My V3 arrived Thursday. Thanks again budget golf for the 25% discount. Not being a person who wears a watch had me a little worried. No issues whatsoever. Have not installed sensors yet used V3 yesterday for front middle and back only. Worked great. On a couple occasions my V3 gave a different reading from tee box to green than my buddies garmin. Most times they were within a few yards but in the few occasions there was more than a 40 yd difference. Only reason I could come up with is V3 was giving straight line distance on a dogleg and other was giving a distance following contour of fairway. Any thoughts on this
