a very long time.im getting rid of my v1's.my 3.826,my 1.7 and if i can find my other one in my room. there looking for new owner's.

For those interested, I have performed an extensive examination of both detectors on a multi-state 2000+ mile trip. I'll have a write up coming along with a bunch of video documentation as well.

Be aware that the manufacturing variance is not negligible. We did a comparison test with 3 different STI-R (different age), in the same mounting position (clear view of the road) against a stationary radar source (34,3 GHz, empty road) and we were surprised about the difference in sensitivity.

What did you observe? Over what periods of age were the three units?

how long have you had the V1 for rob?

LMAO! That was from the humancentiPad episode!

I too have seen major manufacturing among Belscort units, in fact more so than any other manufacturer. The models I have tested and found significant differences have been: 3 RX65's, 2 8500's, 3 8500 X50's, 2 STI R's, 2 9500CI's, 3 Redlines, 3 9500i's, 2 9500IX's.

Regarding the age: The oldest was about 3 years, the other two about 1,5 years old (one of the two had a LNA replacement including new calibration, software update,.. a few weeks before the test).

We set up a radar emitter at a lonely road without any traffic and made a few runs. I don't know the exact results any more, but from what I can remember the latest model had twice the range of the oldest one. The second STI-R was in between.

When we did some testing to find the optimum position against photo radar, we also discovered that two STI-R behaves completely different on the same position. For example we placed two new STI-R on the same position and discovered a difference in range of 50-70m (at a total range of 300m).
