The Casio GBD-200 is the best low-emf fitness tracking watch and is great for those who are wanting to avoid constant Bluetooth or GPS connectivity and are interested in having a simple fitness tracker rather than a smart watch. The Casio GBD-200 allows you to track your workouts and offers the option to sync with your phone’s GPS for more accurate step counting, distance and pace tracking.

Key Low-EMF Features of the Casio GBD-200
Minimal Wireless Use: The Casio GBD-200 stands out as a low-EMF fitness tracking watch because it avoids the heavy reliance on continuous wireless technologies and is built with a focus on simplicity and functionality. It primarily uses minimal radio signals for syncing time and workout data, which reduces its overall EMF output. While it’s not entirely free from electromagnetic fields (as most electronic devices aren’t), its design significantly reduces EMF exposure compared to most smartwatches and fitness trackers.
Connection-free fitness tracking: The Casio GBD-200 has a simple design which is focused on basic fitness tracking (steps, calories burned, etc.) and is optimized for sporadic GPS use, mainly when needed for specific workout tracking or route mapping. It doesn’t continuously track heart rate or require real-time GPS syncing.
According to Casio, “Step counting is accomplished with an accelerometer and Casio’s proprietary algorithm delivers highly accurate distance and pace measurements. Distance adjustment is also possible pairing with a smartphone’s GPS. After adjustments are made, the watch can measure walking and running distance more accurately, even without needing to be connected to your phone”.
Airplane mode: When not syncing workout data or using GPS mode for GPS tracked runs, you are able to put the watch into Airplane mode to stop wireless communication and prolong your battery life. This is a fantastic and unique feature compared with other smart watches and fitness trackers giving you full control over the syncing of your data and unecessary battery drain.
Bluetooth optional: The GBD-200 only uses Bluetooth to sync data (e.g., activity, step counts, etc.) with the Casio Watches app if and when you choose to, or if you decide to use GPS pairing. You also have full functionality if you are mainly interested in just using the watch itself without needing the Casio Watches app.
