I found my old Bel 945i cordless this weekend while visiting my parents..... anyway, I decided to see how blind it is on Ka band, I tested it against my Kustom Talon 2 and guess what.... it did NOT miss a single QT. My redline will miss about 4 out of 5.
That was VERY unexpected. I assumed it would miss normal instant-on "Slow Trigger".
On the 900 mile drive home I used it for awhile (for fun) and it gave me a very decent warning on CO K-band and a CO X-Band (Ohio). Don't get me wrong, my redline crushes it but I was still a little surprised.
