The Quick Verdict
Get the Callaway CSi Pro. It's $100 cheaper, has slope, and at 5.6 oz it's noticeably lighter than the Tour V6's 8.7 oz — that's a meaningful difference when it's riding in your pocket for four hours. The Tour V6 earns its place if you play in tournament conditions regularly and want the assurance of a Bushnell on the bag, but for most rounds at most courses, the CSi Pro does more for less.
What They Have in Common
Both are 6x magnification LCD rangefinders with ±1 yard accuracy and water resistance. They'll lock onto a flag at similar distances and give you a number you can trust. Neither is a budget unit — both sit in the same tier and both carry enough glass quality to read yardages cleanly in normal playing conditions.
Where They Differ
Slope and Course Management
This is the biggest functional gap between these two. The CSi Pro has slope — the Tour V6 does not. Slope-adjusted yardage isn't just a nice-to-have on hilly courses; it genuinely changes club selection, especially on approach shots with significant elevation change. The CSi Pro also includes what Callaway calls CSi Club Selection, which pairs the slope-adjusted distance with a club recommendation. You can ignore the club suggestion if you want (plenty of golfers will), but having slope at all puts the CSi Pro in a different category for everyday play.
The Tour V6 is tournament-legal without any mode switching. That's its play. No slope chip means no slope, which means no disqualification risk if you accidentally leave a mode enabled. For golfers who compete often, that simplicity has real value. For everyone else, it's a feature you're paying for and not using.
Weight and Feel
Three ounces doesn't sound like much on paper. It's about 35% more weight, and you notice it. The Tour V6 at 8.7 oz feels substantial in hand — solidly built, deliberately so. The CSi Pro at 5.6 oz is genuinely pocketable in a way the V6 isn't quite. If you walk and carry your bag, lighter matters more than people admit.
Lock-On and Feedback
Bushnell's PinSeeker with Visual Jolt gives you a physical buzz and a visual ring when it locks the flag — it's one of the cleaner implementations of flag-lock feedback in the category. The CSi Pro uses PAT (Pin Acquisition Technology) with vibration confirmation, which is a similar idea. Both work. Bushnell's been doing this longer and the Visual Jolt is well-regarded, but the CSi Pro's implementation is solid enough that it's not a deciding factor for most buyers.
Battery and Water Resistance
The Tour V6 runs on a CR2 lithium battery — a standard size you can find at any pharmacy. That's a real-world advantage: if you're mid-round and your rangefinder dies, CR2s are not hard to locate. The CSi Pro's battery life isn't published, which is a small knock against it. You'd hope Callaway publishes that somewhere in the box, but not knowing the spec makes it harder to compare. The Tour V6 is also rated IPX6, a defined waterproof standard. The CSi Pro is listed as "water-resistant" without a rating — probably fine for rain, but you don't know exactly where the line is.
Who Should Buy Which
Get the Callaway CSi Pro if:
- You play most rounds casually and want slope-adjusted yardage for everyday club selection — this is the majority of golfers.
- You're the 12-handicap who switches courses regularly and wants a club suggestion to sanity-check before you pull iron.
- Weight is a real consideration — you walk 18 holes with a carry bag three or four times a week.
- You want to spend $199 instead of $299 and keep the savings for something else.
Get the Bushnell Tour V6 if:
- You play competitive rounds with a handicap index and enter tournaments where rangefinders are legal but slope is not — the V6 removes any toggle-related risk.
- You've been burned by rangefinder battery drama before and want the peace of mind that CR2s are everywhere.
- You prefer a larger, more substantial feel in hand and find lighter units harder to hold steady.
- You're already in the Bushnell ecosystem and trust the brand's optics reputation.
The Bottom Line
The CSi Pro wins this on value and practical features. Slope is genuinely useful, it's lighter, and it's $100 less. The Tour V6 is built well and the tournament-legal-out-of-the-box design is legitimately convenient for competitive players — but that's a narrower use case than Bushnell probably wants to admit. For the golfer who plays weekend rounds and wants a reliable, slope-enabled rangefinder without overpaying, the choice here isn't close.
