What They Have in Common
Both shoot at 6x magnification and claim ±1 yard accuracy — at close range, at least. Both run on CR2 lithium batteries (easy to find, good to know). Both have some form of pin-acquisition feedback to confirm lock. That's about where the overlap ends. These are genuinely different products aimed at different use cases.
Where They Differ
Slope — and Whether That Matters to You
This is the clearest difference. The Nikon has slope. The Bushnell doesn't. If you play casual rounds and want adjusted yardages for elevation change, the Nikon gives you that. The Bushnell Tour V6 is built specifically for tournament-legal use — no slope, no grey area. It's worth noting that the Nikon does have a slope-switch, meaning you can toggle slope off, but even with it disabled, many competitions don't allow devices that have slope capability, depending on the governing body and the local rule in play. If you're playing serious amateur events, check your rulebook. The V6 doesn't make you check anything.
Accuracy and Range
Both claim ±1 yard, but the fine print diverges. The Nikon's ±1 yard spec applies only within 100 meters — beyond that it's ±2 yards. The Bushnell holds ±1 yard out to 500 yards. For most approach shots that won't matter, but if you're dialing in a 220-yard carry over water, you'd rather have the tighter number. The V6 also has a significantly longer range ceiling — 1,300 yards to the Nikon's 800 — though neither of us is ranging anything at 1,300 yards in a real round.
Weight and Form Factor
The Nikon is 4.6 oz. The Bushnell is 8.7 oz. That's not a small gap — the Nikon is essentially half the weight. If you carry your bag, that difference is real over 18 holes. The Nikon's dimensions are also genuinely compact; it fits in a shorts pocket without the bulk you'd notice. The Bushnell is a full-size rangefinder. Neither is wrong, but if you want something you forget is in your pocket, the Nikon wins easily.
Water Resistance and Build
The V6 is IPX6 rated — that's sustained water jets, not just drizzle. The Nikon is listed as rainproof, which is a softer claim. Probably fine for most conditions, but if you regularly play in real weather or toss your gear in a wet bag without thinking about it, the V6 is built for more abuse.
Warranty
The Nikon ships with a 5-year warranty. Bushnell's warranty terms aren't listed in the spec data here, so I won't guess — but the Nikon's 5-year coverage is a meaningful differentiator, especially at a lower price point. Seems like Nikon is using that warranty to offset some of the brand confidence gap against Bushnell.
Who Should Buy Which
Get the Bushnell Tour V6 if:
- You play in club championships, state amateurs, or any event where the local rule specifically requires a non-slope device — the V6 is clean, no toggles required
- You play early mornings in October when dew is everywhere and you want IPX6 confidence, not "rainproof"
- You want the longer-range accuracy spec for big-hitter courses with long approach yardages
- You're the golfer who leaves gear in the car, takes it out in the rain, and doesn't baby it
Get the Nikon COOLSHOT 20i GIII if:
- You carry your bag and 4 ounces genuinely matters over a hilly 18 — the Nikon won't fatigue your pocket
- You play casual rounds with your regular group and want slope-adjusted yardages without paying the premium that usually comes with them
- You're a 20-handicap who wants a reliable, accurate rangefinder at a fair price and doesn't need tournament credentials
- You value a 5-year warranty as real peace of mind on a $220 purchase
The Bottom Line
The $80 price gap is real, but these aren't competing for the same buyer. The Bushnell Tour V6 is the right call if tournament legality or build quality in wet conditions is part of your life. The Nikon COOLSHOT 20i GIII is the right call if you want slope, you carry your bag, and you're not playing for a trophy. If you're a casual player reading this, honestly, the Nikon is the better fit for most rounds most people play. But if you compete, don't cut corners on legality.
Get the Nikon COOLSHOT 20i GIII.
