This is the one I like best for my
Air 2.
Using for the outdoor flight with special terrain, it can prevent external interference when gimbal self-checking or landing | It can also prevent the propeller from blowing dust and dirty the aircraft when taking off and landing | The landing pad pro is made of PU double-sided two-color design...

It's small enough to fit inside many cases. Its rigid so supports the drone on grass.
AND finally, the precision landing is based on the bottom optical sensors matching the landing location visually after GPS gets you within about a meter or so. My Air two always lens with 3-4 of the rotors over the pad.
I have a big round one that is fabric over memory wire. Its OK but recently I have been using this.
Other places sell this one too that might ship faster.
