Surely you're correct !!
I might ask "what's more costly, levelers or a fridge gimbal?". Its easy to imagine that there are a number of answers ... personal preference, rig size, and etc. :-)
Thanks for your answer ... something I might consider, given that such a system is possible.
Stupid, question, but how can you tell that you are 6 or 3 or 7 or 10 degrees off level ?
There are sinple inclination tools out there you can buy.
I used math to calculate 1 degree elavation change; I calculated 4" elevation change for a 20' run. So 3 degree is 12" of elvation change over 20'. 6 degrees is 2' of change.
