On my first two outings with my Athlon, I had really far offset numbers, very sporadic results both high and low on the first outing compared to my LabRadar LX and my Garmin, with these two units agreeing within a 2-3fps offset, but the Athlon ranging from -13 below to +25-30 above these two. On the second day with the Athlon, I had another Garmin and another Athlon set up all side by side - 5 chronos running concurrently. The 2x Garmins were within 1.5fps (usually within 3/4), the LabRadar slightly faster again by a couple of fps, then BOTH Athlons were running higher than the other 3 by ~20fps rather consistently. Athlon responded that a factory reset should fix that offset. For what it is worth, I did not do the offset before this subsequent outing, hoping I would see the same offset and a correction after doing the reset, but the offset was gone during this trip.
I shot ~200 rounds across the units installed into that test fixture two days ago, and unfortunately had significant co-channel interference which caused me to remove my LabRadar V1 and a Caldwell Velociradar from the comparison, but I stored a continuous string of over 100 rounds for all 6 units (2x Athlons, 2x LabRadar LX’s, and 2x Garmins) - I’m compiling data now, but will admit, exporting the strings from all 6 units has been frustrating - I cannot get one of my Athlons to sync to my phone at all, it will connect and will confirm connection on both ends, even to the point of allowing the firmware update, but it will not sync the sessions, despite a few hours of reinstalling my app, reconnecting the devices, powering off and on, etc. I cannot get this particular Athlon to sync.
I DO have some fits that occasionally my Garmin will sync to the wrong phone, then it won’t send the sessions to the correct phone, but this isn’t so much of a problem, I simply export from whichever phone receives the data, BUT this Athlon won’t send the info anywhere.
