What They Have in Common
Both land at essentially the same price, both shoot to ±1 yard accuracy, and both run on a single CR2 lithium battery. They share 6x magnification and magnetic mounts — the Blue Tees ultra-magstrip and Bushnell's BITE magnet both clip to a cart rail without digging around in your bag. Either one will dial in your yardages fast enough that you can't blame the rangefinder when you pull a nine-iron on a 150-yard shot.
Where They Differ
Slope — and Why This Is the Whole Conversation
The Series 4 Ultra has slope with a legal switch that lets you toggle it off for competition. The Tour V6 has no slope at all. This is the central difference, and it's a real one. If you play casual rounds most of the time and want adjusted yardages to help you club up on uphill par 3s, the Blue Tees wins this entirely. The Tour V6's argument is the flip side: no slope means no compliance headaches, no forgetting to switch it off before you tee off, and a cleaner experience if you play in leagues, club events, or any stroke play with officials watching. You'll toggle slope off for tournaments. You'll probably forget. The Tour V6 solves that by not having the problem.
Display
The Series 4 Ultra runs an OLED screen with manual brightness control. The Tour V6 uses LCD with Bushnell's PinSeeker Visual Jolt — a ring that flashes when it locks the flag. OLED is genuinely easier to read in low-contrast conditions: overcast mornings, deep tree shadows, late-afternoon rounds when the light goes flat. LCD in direct sun can wash out. That said, nobody reads a rangefinder in real sunlight; they read it in the shade of their palm. The OLED gap is real but probably smaller in practice than spec sheets suggest.
Water Resistance
IPX6 vs. IP54 is a meaningful gap. IPX6 means the Tour V6 can take sustained, heavy rain — the kind where you're debating whether to finish the back nine. IP54 means the Series 4 Ultra handles splashes and light rain without issue, but it's not rated for a downpour. If you play in the Pacific Northwest or routinely tee off in October when the weather turns genuinely ugly, this matters. For most fair-weather golfers in drier climates, IP54 is plenty.
Brand and Build
Bushnell has been the rangefinder brand on tour for years and the Tour V6 carries that lineage. Blue Tees has closed the gap considerably at this price point — the Series 4 Ultra is a legitimate rangefinder, not a budget substitute — but Bushnell's optics reputation and long-term reliability record are still real. Seems like Bushnell earns a small premium on trust alone, which makes the $0.99 price difference almost funny. They've basically landed at the same MSRP through different routes.
Who Should Buy Which
Get the Blue Tees Series 4 Ultra if:
- You play mostly casual rounds where slope-adjusted yardages actually change how you club
- You're the 12-handicap who plays early morning weekend rounds and wants that OLED screen to pop when the light isn't cooperating
- You want the most features for the dollar — slope, OLED, brightness control — and play in conditions where IP54 is sufficient
- You're newer to rangefinders and want the extra data slope provides while you're still building course management instincts
Get the Bushnell Tour V6 if:
- You compete in club championships, league play, or any events where slope is illegal — and you want the issue off the table permanently
- You're the 6-handicap who plays Saturday stroke play, Sunday scrambles, and a member-guest in the fall, and you don't want to think about compliance
- You play in real rain and need IPX6 confidence rather than splash-resistant
- You trust brand reputation and want a rangefinder with Bushnell's service history behind it
The Bottom Line
For most golfers at this price point, the Blue Tees Series 4 Ultra is the better buy. Slope matters for everyday rounds, the OLED display is a genuine upgrade, and it's a dollar cheaper. But "most golfers" isn't everyone. If competition rounds are a regular part of your schedule and slope is more hassle than help, the Tour V6 is the cleaner tool — and Bushnell's track record is worth something. The honest close-call here is this: if you compete, get the Bushnell. If you don't, get the Blue Tees.
Get the Blue Tees Series 4 Ultra.
