I'm also a senior, and I like technology and I like RealSense. With Smart Mode turned on with RealSense on, one can easily do Watch Me or Follow Me. With Watch Me, the camera always points at the object holding the ST16. With Follow Me, you can independently control the camera which would enable one to capture interesting video of anything in the area in proximity to the H Pro. So, much like flying in CCC, its having the H Pro in Auto Pilot mode while the pilot operates the camera and does not having to worry about the H Pro crashing into anything.
Amen, Bro, and I'm older than some rocks. Here's the deal for our questioner ( who I told I could not answer for him): On a money vs capability basis, no it's probably not worth the extra expense. If you enjoy what you have, maybe like to make videos, no it's not worth that grand. BUT, if you like to be on the cutting edge of this tech, if you like excitement and fun, if you like to push the boundaries, go for it, this is the best bang for your buck. The Pro is awesome, unreal, spooky at times, and more fun than that barrel of monkeys you once had. I say this as the owner of a 435HP Mustang.
Your dough, your choice. Good luck!
