Athlon Rangecraft Compact Chrono Tested

[59FLH]

Yes, and no.

The photo with 8 units mounted above was taken during my pre-experimental DoE phase, during which I determined interference potential and identified units which don’t play nice together, and start up and channel assignment protocols to eliminate co-channel interference. The Caldwell didn’t play nice with one of the Athlons, so I cut it out - I had to reassign the LabRadar V1 channel, but aiming that thing is such a PITA, I cut it from that phase of the side by side test, and added a specific phase to test those individually against the Garmins as relative controls (only have one V1 and one Caldwell on hand).

So the data series’ captured in the rest of the matrix have been captured with the co-channel interference potential Eliminated.

There are multiple replicants of these tests in which the Athlons bounce above and below the other brands, but the Garmin and LabRadar tend to track together within the expected precision. No, this agreement is not a guarantee they are reading true velocity, but effectively, both Garmins and both LabRadars have to be WRONG if ONE of the Athlons is right (5 out of 6 must be wrong). Alternatively, all 4 of the LabRadar LX’s and Garmin’s could be right.

Better processing of the signal(s) in the Garmin & LR would be my guess. Not likely the antenna, but could be.
