Buying Guide
Display and Usability
A golf GPS watch must be easy to read in bright sunlight. The Garmin Approach S12 features a high-resolution sunlight-readable display, while the Bushnell iON Elite offers a bright 1.28-inch color touchscreen with a single-button interface. Both are designed for gloved hands, but the Bushnell’s color screen adds visual clarity for hazard layouts. For more on display technology, see our comparison of golf rangefinder watches.
Battery Life
Long battery life means fewer worries on the course. The Garmin Approach S12 delivers up to 30 hours in GPS mode, easily covering multiple rounds. The Bushnell iON Elite provides 12+ hours, enough for two full rounds, and recharges via USB-C. If you play frequently, battery endurance is a key factor.

Slope Adjustment and Tournament Legality
Slope-adjusted yardages give you “plays-like” distances for uphill and downhill shots. The Bushnell iON Elite includes a toggle to turn slope on or off, making it tournament-legal when disabled. The Garmin S12 does not offer slope, so it is always legal for competition. If you value slope data, the Bushnell is the clear choice.

On the other hand, the Bushnell Golf iON Elite GPS Watch, Black is ideal for those who want a vibrant color touchscreen, slope-adjusted yardages, and intuitive single-button operation.
