How do the Garmin Edge 540 and Wahoo Elemnt Bolt V2 compare in heavy rain?

The Wahoo Elemnt Bolt V2 relies entirely on tactile physical buttons, making it immune to water droplet interference. The Garmin Edge 540 uses physical buttons supplemented by partial touchscreen input, which can occasionally misinterpret heavy rain as touch commands unless locked.

Which device offers faster rerouting when making a wrong turn?

Both devices offer fast rerouting, but the Garmin Edge 540 calculates complex detours directly on the device utilizing its onboard map rendering engine, whereas the Wahoo Elemnt Bolt V2 handles route adjustments quickly with minimal delay.

What is the significant difference in battery endurance during long rides?

The Garmin Edge 540 provides up to 26 hours of standard battery life (and offers a solar option), significantly outlasting the Wahoo Elemnt Bolt V2, which delivers approximately 15 hours of battery endurance.
