I purchased this unit for my sister and was testing it with my bushnel k-band gun. Althoght not a real police radar gun. It has alsways reported k-band on my x50 and v1. To my surprise every couple of times it would report x-band. Im kinda weary now bc i know my sister will ignore all x-band alerts seeing how their all doors or banks in my area. Will this happen with a real police k-band radar unit? Anyone else have similarites with the pro 58 or 73?
