Incredible tool for increasing speed and staying on track in the winter. I’m a 5 handicap, 45 years old and went from 113 mph to 119 mph driver swing speed in just a few monthsI love the stack wedges to gamify my practice and can’t wait to try Stack putting. Dr. Sasho is the man.

The radar completes the Stack System. It has been worth the purchase. Highly recommended.

Get the entire Stack system. It has helped raise my swing 4 MPH in 10 days

Bought this to use with the stack speed training system. Works well integrated with the stack system and I also use it at the range to monitor my club and ball speed. It is a good low budget option versus a more expensive launch monitor. One thing to note, on driver pop-ups it tends to only read ball speed and shows inaccurate clubhead speed. Minor complaint, I wish it was rechargeable rather than needing to purchase batteries every couple months.

I can’t recommend this launch monitor at all. I sold my Rapsodo MLM2Pro hoping to get something easier and quicker to setup and use. This looked like the perfect solution, just put it behind the ball, select a club and go. Unfortunately it misses so many shots that it’s basically unusable. Someone from the company reached out to me and gave me some pointers on setting it up and where to place it behind the ball but it made no difference. It works roughly 70% of the time with driver, 50% of the time with wedges and even less with irons. Very disappointed because it is really simple to use and would be great if it actually worked as advertised.

This golf radar is a great way to see how fast you are hitting the ball. It’s a lot of fun for the entire family to do and watch. This item is small and compact so it’s easy to store in a bag or any where it is needed. This has great functionality. I took my son out to play golf and we really enjoyed this item at the golf range. good value for the money two thumbs up!
