Ipx566 - Better

Salt spray corrodes. IPX7 assumes you submerge the device. IPX6 assumes a deck hose. But on a boat, you get both: crashing waves (high pressure, short duration) plus constant salt spray mist (low pressure, long duration). Only a device certified IPX566 handles the wave impact and the subsequent drying corrosion cycle.

E-bike displays are mounted on handlebars. They face road spray (IPX5), power washing from owners (IPX6), and vibration. IPX4 displays fail in week one. IPX7 displays fail when the bike is parked in the sun and then rained on. IPX566 is better for the daily commuter who rides through construction sites (muddy jets) and light rain. ipx566 better
