Has Minelab made any changes on 2020 Nox 800 units compared to 2018 units? I see there are complaints about ears on coils that could be stronger and water leaking into unit. I hope to be getting mine soon. I have used a DFX since 2002. I found a lot of stuff with it but it pales in comparison with the Nox 800
