Watch this post as I may edit in, more info.
My experience has been prone, sitting, kneeling, standing & bench.
Pictured is my ancient Ewing stand I used and later added the Ray-Vin head. The head is great.
When ray-Vin came out with their stand, I immediately saw the advantage of the legs swiveling to the "pointing up" position.
This makes it a smaller manageable package. The "clamp onto your stool" options is a great feature.
Pricy as these items are, I stuck with what I had. The Ewing stand does allow you to lower your scope so close to the ground a passing cricket could spot for you. That white Delrin washer was added to keep the scope outta the dew. (and crickets)
I'm guessing an extra section of post would be handy for standing position & bench work. At the bench I use the stand on the ground for the 88 mm scope.
Ewing stand with Ray-Vin Head. No scope attached. ...................Hic-tec base. Nice tool to set your tightness.
Really low to the ground. Legs fold downward.
Places scope too close to shooter in prone.
The legs are 12" long. Like the Hic-Tec better.
Hic-Tec pretty short 1st section....................Total Eclipse Option has adjustable prone set up.
Might want another section ......................... Keeps stands legs out of your operating area.
