Callaway 300 Pro Laser Rangefinder with Slope Measurement

So far (after about 3 weeks), I am extremely pleased with the 300 Pro. Works very well for me and is a good price compared to others offering the same number of features. I looked at the Bushnell Hybrid Rangefinder before buying the Callaway. Although it has some features that might be kind of cool, at $400 you would think it could give you slope (I suppose irrelevant it you only play on a very flat course), and you would think it would have a magnet (or other cart attachment device) at this price (they do offer an accessory for cart attachment for additional money). I'm not slamming Bushnell as they make very good products, and I am guessing the Hybrid is very good, but at more than twice the price and without offering what I consider to be a couple of key features, for me the decision is a no-brainer. As to a couple of reviews I saw making complaints about the 300 Pro: (1) Small size: Some reviews complain that it is too small. I like it (although it has a magnet to attach to golf cart, it also fits nicely in the golf cart cup holder). My golfing buddy has a much larger rangefinder (I do not know the brand) which is no easier to aim than mine. He is very impressed with the smaller size and how quickly it gives a readout compared to his rangefinder. (2) Battery life: one review says the battery drains too quickly. At least from my experience, after 8 rounds over three weeks, I am still using the same battery without any issue. As I always do for battery powered products, I bought additional batteries at the same time on Amazon: "EBL CR2 Lithium Battery, 3 Volt 800mAh Photo Battery for Mini 25, Mini 50, Golf Rangefinder, Flashlight, Electronic Toys, Alarm Systems (CR2-8 Count)," about $12 for 8 of them. Even if I had to use a new battery every round, when paying $50-$100 per round I would not mind paying $1.50 to get accurate yardages for the round! (After 8 rounds I am only paying about $0.25 per round, assuming mine dies before round 9!) Sept 6, 2021: Update re battery. Four additional weeks and 6 additional rounds. Still on first battery. November 1, 2022: My last update for this product. Today my first battery finally ran out on the first hole. AFTER 101 ROUNDS SINCE 9/6/21!!! Obviously I did not need to buy all the extra batteries.

Good product. Unfortunately, want to get a second piece but price went up!

I was used to using the cheaper china units. I spent more on this Callaway rangefinder and it was worth every penny. No more frustration getting the useless yardage of the trees in the background instead of the pin yardage. This unit locks on to the pin quickly and provides accurate yardage.

Convenient and user friendly.

Easy to use, great pin recognition.
