    • Excellent accuracy, ease of use, great price for the quality and features
Color: Red - Single Size: One Size
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. ... show more

    • Pretty good range finder
Color: Red - Single Size: One Size
I'm an avid golfer and a rangefinder is a must have. I have a garmin watch that usually gives me some distances but I use the range finger when I need an exact distance with slope. The Callaway Golf 300 Pro Rangefinder provides accurate distances with some cool features. It'll vibrate to let you know that the laser is locked so you can get your distance. You can also get a slope measurement or even turn it off. It's on the pricier side and doesn't seem worth it unless you can really hit your distances. The magnet that's built in is pretty strong and won't fall off. Actually it's a problem because I keep leaving the dang thing in carts; I'd recommend writing your number on the thing or add a sticker. I've left it at least 5x and the pro shop calls me every time. Highlights - Pulse technology - vibrates when locked so you can trust the distance - Strong magnet so you can keep it on your cart - Seemingly accurate distances (unless I actually measured it, which I'm not going to, I trust it); seems to coincide well with my Garmin that uses GPS. Overall, it's a really solid range finder. I don't recommend it for beginners who are just starting because it's got features that you probably won't make use of but as you get better and take into account slope; it's worth the price tag. ... show more

    • Great Callaway Rangefinder
Color: Red - Single Size: One Size
Great rangefinder for the money. Appears to be very accurate and built to high quality standards. I really like the feature where the unit vibrates as it locks on to the flag stick. Highly recommended.

    • Works well but yardage can vary by just a little
Color: Red - Single Size: One Size
I really like this rangefinder because it is easy to lock onto the target quickly and the yardage remains on the screen long enough to read it. The slope feature works well. The only thing I have noticed is that if I shoot the yardage to the pin several times from the same exact location, I will often get yardages that vary by 1-2 yards. IMO, Not enough to make a difference, but enough to deduct one star from my review. The magnet is strong enough to hold it to the golf cart window frame, but I don't do that because the instructions warn that the device can be damaged by direct sunlight entering the optics. This rangefinder is small enough to keep in my pants pocket comfortably on those cart path only days, but it can also be kept in the holder if you attach it to your golf bag. You can leave the holder unzipped and just close it with the stretch cord so access is easier than constant unzipping. I haven't had to change the battery yet, but I expect it will last at least 6 months using it for two rounds a week. ... show more

    • Easy for an amateur like me to use
Color: Red - Single Size: One Size
Simple to use, compact, nice carrying case and accurate. I was amazed at how it could lock on to the flag after giving me a couple of seconds to point, even with my shaky hands! WAY better than I had even hoped for!!!

This is a great rangefinder. It's smaller than what you might be used to but it works great and costs half of larger ones.

I am so happy with this rangefinder. It is so easy to use and the eye piece is crystal clear. I had purchase a cheaper style / model prior and it was practically unusable -- so I was pleasantly surprised that this Callaway is so user friendly

    • Nice product but pricing is out of control.
Color: Red - Single Size: One Size
I like it, and it’s unfortunate to see the scammy pricing now. I bought this 17 months ago for $132, yet now it’s over $200 and claiming to be 30% off. That’s too bad. For what it’s worth, I’ve used it at shooting ranges and it does what I need it to do. Wouldn’t buy another on the principal of this outrageous price increase. ... show more
