I've had the XTR-695 for a little less than 2 weeks and have it installed alongside my V1. My daily commute consists of around 1 hour to work and an hour back.
I have only encountered K-band and Ka-band (34.7) during my commute.
K-band: In K-band, the V1 has no equal with respect to detection range and sensitivity in every conceivable circumstance. Around sweeping bends with little to no variances in elevation, the 695 does surprisingly well. But when there are some elevation changes thrown in the mix though, the detection range is hindered slightly.
Ka-band: In Ka-band (34.7), I have had limited encounters. With a mobile Ka equipped patrol unit coming towards me on the highway in the opposite lane sampling traffic IO, the alert from the XTR-695 came virtually at the same time as my V1. Detection range was not fantastic for either unit in that situation, but each unit gave enough warning to bleed off any speed.
False Alarm Suppression: I have my XTR-695 set in Highway Mode with the default (normal) Filtering option and both X-band and POP disabled. With these settings in mixed city/highway driving conditions, the XTR-695 is fairly quiet unit. Its false alarm supression is good - an order of magnitude better than the V1.
I have my own mini-review on the XTR-695 going in another
thread, so I'll be adding to it as my time with it continues.
