Yeh, I am the one that started the other thread on 15 years of V1 ownership and going to sell all my stuff on eBay, thinking the Bel 995 was just as good.
Well......... as I was boxing everything up, I took a few hours to do some final testing. It turned out to be very informative.
A LEO was using Ka in both instant and constant-on mode. He sat there for about an hour. Nice. Further down the same road is a "this is your speed" sign on K band. What a setup! It's a busy road so I did not stand out too much by making multiple passes. I made 18 passes (9 round trips). No I am not kidding. I wanted to be sure what I was seeing was repeatable (it was).
I had a V1 3.826 (POP on, Advanced Logic mode, large L) and Bel 995 4.5 (POP off, Highway mode) mounted high on the windshield, but below the tint strip. On various passes I used both units at the same time and one at a time, to rule out interference between units from their LO's. I also swapped positions. I covered all the bases to compare the units.
K band - sometimes one unit would alert slightly more than the other, but it was random. I am convinced they are just about equal.
Ka band - Sheeze! You got to be kidding. I thought the reviews said the Bel was just as sensitive. Kids, that's not the case here. In every single pass, the V1 alerted a LOT sooner than the Bel 995. The PSL was 40MPH, and at that speed the V1 would start alerting a at least 15 seconds sooner. This is critical time to slow down. This is critical sensitivity needed to detect Ka in instant-on mode being used on other targets ahead of you.
40MPH is equal to .01111 miles/sec. So, 15 seconds at this speed is 0.17 miles. That may not sound very far, but look at a clock for 15 seconds and it's a huge difference.
Has anyone else done a side-by-side comparison like this? Let me know your result.
PS, the V1 did J-out once on the LEO. Other cars were around. One of the probably had a Cobra RD. However, it had already given me plenty of notice. Not a big deal to me, it's VR way of dealing with POP. On the Bel 995, if I enable POP I get random alerts, that's a lot worse, so I keep POP off on that unit.
