Bushnell A1-Slope vs Garmin Approach Z82

The Quick Verdict

These two are not really in the same conversation. The Garmin Approach Z82 is a $599.99 hybrid GPS-laser device that overlays course maps in your viewfinder. The Bushnell A1-Slope is a $299.99 pocket rangefinder that does one thing — measures distances accurately — and fits in your shirt pocket. If you want a rangefinder with GPS course data baked in, get the Z82. If you want a clean, fast, accurate laser that goes everywhere with you and costs half as much, get the A1-Slope.

What They Have in Common

Both are 6x magnification, both have slope mode with the ability to toggle it off for tournament play, and both are USB-C rechargeable (no CR2 batteries to chase down mid-round). That's a meaningful overlap — rechargeable units have gotten reliable enough that battery anxiety is mostly off the table. Accuracy on both is strong enough that you're not leaving shots to the rangefinder. That's table stakes at these price points.

Where They Differ

What You're Actually Looking Through

This is the whole game. The Bushnell A1-Slope uses a standard LCD display — clean, readable, fast. You point at the flag, you get a number. The Garmin Z82 projects a full-color 2D course map overlay into the viewfinder alongside the laser reading. You're looking at hole layout, hazard distances, and a laser range arc simultaneously. That's a genuinely different experience, not just a spec upgrade. Whether it's better depends entirely on how you use that information on the course.

The Z82 also pulls wind data through the Garmin Golf app, which is a feature I'd expect more on a launch monitor than a rangefinder — but here we are. My read is that it's most useful for golfers who are already tracking shots and rounds through the app anyway. If you're not in that ecosystem, it's probably an afterthought.

Range and Accuracy

The A1-Slope reaches out to 1,300 yards with ±1 yard accuracy at 350 yards. The Z82 maxes out at 450 yards to the flag. That sounds like a major gap until you realize 450 yards covers every realistic shot on any golf course — even the longest par-5s won't need more. The accuracy spec on the Z82 is listed as within 10 inches at the pin, which is frankly tighter in practice. Both are more than accurate enough that you can't blame the rangefinder when you come up short.

Size and Portability

The A1-Slope earns its "smallest Bushnell ever" claim — 3.75 × 1.42 × 2.36 inches and 5.1 ounces. That fits in a shirt pocket without pulling the fabric sideways. Garmin hasn't published weight or dimensions for the Z82, which tells you something. Probably because it's not a pocket unit. It's a device you clip to the bag or drop in the cart — that's not a knock, it's just a different form factor.

Water Resistance

The Z82 is IPX7 — submersible to one meter for 30 minutes. The A1-Slope is IPX6, which means sustained heavy spray but not submersion. For golf, IPX6 covers rain, dew, and the occasional dunking in your bag's drink holder. IPX7 is a real step up if you play in genuinely nasty conditions or are hard on gear.

Battery Life

Fifty-plus rounds on the A1-Slope is exceptional for a rangefinder. The Z82 gives you up to 15 hours in GPS mode — a different measurement because GPS is always running. Both will comfortably last multiple rounds between charges, so this one's a wash for most golfers.

Who Should Buy Which

Get the Bushnell A1-Slope if:

• You want a fast, lightweight laser you can palm, slip in a pocket, and forget about between shots
• You play in tournaments and need a clean slope-switch toggle without fishing through menus
• You're the golfer who just wants a reliable number and doesn't need a course map in the viewfinder
• The scenario: You play three different courses in your rotation, you don't track stats digitally, and you want one compact rangefinder that lasts for years without overthinking it

Get the Garmin Approach Z82 if:

• You're already using Garmin Golf to track rounds and want your rangefinder integrated into that data
• You want hole layout and hazard distances visible while you're ranging — not as a separate step, but simultaneously
• You play courses where knowing the full hole picture (layup distances, carry distances to hazards) changes your club selection
• The scenario: You're a 12-handicap who's genuinely course-managing — thinking about where to miss, what the bailout is — and you want all that information in one look instead of juggling a GPS watch and a rangefinder

The Bottom Line

Three hundred dollars is a real gap. The Z82 earns it with a feature set that's legitimately different — not just better optics, but a different category of tool. If you're the golfer who will use the GPS overlay and the app integration on every round, it's worth it. If you're not already living in that ecosystem, you're paying for software you'll ignore. The A1-Slope is accurate, tiny, rechargeable, and $300 cheaper. For most golfers, that's the right call.

Get the Bushnell A1-Slope.
