“There are many of these out there and they all do a good job. Ultimately it comes down to which you like the appearance of the best. I will say get one with a magnet. But the NX9 is great, no complaints but nothing earth shattering that make it better than the Blue Tees for example. The NX9 also fits in your back pocket well for those cart path only days and you have to hit a shot before going back to the cart.
Note: I’ve had the TecTecTec and it eventually failed/broke.”
“I have always used a Garmin watch to judge distances until I bought the NX9 Slope Rangefinder. I felt I wasn't ever good enough to use a Rangefinder, but now I know that was the wrong thinking. It has made a huge difference in all my approaches to the greens. I am picking better clubs to use because of it and tend stay on the green instead of going to far or coming up short. It is so easy to use and amazingly accurate. I love it !!”
