To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Had the Coolshot for 3 rounds now and bought to use alongside my gps watch for more accurate pin distances. OK value for money but difficult so far to measure to the flag, or I find I compare with my gps and see it is often wrong or measuring to something else, especially if trees behind the green. Measures to landscape no bother. Yesterday in mist/light rain it was useless and couldn't detect anything other than the ground 30yds in front of me. So far not that impressed and still trust my watch. Maybe should have spent the extra for a Bushnell.
