The Quick Verdict
Get the Blue Tees Series 3 Max+. At $200 vs $250, it's $50 cheaper than the L6, and it gives you more transparency about what you're actually buying — published battery specs, a USB-C rechargeable system, and explicit waterproofing ratings. The Voice Caddie L6 only makes sense if you specifically want an OLED display and don't mind paying a premium for a device where Voice Caddie hasn't published the battery life.

What They Have in Common
Both are 6x rangefinders with 1,000-yard range, ±1-yard accuracy, slope modes with a tournament-legal switch, and vibration feedback on flag lock. They're sitting in the same tier for a reason — neither is cutting corners on the basics, and either one will get you a confident yardage on an approach shot.
Where They Differ
Display
This is the one place where the L6 makes a genuine case for itself. OLED screens have better contrast and tend to read more cleanly in low light — early morning rounds, overcast days, deep shadow on a tree-lined par 3. The Blue Tees uses an LCD with what the brand calls "red/black HD colour control," which lets you toggle the display color for visibility. That's a nice touch, but it's a workaround for a problem OLED doesn't have in the first place. If you're someone who plays a lot of dawn patrol rounds, the L6's screen is legitimately better for that.
Battery and Charging
The Series 3 Max+ publishes its battery spec: 1,000 mAh, good for roughly 50 rounds per charge, with USB-C top-up. That's a meaningful number. You know what you're getting and you can plan around it. The L6's battery life is not published, which isn't necessarily a red flag — plenty of rangefinders outlast their specs in practice — but it does mean you're buying on faith. USB-C is genuinely useful, too. CR2 batteries are everywhere, but having a rangefinder that charges like your phone means one fewer thing to think about.
Water Resistance
The Series 3 Max+ is IPX4 rated, which means it's been tested to handle splashing from any direction. That's a real standard with a real test behind it. Voice Caddie describes the L6 as "water-resistant" without a rating. Could be fine. Could be the same protection under a different label. But when you're deciding between two similarly-specced rangefinders, I'd rather have the number than the marketing language.
Build and Feel
The Blue Tees comes in at 220g with a magnetic mount included. The L6 weighs 5.6 oz (roughly 159g), so it's noticeably lighter in hand — about 60g difference, which you'd actually feel. Voice Caddie doesn't publish dimensions for the L6, so comparing form factor precisely isn't possible. The lighter weight is a real point in the L6's favor if you're someone who carries (rather than rides) and is conscious of bag weight.
Who Should Buy Which
Get the Blue Tees Series 3 Max+ if:
- You want a rechargeable rangefinder and USB-C charging is easier to work into your routine than carrying spare batteries
- You play in rain or morning dew regularly and want an actual IPX4 rating rather than a vague "water-resistant" claim
- You're the golfer who carries the bag yourself five days a week and wants to know your equipment specs upfront — 50 rounds per charge, ±1 yard, IPX4 — before you buy
- You'd rather put the $50 savings toward range balls or a new wedge than pay a premium for specs that aren't fully disclosed
Get the Voice Caddie L6 if:
- You play a lot of early morning rounds in dim light and the OLED display is genuinely worth $50 to you — it does read better in those conditions
- You prefer lighter gear and 60g less in your hand or bag matters over the course of a round
- You've used Voice Caddie products before and trust the brand enough that unpublished battery specs don't bother you
- You want the rapid-fire scan mode for checking multiple distances quickly during practice or course management
The Bottom Line
These two rangefinders are close, and the L6 isn't a bad device — the OLED display and lighter weight are real. But paying $50 more for a rangefinder where the battery life is unpublished and the water resistance is uncertified is a tough sell when the cheaper option gives you those answers directly. The Series 3 Max+ is transparent about what it is, it charges over USB-C, and it costs less.
