The Quick Verdict
Get the Shot Scope PRO L5. It's $70 cheaper, has 7x magnification to the A1-Slope's 6x, and that OLED display is a genuine upgrade over the A1-Slope's LCD — and those are the things you actually use every time you pull the trigger. The A1-Slope is worth a look only if pocket size is a hard requirement and you'd genuinely use the USB-C charging. Check price at Shot Scope →
What They Have in Common
Both rangefinders hit ±1 yard accuracy, top out at 1,300 yards, and have slope with a legal-play switch — so you can toggle it off for competition rounds. Both have a magnetic mount so you can stick them to a cart. The foundational stuff is matched. This comparison lives in the details.
Where They Differ
Optics and Display
Here's the thing: the display is what you're staring at for four hours. The PRO L5 uses an OLED panel; the A1-Slope uses LCD. Shot Scope calls this OLED its sharpest display yet. I haven't looked through either, but I'd bet on an OLED over an LCD in bright midday glare or flat grey light. Nobody reads a rangefinder in full sunlight; they read it in the shade of their hand.
The PRO L5 also has 7x magnification versus the A1-Slope's 6x. One extra power doesn't sound like much, but it makes the flag bigger in the frame on a long approach. The PRO L5 also adds pulse vibration to confirm target acquisition, which the A1-Slope doesn't have — a small thing, but I'd guess you'd miss it once you're used to it.
Size and Weight
This is where the A1-Slope genuinely earns its price. Bushnell calls it their smallest rangefinder ever, and at 5.1 oz and just under 4 inches long, it's noticeably compact. The PRO L5 weighs 12 ounces and is almost an inch longer — more than twice the weight. If you carry your bag and live by a "less in my pockets" policy, that's real. Bushnell bills the A1-Slope as pocket-size; the PRO L5, at 4.6 × 1.6 × 2.8 inches, makes no such claim.
Battery Setup
The A1-Slope is USB-C rechargeable and rated for 50+ rounds on a charge. That's excellent longevity, and USB-C means you're charging it with the same cable as your phone. The PRO L5 runs on a CR2 3V battery rated for around 5,800 measurements. How long that lasts depends on how many shots you range per round, but the key point is you're carrying a spare and swapping batteries, not plugging in.
CR2 batteries are at every pharmacy in the country, which matters more than it sounds when you're playing away from home and the battery dies Tuesday morning. Rechargeables are cleaner but dependent on you remembering to charge them.
Value at This Price
At $229.99, the PRO L5 delivers more magnification and an OLED display for $70 less than the A1-Slope. That's a hard gap to argue against. The A1-Slope's premium is essentially paying for miniaturization, which is a real thing — but for most golfers, it's not the most important thing.
Who Should Buy Which
Get the Shot Scope PRO L5 if:
- You want 7x magnification and an OLED display without paying a premium for it
- You're the golfer who tees off at 6:30am in October and would bet on an OLED over an LCD in that flat grey light (I would)
- You'd rather carry a spare CR2 than think about charging before every round
Get the Bushnell A1-Slope if:
- You carry your bag and genuinely count ounces — 5.1 oz vs 12 oz is nearly 7 oz you don't have to carry
- USB-C charging fits your routine and you want one less battery type to stock
- You want the smallest unit for a pocket — 3.75 × 1.42 × 2.36 in against the PRO L5's 4.6 × 1.6 × 2.8 in
The Bottom Line
The PRO L5 is the better rangefinder at the lower price. OLED display, 7x magnification and pulse vibration — all for $70 less than the A1-Slope. The A1-Slope isn't bad; it's just more expensive for fewer features, and the trade you're making is size and weight, which matters only if you're a dedicated walker who's serious about what goes in your pockets. For the rest of us, that's not the trade.
