What They Have in Common
Both are no-subscription GPS devices with 38,000–40,000 preloaded courses, free updates, slope on/off toggle, manual shot distance tracking, and hazard distances. Neither has health tracking, smart notifications, or heart rate monitoring. Both are water-resistant. Both connect without a monthly fee.
Where They Differ
Screen and Interface
This is the biggest gap. The Ion Elite has a 1.28-inch color touchscreen — you tap the screen to place the pin, tap any point on the hole map for a precise distance, and navigate with your fingers. The GB VOICE 3S+ has a monochrome 128x64 pixel LCD and no touchscreen — buttons only, and the display is roughly the resolution of a basic pedometer from 2008.
More meaningfully: the Voice 3S+ has no green view, no hole maps, nothing visual beyond a yardage number. The Ion Elite shows you the shape of the green, lets you drag the pin to the actual hole location, and displays a top-down view of the hole with layup distances. If you play courses you don't know, that visual context matters more than people give it credit for. Looking at a number and looking at a hole map are different experiences.
The Voice Feature
The VOICE 3S+ does something the Ion Elite can't: it announces yardages out loud. Front, center, back — spoken to you, in your language (11 languages, 10 voice options including male and female). You clip it to your bag or belt, and it calls out the distance as you walk up. No glancing down, no wrist raise, no button press.
That's a genuinely useful feature if you're the golfer who'd rather keep their eyes on the course. It's not a gimmick. But it's also the only distinctive thing this device does, and the rest of the hardware doesn't match the Ion Elite on any dimension.
Slope
Both have slope. But the Ion Elite uses Bushnell's patented slope tech — the same algorithm behind their laser rangefinders — and it's the first Bushnell watch to include it. The Voice 3S+ has slope on/off but the spec data doesn't detail the implementation. Bushnell's slope reputation is strong from the rangefinder side; that probably carries over here, but I don't work at Bushnell.
Form Factor
The Ion Elite is a wrist watch (38g, IP67, 22mm standard band). The Voice 3S+ is a handheld that clips to your bag or belt — you can also detach the unit for cart mounting. IP67 vs IPX4 is a meaningful difference: the Ion Elite can be submerged briefly; the Voice 3S+ is splash-resistant only.
Battery tells an interesting story: the Voice 3S+ gets 18 GPS hours vs the Ion Elite's 12. If you're doing 36 holes in a day or playing slow rounds in extreme heat where GPS devices drain faster, that margin might matter.
Charging and App
The Ion Elite charges via custom magnetic 4-pin USB and syncs to the Bushnell Golf app for post-round stat review. The Voice 3S+ charges via micro USB — which in 2026 is genuinely inconvenient — and has no companion app. What you see on the device is what you get.
Who Should Buy Which
Get the Bushnell Ion Elite if:
- You want a proper GPS watch with course mapping, green view, and slope in one device
- You play unfamiliar courses and want to see the hole layout, not just three numbers
- You like reviewing your round stats after the fact
- You want IP67 waterproofing for wet rounds
- A 38g watch that disappears on your wrist is appealing
Get the GolfBuddy GB VOICE 3S+ if:
- You specifically want spoken yardages without looking at a screen
- You're an older golfer (or anyone) who finds glancing at a watch mid-swing awkward
- You want maximum battery life and aren't worried about course maps
- Budget is the primary driver and $129.99 is meaningful vs $219.99
- You play with people who'd find a GPS watch distracting in your backswing
The Bottom Line
The $90 price difference buys a lot: color display, green mapping, hole maps, touchscreen, shot planning, slope from a brand known for slope, and an app ecosystem. The Voice 3S+ isn't a bad device — 18-hour battery, talking yardages, 40k courses, no subscription — but it's a device built around one feature. If that feature (audio yardages) is genuinely your priority, it delivers. If you want a GPS device that shows you what you're working with on the course, the Ion Elite is the better answer at a reasonable price.
