This Bel is a more "fine tuned" version over the 8500 X50 I had. Better alert tones, better menu, better threat display etc. Very happy with the product upgrade!
Only minor concerns I have is the 8500 went to a solid tone at full alert. The Bel seems like it is still "ramping up" audio when the visual is at full alert. Seems odd when I was looking at a full alert on the display with a half hearted tone rate. Almost did not take the threat seriously.
Also, how does this compare range wise to the 8500 X50? KA is very important. I have an M4 platform...
