The full review

GPS Accuracy

Whistle GO Explore uses GPS + LTE triangulation with updates every 15 seconds in real-time tracking mode. Location accuracy is 5-20 feet in open areas, 20-50 feet in dense urban environments. For finding an escaped dog, this precision is sufficient for block-level accuracy.

vs. Fi Smart Collar

Fi Smart Collar provides GPS tracking in a collar form factor (no attachment weight). Whistle attaches to existing collar. Fi's battery lasts 3 months vs. Whistle's 7-10 days. Whistle adds health monitoring features Fi doesn't provide. Choose Fi for tracking-only simplicity; choose Whistle for combined health + tracking.

✓ Buy it if…

Dogs who escape regularly, dogs who hike off-leash, or owners who want GPS peace of mind plus health monitoring.
