I have over 160 rounds in game golf. Just decided to try Arccos and I bought the 360 new. 4 out of 14 tags didn't work out of the box. I have two rounds so far but obviously it doesn't work very well when 4 clubs don't get their shots tracked.
Did those sensors not pair, or did pair and then failed to register shots?
What did their customer support say?
They didn't pair to start. Costumer support said 'manufacturing defect.' I will eventually get replacements but after I did overnight shipping to begin with it is sort of a let down. 4 out of 14 is a pretty bad failure rate.
Out of curiosity, do you know where the extra sensors shipped from?
