The Quick Verdict
Get the Shot Scope PRO L5. For $20 less, you get better magnification, a longer range and a stated battery life — the L6 doesn't clearly beat it on anything that changes your round. The Voice Caddie L6 is worth considering only if you specifically want the Pin Tracer feature and that's a dealbreaker for you. Check price at Shot Scope →
What They Have in Common
Both are water-resistant OLED rangefinders with slope mode and a slope switch (legal for tournament play), ±1 yard accuracy, and rapid-fire scanning. The display tech and core shot-measurement experience are comparable — you're not choosing between a good screen and a bad one, or between slope and no slope.
Where They Differ
Magnification and Range
This is probably the most practical difference. The PRO L5 gives you 7x magnification; the L6 is 6x. That extra magnification genuinely helps on longer par-5s when you're trying to lock onto a flag that's 250 yards away and looks like a toothpick. It doesn't matter much for a 140-yard approach, but when you need it, you notice it.
The range spec gap is even wider: 1,300 yards vs. 1,000 yards. Honestly, neither of us is ranging targets at 1,300 yards in a real round — but the gap hints at the underlying optics quality, and the PRO L5 is the stronger unit by that measure.
Weight and Form Factor
Here's a real-world difference that doesn't get enough attention: the L6 weighs 5.6 oz. The PRO L5 weighs 12 oz — more than twice as much. That's a significant difference you'll feel in your shirt pocket or cart bag pocket over 18 holes. Voice Caddie doesn't publish the L6's dimensions, so I can't give you a full size comparison, but if carrying a lighter rangefinder matters to you, the L6 has a genuine edge there.
Battery and Warranty
The PRO L5 runs on a CR2 battery — replaceable at any pharmacy in the country, with a rated life of about 5,800 measures. That's a number you can plan around. Voice Caddie doesn't publish a battery life figure for the L6 at all, which makes it harder to know what you're getting into. It may be totally fine, but you can't know going in.
On warranty, Shot Scope backs the PRO L5 with two years. I couldn't confirm Voice Caddie's warranty for the L6.
Shot Scope's Extra Features
The PRO L5 includes a strong magnet mount and pulse vibration confirmation. Voice Caddie has vibration too, but Shot Scope's magnet is spec'd as notably strong — useful if you're mounting it to a cart bar or bag clip and don't want to chase it across the cart path. The L6 counters with Pin Tracer, which is designed to help lock onto the flag faster in cluttered backgrounds. That's a real feature, not marketing fluff. It just doesn't outweigh everything else the PRO L5 brings.
Who Should Buy Which
Get the Shot Scope PRO L5 if:
- You want a rangefinder with a battery you can replace mid-trip without hunting for a specialty charger
- You play longer courses where being able to lock in at 250+ yards with 7x magnification actually comes up
- You're mounting your rangefinder to a cart and want a magnet that's going to hold
- You'd rather spend $20 less and get more documented specs to compare
Get the Voice Caddie L6 if:
- You carry your bag and genuinely notice weight — going from 12 oz to 5.6 oz is enough of a difference to matter over a hilly walking course
- Pin Tracer is something you've specifically tried and liked, and you find traditional flag acquisition frustrating on busy backgrounds
- You've had good experiences with Voice Caddie products before and trust the brand
The Bottom Line
These are priced within $20 of each other, so this should be an easy call based on features — and it is. The PRO L5 has better magnification, longer stated range and a named battery with a published life. The L6 is lighter and has Pin Tracer, but that's a thin trade for what you're giving up. If the L6 were $50 cheaper, the weight advantage might tip it. At $20 more, it doesn't.
