I'm a gadget geek, so I own at least one example of almost every platform offered by Belscort. (S7,M4,M3) I also run a V1 3.864. And LIDAR jammers on all 4 vehicles I drive. (although my work vehicle is so big that the LED jammer on that thing probably provides almost no protection)

M3's are the most sensitive units on the market. (Escort Redline, 9500CI, Bel STi, Sti-R, STi-R+) I almost forgot; the M3's are stealth and undetectable to radar detector detectors.

V1 is the next most sensitive unit on the market and uses arrows to help you locate the source of radar. (Helps you know when you are "done" with a given alert sooner) V1 is also the most "responsive" RD on the market. Although a "segmented" M3 is right there with the V1. (STi-R and STi-R+)

S7's (older belscort platform that's no longer sold) are next with good all around performance.

M4's (Almost every thing else offered by Belscort at the moment) have good sensitivity for radar that's in front of you, even over a hill, but falls off once the source is off at an angle. (around a curve) M4's are as good as a V1 on one particular Ka frequency. (35.5 Ghz) Still slower to respond on all bands though. (takes a bit to "process" and then alert.)

Belscort's use of GPS on some M4 and M3 units has almost perfected false-alarm rejection and also can alert to cameras.
