The benefit of All-Systems mode is dependent on how well alternative systems perform in your area. It is recommended that you use this mode for working out in the city near tall buildings, neighborhoods with significant tree canopies or mountainous terrain. You are still liable to deal with reflecting location signals even though this is a useful perk.

If one signal is blocked, you can still count on the other to pick up the slack, because dual-frequency mode offers the most accurate data you can get. It's for rock climbing sheer rock faces in narrow canyons, hiking deep within forests, in between mountain peaks, or near the Grand Canyon. It's nice to have, even if you don't need it outside of extreme conditions.

Most of our favorite fitness trackers rely on connectedGPS, which means you need your phone nearby to keep track of your workouts. If you're a person that likes to run without a phone on hand, you only need a fitness tracker with built-inGPS if you have a phone. You won't get dual-frequency data in the future.
