Buyer's Guide: Selecting GPS Training Gear

  1. Multi-Band GNSS: Dual-frequency satellite tracking locked across GPS, GLONASS, and Galileo prevents signal drift in canyon trails and city skylines.
  2. Display Tech (AMOLED vs. MIP Solar): Bright AMOLED displays offer vivid color inside, while Memory-in-Pixel (MIP) solar panels excel in direct sunlight.
  3. Sensor Ecosystem: Ensure devices support both ANT+ and Bluetooth Smart protocols to sync power meters, heart rate straps, and smart trainers.
