I have a 1.7. The version is 2.690. Should I upgrade or is this unit good enough? It has laser detection and no POP. It serves me well and the K and Ka range seems good. The laser is also good and it rarely falses. If I get a laser hit, it is a LEO. I am not sure about it's spectre performance but on the rare occasion I pass through Va. If V1 had a new model that was invisible to spectre I would upgrade. Any thoughts? Thanks.
