What They Have in Common
Both sit at the same price point and target the same golfer: someone serious enough to spend $300 on a rangefinder but not chasing a flagship. Both lock onto the pin with some form of vibration feedback, and both offer water resistance for rounds when the weather doesn't cooperate.
Where They Differ
Accuracy and Optics
Here's where the V6 pulls ahead in ways that matter if you care about specs. Bushnell publishes its accuracy: ±1 yard at 500 yards, 6x magnification, IPX6 water resistance. Those are real numbers you can evaluate. Callaway's published specs for the CSi Pro are thin — magnification isn't listed, accuracy isn't listed, display type isn't listed. That's not necessarily a knock on the rangefinder itself, but it does mean you're going in with less information.
The V6's 6x magnification is solid. It's the same glass Bushnell has been refining for years, and it shows. The CSi Pro's multi-coated optics are mentioned in the feature list, which suggests decent lens quality — but "multi-coated" is also a phrase that shows up on a lot of optics at a lot of price points. Hard to weigh it against something you can't measure.
Slope and Club Selection
The CSi Pro has slope. The Tour V6 does not. That's not an oversight — it's intentional. The V6 is built to be tournament-legal out of the box, no switch required. You grab it, you go, and you never have to worry about whether slope is off or if you accidentally bumped something.
The CSi Pro takes a different angle. It has slope, and it layers a club-selection feature on top — so instead of just giving you a slope-adjusted yardage, it's suggesting which club to hit. Whether that's useful or annoying probably depends on where you are in your game. A 20-handicap who's still figuring out their distances might find it genuinely helpful. Someone who's already dialed in their wedges probably doesn't need a rangefinder making suggestions.
The slope switch is there if you need to go tournament-legal, which is fine — but the honest admission is you'll probably forget to flip it at least once.
Build, Weight, and Battery
The V6 weighs 8.7 oz. The CSi Pro is 5.6 oz — a meaningful difference if you're carrying and the rangefinder is in your pocket all round. Three ounces doesn't sound like much, but it is noticeable.
The V6 runs on a CR2 lithium battery. Those are at every pharmacy in the country, and they last long enough that most golfers change them once a season if that. Callaway doesn't publish battery type for the CSi Pro, so I can't make a direct comparison — that's a gap worth noting before you buy.
Water resistance: the V6 is rated IPX6, which means it can take a direct spray. The CSi Pro is listed as "water-resistant" without a rating. Probably fine for rain, but the V6's spec is more reassuring on that front.
Who Should Buy Which
Get the Tour V6 if:
- You play in club competitions or any rounds where slope-assisted devices are prohibited, and you want zero doubt about legality
- You want published accuracy specs you can actually evaluate before spending $300
- You're the golfer who plays the same course every week and has your yardages memorized — you just need reliable lock-on, not a caddie
- You value a known battery format (CR2) so you're never stranded mid-round wondering if the thing is going to die
Get the Callaway CSi Pro if:
- You're a 15-to-20 handicap still getting a feel for how far you actually hit each club, and a club-selection nudge would save you from the "well, maybe I can pull off a 6-iron here" decision
- You play casual rounds exclusively and slope is something you actively use on every approach
- Weight matters to you — 3 oz lighter is 3 oz lighter, and over 18 holes carrying a bag, that adds up
- You want slope functionality at a price that doesn't require stepping up to a pricier tier
The Bottom Line
The CSi Pro is a capable rangefinder with a feature set that'll appeal to a specific golfer. But the spec gaps are real — you're spending $299 on a device where magnification, accuracy, and battery type aren't published. The V6 gives you verifiable specs, tournament legality, and Bushnell's well-established optics at essentially the same price.
If they were further apart in price, the calculus might shift. At a dollar difference, I'd go with the one I can actually evaluate on paper.
Get the Bushnell Tour V6.
