I've seen the P4p
And it also cruises faster than the Mavic Pro to go along with that longer-lasting battery.
I think you mean flying with the signal going through trees, where you don't have direct LOS connection. In that scenario I think Ocu-sync has better penetration through trees. I use my Mavic in those conditions where penetration through plants is needed. But with clear LOS connection with P4P on 5.8Ghz, the P4P excels with range and it can go farther due to more battery endurance.
