Why does my Varia App only show vehicle detection up to about 80 meters instead of 140 m?

Hi everyone,

The product documentation states that the radar can detect vehicles up to 140 m (approx. 153 yd) away.
However, I found that when a car icon first appears at the very bottom of the Varia App screen, the actual measured distance to the vehicle is only about 80 m.

I physically stopped the car at that point and measured the distance with a laser rangefinder — it was consistently around 80 m.

It seems like both the visual display range in the App and the actual alert distance top out around 80 m.

Is this a known limitation of the Varia App’s display scale, or does the radar itself limit detection distance depending on angle, environment, or target type?

I’d appreciate any insights or similar experiences from other users.

Thanks in advance!
