The Quick Verdict
Get the Nikon COOLSHOT 20i GIII. It's $60 cheaper, it has slope, it weighs half as much, and the five-year warranty covers the price gap before you even think about it. The Tour V6 is worth it in one specific case: you're playing USGA tournaments regularly and need a no-slope device right out of the box, no switch required. Check price at Amazon →
What They Have in Common
Both use 6x magnification and CR2 lithium batteries, so you're not giving up optical zoom or scrambling for obscure batteries with either one. Both are accurate to ±1 yard at reasonable distances, and both will lock onto a flag with enough reliability to trust for approach shots. That's the baseline — anything above it is where they split.
Where They Differ
Slope and Tournament Legality
This is the whole ballgame. The Tour V6 has no slope at all — it's a pure distance device, legal for tournament use without any switches or settings to manage. The COOLSHOT 20i GIII has slope with a slope-switch to toggle it off when you need tournament mode. If you've used a slope-switch before, you know the drill: you'll toggle it off the night before your club championship and forget to toggle it back on for a month of casual rounds. That's not a knock on Nikon specifically — it's just how slope switches work in real life. But for 95% of rounds, you want slope, and the COOLSHOT has it.
Accuracy and Range
The Tour V6 is rated to ±1 yard out to 500 yards and has a maximum range of 1,300 yards. The COOLSHOT 20i GIII is ±1 yard to 100 meters (roughly 109 yards), then ±2 yards beyond that. For a par-4 approach shot from 160 yards, you'll never feel the difference. Being off by a yard at 200 yards doesn't change your club selection. Where it might matter is extreme distances — but you're not actually flagging across 500 yards in a real round, so Bushnell's ceiling is mostly a spec sheet number.
Size and Feel
Here's where the COOLSHOT 20i GIII makes a quiet argument that's easy to underestimate: it weighs 4.6 ounces. The Tour V6 weighs 8.7 ounces — nearly twice as much. The Nikon also physically pockets more easily based on its dimensions. If you're walking and carrying, or just don't want a rangefinder that feels like a small brick in your pocket by the back nine, that weight difference is real. The BITE magnet on the Tour V6 is genuinely useful for cart golfers — quick grab off the cart rail without fussing with a case — but it doesn't help you if you're on foot.
Water Resistance and Warranty
IPX6 (Tour V6) versus "rainproof" (COOLSHOT 20i GIII). IPX6 is a defined standard: it can handle sustained water jets. Rainproof is vaguer, but in practice it means you're fine in a light-to-moderate shower. Both will survive a normal round in the rain. One won't survive a full drop into a water hazard — I'd keep both dry on principle.
The COOLSHOT's five-year warranty is the detail that sneaks up on you. Most rangefinders in this price bracket carry one or two years. Five years is a meaningful statement from Nikon about how long they expect the unit to hold up.
Who Should Buy Which
Get the Nikon COOLSHOT 20i GIII if:
- You play the majority of your rounds casually or with your regular group, and you want slope-adjusted yardages without overthinking it
- You're a walking golfer who carries a bag — 4.6 ounces versus 8.7 ounces adds up over 18 holes
- You want a rangefinder that fits properly in a shorts pocket, not just a bag pocket
- You're buying something you expect to own for several years — the five-year warranty is a legitimate differentiator at this price
Get the Bushnell Tour V6 if:
- You compete in USGA-sanctioned events frequently enough that a slope-switch feels like a liability — something that could cost you a hole if you forget to flip it
- You regularly range very long targets (250+ yards to a landmark, 400-yard hole yardages off the tee) and want the extra precision the Tour V6 is rated for
- You ride in a cart most of the time and the BITE magnet is genuinely useful to your routine
The Bottom Line
Sixty dollars separates these two, and the cheaper one has slope, a lighter build, and a longer warranty. The Tour V6 is a good rangefinder — Bushnell's accuracy reputation is well-earned — but without slope mode, you're paying more for less functionality unless tournament legality is a real, recurring need in your life. The Nikon isn't trying to be a premium Tour device. It's trying to be the most useful rangefinder most golfers will ever use, and it mostly succeeds.
