might say well you havent done any testing. No I haven't but I have driven long enough with these units to know when a slight increase has happen. Dont go expecting a 5 mile range increase. But it does offer a slight distance increase. |
