This is the rangefinder that I am currently using and I really don't have many bad things to say about it. Truthfully, there is not much to say about a rangefinder product in general, because it is meant to serve a single purpose:
Measure the correct distance
If it does that, is moderately waterproof, and doesn't lose battery every 5 rounds, it's a good product in my opinion. This product does all of those things which is why it is at the top of my list. You could upgrade to the "Shift" version, but the additional feature of slope measurement is not worth it in my opinion. Unless you are playing competitively and need it for practice rounds only, I would just use Google Earth to measure slopes for the courses you play.
Overall, if you're looking for a rangefinder to start with that will last you for the rest of your time as a golfer, this is your product. You really can't go wrong with this product or brand.
