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.
Arrived promptly. Difficult to rate as I’d not had one before. I’ve only used it once and I found it difficult to hold steady and focus on the target. It give me more than one reading, probably of objects behind the flag. I have a GPS watch which also gives distance so I already have some idea of how far I need to hit it so this should give me a bit more accuracy. I will probably use it most on unfamiliar courses where I need a distance to bunkers or water etc.
