The Polar Pacer features an always-on MIP color display. This screen type offers clear visibility in bright sunlight and remains readable without needing to lift your wrist or activate a sensor. The Polar Unite does not list a specific display technology in its provided data. While the Unite focuses on essential health tracking, the Pacer’s display ensures you can check your time, pace, and distance at a glance without interruption.
