Coros Apex 4 Leaked Specs Include Dual Range Barometer

The Coros Apex 4 is leaking details ahead of any official announcement, and the headline spec is a dual range barometer. That kind of sensor setup targets more accurate elevation data across wider altitude ranges, something trail runners and mountain cyclists will care about directly.
A dual range barometer addresses one of the persistent weak points in GPS watches. Single-sensor barometers on watches like the Garmin Fenix 8 and Polar Vantage V3 can drift or struggle at extreme altitudes. Coros appears to be stacking two sensors to cross-reference readings, which could tighten elevation accuracy on long alpine efforts where 50-meter errors compound into real navigation problems.
Coros already punches above its price point on battery life and GPS accuracy with the current Apex 2 Pro. The Apex 4 building on that base with upgraded sensing hardware puts pressure on Garmin's mid-range lineup. If the barometer improvement translates to cleaner ascent and descent data in training load calculations, that matters for structured vertical gain workouts.
Details are still composite leaks from community sources, so treat exact specs as unconfirmed. More hardware details are expected before release.
Early signs are promising. If Coros delivers clean barometer data at Apex 2 Pro pricing, it becomes a serious option for trail and ultra athletes who rely on elevation metrics daily.
