Be sure to read caution below about this V3 "Slope" model. You can't help but call this an excellent product. I've never used a golf laser finder. The ease and speed of use is amazing. It finds all targets easily and displays results instantly. The 5x brings distant targets into easy site range. I thought holding steadily for longer distances might be an issue, but it's really easy to get results. The new pin seeker technology, complete with jolt / vibrate when it locks on a target, is a nice touch. Note: It appears the pin seeker and jolt may activate only when a complex situation occurs. For example, the pin is in the foreground with bushes / trees behind, which might cause you to question "what" is being lasered. The pin seeker vibration confirms it knows there are bigger / other targets in the background, but has locked on to and is giving you the range to the closer target - good validation. This may be why some think the pin seeker / jolt doesn't work all the time. Reading the instructions may help. It seems if a pin is clearly identifiable, the distance is simply displayed. It is fool proof. Remarkable. It just works, instantly. Note, I am and will continue to be a skycaddie SGX user on the course, simply because of the complete information it provides like hole overview with bunkers, fairway ends, and ranges to 150 yards out - a more complete view of the hole. A laser will not replace my SkyCaddie.
I brought this V3 slope addition primarily for use on practice ranges that have mixed elevations (higher tee boxes, lower range targets, higher range targets, etc). Most times I just look at my SkyCaddieto see the pin distances based on where the teeing area is moved for the day and from where I set up to hit. The SkyCaddiefor most courses I have played include the driving ranges and target distances. For practice sessions, however, I really wanted to know the actual distance the practice target was "playing." At my primary, hilly driving facility, it turns out a "lower/downhill" target when lasered indicted 153 yards (which agreed with the SkyCaddie), but plays as 145 yards and "n" degrees down (both displayed). Good to know in practice. I realize that a lower green, let's say at only 120 yards, will not be impacted as much by elevation because of ball trajectory vs. a 220 yard pin with a different ball trajectory. Still fun.
Now for the caution, which I hope doesn't cause me to return this slope addition- - - still thinking. I use a SkyCaddie SGX for regular play. However, if I ever wanted to use a laser finder, this slope edition is OK for daily play . . BUT . . . you cannot use this device in any kind of tournament, even if you turn off the slope / plays-as distance feature. Thus, this slope edition is not tournament legal. Its less expensive counterpart, the V3 non-slope model includes jolt / pin seeker and is legal in any tournament where measuring devices are allowed (e.g. a SkyCaddie). I should have known this, but I missed this nuance on the V3 slope and V3 non-slope product pages. The V3 non-slope product page indicates "tournament legal." The V3 Slope product page doesn't indicate anything. For me, it would have been nice to have had the notation "not" tournament legal" explicitly indicated. Still, for fun travel to courses that have raised tees or those very low greens - vacation places - for fun play, this is a fun device. . . and for my primary goal of knowing true distances on hilly ranges, this is nice.
Re-cap. Excellent device. Couldn't be easier to use or quicker to display. Jolt indication worth buying the V3 product over the V2. The "V3 Slope" is a neat product, but it is not tournament legal (even if you turn off the slope feature). Will still use my SkyCaddie SGX for regular play because of the wealth of other information provided that I wouldn't want to be without. Will use this laser mostly at hilly practice ranges or if range is not in SkyCaddie(very rare these days). Before buying a laser, strongly consider the GPS golf devices, like SkyCaddie. IMO, a laser as an "additional" device makes sense, but not as your only golf device.
