I was worried about my aging
P4P, even though it works very well. I added a Mavic 3 Pro, so that now I have a fleet of 2. My impression of the Mavic 3 Pro:
Plusses:
Longer Battery Life
Lighter, smaller to pack for travel
I think the camera is better
2 of the 3 lenses are nice. The tele - not that impressive
Easier to install filters, although the filters are pricey.
It shuts down immediately on landing. Easier to land in windy conditions, without mishaps. Low CG.
Black drone is pretty easy to see.
Minuses:
Set-up for take-off with all the unfolding, etc. takes longer
Riskier for hand catching, because the props are so close to the grab-point
Camera does not allow for video shooting and taking stills simultaneously. This is a feature I miss.
Not a cheap solution, of course. But the
P4P was pricey when I bought it 9 years ago, too. With inflation, I think the Mavic was cheaper. Although there are a lot more choices now.
