Their commercial vid would sure have you believe it's ruggedized, and it's build seems to back that up to some extent. I will likely get one to keep my F3, F5, F5+ Sapphire company.
Wikipedia describes the 810G standard as one with many test categories and parameters, but which the MANUFACTURER can decide, which, IF ANY tests they use to call their product rugged according to its application. If they claim 810G standard they are to specify the parameters AND the tests used. I'm off to the Garmin site to see if they provide these details........
