Today while on the highway on my way to work I got blaster with laser (Pro Laser III) at less then 500' just as I am turning the corner. The Pro 78 alerted me which is impressive since the beam is so little at less than 500'. My LPP's jammed the hell out of him and the Pro 78 alerted the entire time. I have had two laser encounters with the Pro 78 and it has alerted me EVERY TIME. I would rank its laser detection as good as the X50. Is there anything this Pro 78 can not do? It does everything well. IMO it is the Scottie Pippen of radar detectors. It does not do anything excellent but everything good. VERY SOLID!
