The Quick Verdict
This one genuinely depends on how you play. If you want a clean, wrist-based distance solution that shows you full hole maps, hazard yardages, and dogleg info without pulling anything out of your pocket, get the G6 — especially at $149.99 on sale. If you want dead-accurate pin distance for approach shots and don't care about course navigation, the PRO ZR at $299.99 is the better single tool. But honestly, the most interesting answer here is that both together is a very real option for the right golfer. Same brand, same app, and together they cover everything a GPS watch can't and everything a rangefinder can't.
What They Actually Do
The G6 is a wrist GPS watch that shows you distance to the front, center, and back of the green, full hole maps on 36,000+ courses, and hazard/layup yardages — all from a glance at your wrist. The PRO ZR is a laser rangefinder that you point at a target and it tells you exactly how far away it is, within one yard. Both are Shot Scope products, both live in the Shot Scope app, and both are legal for tournament play (with slope disabled on the PRO ZR).
The Real Tradeoffs
Precision vs. Convenience
The PRO ZR wins on accuracy to a specific point. It's ±1 yard to wherever you aim it — the flag, a bunker lip, a tree you're trying to lay up short of. The G6 gives you distances to fixed green reference points (front/center/back), which is accurate enough for most club decisions but won't tell you the flag is cut 8 yards from the back edge today.
That said, most golfers overestimate how often pin-precise distance actually changes their club. If the front is 155 and the back is 175, you know your 7-iron to center is a 165-yard shot. The G6 gives you that. Where the PRO ZR earns its keep is on that tucked back-left pin where three extra yards is the difference between a birdie putt and the bunker.
Speed of Use
Standing on the tee or picking a layup yardage? The G6 is just there. You glance down and you have everything you need. The PRO ZR means fishing it out, steadying it, finding the target, pressing the button, reading the display, putting it back. Over 18 holes, that adds up — especially if you're playing with pace-of-play pressure.
Where the rangefinder wins on speed is for golfers who already know what they want to know and just need the number confirmed. If you're 160 out and you want to know the exact pin distance, the PRO ZR gets you that number in a couple of seconds. The G6 can't get you closer than a front/center/back split.
What You Can See Before You Swing
This is the G6's biggest advantage and a category-level difference the PRO ZR can never close. You're on a tee box you've never played — 410-yard par 4, dogleg right, water hugging the left side. The G6 shows you the whole hole: where the water starts, the carry to clear it, how far to the dogleg. You know to take 5-iron off the tee before you ever step into your shot.
Point the PRO ZR at anything and you get a number. But there's nothing to point at until you already know what you're looking at. Course navigation isn't what it's built for.
Information Depth
The G6 does a lot more than distance. Full hole maps, hazard yardages, dogleg distances, digital scorecard — it's a course management tool. The PRO ZR does one thing: measure the distance to whatever you aim at. That's it. One number per trigger pull. But that one number is more accurate than anything the watch provides, and for golfers who live and die by exact yardage to the pin, that matters more than 15 other features they don't use.
The Shot Scope Ecosystem
Since these are both Shot Scope products, worth mentioning: they share the Shot Scope app. If you own both, your round data is all in one place. The G6 handles scoring and course navigation on-course; the PRO ZR handles pin precision. They're not marketed as companion devices that sync in real time, so don't expect the rangefinder reading to pop up on your wrist. But they're built around the same platform, which keeps things cleaner than mixing brands.
Cost of Play
G6 is $149.99 on sale, $179.99 MSRP — no subscription required, free course updates. PRO ZR is $299.99. Neither has an ongoing cost, which is genuinely nice. If you're considering both, you're looking at roughly $450 total, which is real money but not outrageous for a full distance solution. Both use the discount code PARANDPEG for 15% off at Shot Scope directly.
Tournament Play
G6 is tournament legal as-is — it has a tournament mode built in. The PRO ZR has a slope switch, so you flip it off, slope is disabled, and you're legal. No issues with either.
Who Should Get Which
Get the G6 if you want an always-on wrist device that handles course navigation, hazard yardages, and scoring without ever reaching into your bag. You play different courses regularly, you like knowing the hole layout before you swing, or you just want one clean solution and you don't need exact pin distances to play well. At $149.99, it's also the easier decision financially.
Get the PRO ZR if you already know your home courses cold — the layouts aren't the problem, you just want exact pin distance on approach. You prefer single-purpose tools, you'd rather spend money on precision than features, or you're the type who genuinely uses slope-adjusted distances in practice rounds.
Get both if you're a mid-to-low handicap player who wants the full picture: hole strategy from the watch, exact pin distance from the rangefinder for approach shots. The G6 on your wrist handles everything from tee to 100 yards out; the PRO ZR handles the precision work on approach. Together they don't overlap much — they actually cover each other's blind spots.
The Bottom Line
The G6 is a genuinely solid GPS watch for the price, and the PRO ZR is a precision laser that does its one job extremely well. If budget is the deciding factor, the G6 at $149.99 gives you more versatility for less money. If pin-accurate yardage is the thing you care most about, the PRO ZR wins. But for the golfer who wants to stop guessing on approach shots AND see the full hole before they hit?
Get both. The G6 on your wrist, the PRO ZR in your pocket.
