The Quick Verdict
Get the GolfBuddy aimLITE S. At $99.99, it does everything most golfers actually need — slope, flag-lock vibration, tournament mode, and USB-C charging — for $150 less than the L6. The Voice Caddie L6 is worth considering only if you play a lot of twilight or low-light rounds where that OLED display genuinely earns its keep. Check price at Amazon →
What They Have in Common
Both rangefinders top out at 1,000 yards, have slope modes with a legal toggle for tournament play, and use vibration to confirm flag lock. Those are the core features most golfers care about day to day. Beyond that, the specs and price diverge pretty sharply.
Where They Differ
Price and What You're Getting for It
This is a $150 gap between two Tier 4 rangefinders, which is a lot to explain. The aimLITE S comes in at $99.99. The L6 is $249.99. For that difference to make sense, the L6 needs to deliver meaningfully better performance — not just a fancier spec sheet. Whether it clears that bar depends on which specs you actually care about.
Optics and Display
The aimLITE S has 6.5x magnification, the L6 has 6x. That half-step probably won't change your life, but the aimLITE S has the edge if you're comparing them directly. Where the L6 fights back is the OLED display. OLED screens produce sharper contrast and read better in dim conditions than standard LCD-style displays — if you're playing early morning rounds in the fall or finishing a round in fading light, the difference is real. GolfBuddy doesn't publish the aimLITE S's display type, so it's hard to make a direct comparison, but the L6's OLED is a concrete advantage in low-light situations.
Slope and Accuracy
Both units have slope mode with a tournament-legal switch. The L6 uses what Voice Caddie calls a "V-Algorithm" for slope calculation, and it publishes ±1 yard accuracy. GolfBuddy doesn't publish an accuracy figure for the aimLITE S, which isn't unusual at this price, but it does mean you can't make an apples-to-apples comparison. The L6 also has a "rapid-fire scan" feature for sweeping across multiple targets, which is handy on layup holes or when you're trying to find the front vs. back of a green.
Build and Charging
Here's where the aimLITE S picks up real-world points. It has a built-in lithium battery with USB-C charging and a magnetic mount included. USB-C matters — it's the same cable as most phones and earbuds at this point, so you're not hunting for a proprietary charger or a CR2 battery at a pro shop. The magnetic mount is a nice grab-and-go touch for cart riders. The L6, by contrast, is water-resistant (the aimLITE S has no published water resistance rating), but Voice Caddie doesn't publish battery life details, so you're a bit in the dark on that front. The aimLITE S also weighs 177g; the L6 comes in at 5.6 oz (about 159g), so they're close.
Who Should Buy Which
Get the GolfBuddy aimLITE S if:
- You want a capable slope rangefinder and don't want to spend more than $100 — this is a lot of feature for the money.
- You're the golfer who plays Saturday mornings in bright conditions and just needs fast, reliable yardages.
- You appreciate USB-C charging and a magnetic mount included in the box without paying a premium for them.
- You play the occasional tournament and want the slope-switch without worrying about overspending on a unit you'll have to babysit at the cart.
Get the Voice Caddie L6 if:
- You regularly play early morning or late-afternoon rounds where a sharper OLED display would actually make a difference — the golfer finishing 18 in September with the sun dropping behind the trees will notice it.
- You want published accuracy specs and a rapid-fire scan for bouncing between targets on approach shots.
- Weather is a real concern and water resistance matters to you — the aimLITE S has no published rating, the L6 does.
- The $150 gap doesn't move the needle for you and you want the premium build.
The Bottom Line
The L6 is a good rangefinder. The OLED screen, water resistance, and published accuracy are all legitimate wins. But the aimLITE S does the 90% of rangefinder work that matters — slope, flag lock, legal tournament mode, rechargeable battery — for $150 less. That's one and a half rounds of green fees, depending on where you play. For most golfers, the aimLITE S is the call. The L6 makes sense if low-light display quality or weather protection are things you'd actually use, not just nice to have on a spec sheet.
