I normally use V1 (All bogeys mode) in NY and STi (Highway mode) further north, but happened to have both going in NY the other day. STi was in tec display mode, and displayed freq numbers of 34.6 (3x), 34.7 (5x) and 34.9 (2x) for all hits (about 10 in total, all Ka and presumably Stalker Dual). For all instant-on and most constant-on, both V1 and STi were giving similar warnings. But, for one opposite-direction LEO in an SUV running constant-on, the STi gave me half a mile of continuous warning but the V1 never made a peep. Any ideas why?
