"Is any radar/receiver system used primarily for the long-range detection of its targets, i.e., allowing defences to be alerted as early as possible before the intruder reaches its target, giving the defences the maximum time in which to operate." Thanks wiki
The V1 has the arrows and superior Instant on and Q/T detection over long/short distance.
The red line/9500ci/sti R have superior C/O, around the bend detection over a greater distance (not by much).
So IMO the V1 is the better detector hands down. Not to mention the build quality,history,cost.
What say you bell boys?
