What Golfers are Saying

I used it for the first time today it calculates the wind, the club selection. Everything absolutely perfectly the best rangefinder on the market.

- Timothy M.

Used my i4 this past week for the first time on the course and loved it! The effective playing distances and club recommendations were spot on. I do not have a FlightScope launch monitor so the smart gapping feature made it really easy.

- Tyler D.

I’m amazed how easy it is to use and how it correlates to the launch monitor. Great product.
