Garmin Bounce 2 vs Garmin Forerunner 970: Which Should You Buy?

Overview

These two watches share a brand name and almost nothing else. The Bounce 2 is a kids' safety device built for parents of 6-to-8-year-olds who want GPS location tracking and LTE messaging. The Forerunner 970 is a serious multisport watch for adult athletes willing to pay around £600 for deep training metrics. Comparing them directly only makes sense if you are choosing one as a gift or trying to understand how Garmin spans its product range.

GPS and tracking accuracy

The Bounce 2 uses GNSS positioning for one purpose: telling parents where their child is. It is not tested for lap splits, pace accuracy, or track precision. That is appropriate for its use case.

The Forerunner 970 is designed for sport GPS accuracy, and its record here is mixed. In controlled track testing against competitors including the Apple Watch Ultra 3 and Amazfit Balance 2, the Forerunner 970 did not come out on top. At £600, losing a track accuracy test to lower-priced alternatives is a real weakness. Multi-band GNSS is present, but having the hardware has not guaranteed class-leading results in testing.

These two devices are not comparable on GPS accuracy. One is tracking a child's location across a school day; the other is trying to measure a 400m interval. Different tools, different standards.

Battery life

The Bounce 2 needs daily charging when LTE is running, which is the primary use case. Parents should expect to charge it every night. For a child's watch this is manageable, but it means a dead watch by pickup time if charging is skipped.

The Forerunner 970 offers extended GPS battery modes and firmware-level battery manager insights added in version 16.28. Exact hours from the available review data are not specified, but the watch is built for multi-hour training sessions and multi-day wear between charges, which is standard expectation at this price tier.

Advantage: Forerunner 970 by a wide margin for raw stamina, though the Bounce 2's daily charge cycle is consistent with LTE kids' watches across the category.

For athletes: who wins?

Running: Forerunner 970. The Bounce 2 has no pace, cadence, or training load features. The Forerunner 970 has weaknesses in track GPS accuracy but is built for this use case.
Trail and altitude: Forerunner 970. It has a barometric altimeter for pressure-based altitude calculation. The Bounce 2 has no altimeter at all.
Triathlon and multisport: Forerunner 970. Multi-sport profiles, SpO2, HRV analysis, and swim tracking are all present. The Bounce 2 is swim-proof but not a sport device.
Recovery tracking: Forerunner 970. HRV-based recovery tools require beat-to-beat interval data from wrist PPG, skin temperature, and SpO2. The Bounce 2 has none of these.

Verdict

Buy the Bounce 2 if you have a child aged 6 to 8 and you want GPS location sharing, LTE messaging, and basic activity tracking in a durable kids' form factor. Buy the Forerunner 970 if you are a serious runner or multisport athlete who wants Garmin's deepest training metrics and can accept that its GPS track accuracy does not fully match its £600 price tag. Do not buy the Forerunner 970 for a child, and do not buy the Bounce 2 for athletic training. These are two completely different products that happen to share a logo.
