So, my son brings over his new camera equipped drone yesterday. The winds are around 30 mph with strong gusts. The quad just maintains it's GPS position without his hands on the controls. Even though it's being bumped a bit from side to side, the electronic gyro gimbal is keeping the camera image perfectly still. Quite impressive!

If they can cram all of that in a small package, then I feel they can do the same, with a Pro Chrono for less than a hundred bucks. I understand it doesn't take two readings, like a more expensive unit, but it appears that it's readings are quite comparable to the expensive units. One thing for sure, is that I use it in the desert, and it gives a what I'd consider to be a quite accurate reading, nearly every time.
