Caves, Deserts and Water DexNav

[JackMat98]

Can I get some tips for DexNaving in Caves, Deserts and on Water? I have heard it is harder, but I wanted to know a way it can be made a bit easier. I'm currently trying to get a Shiny Gible on Route 111 after getting Shiny Whismur and Shiny Corphish today.
