A good tripod will bring out the best in your spotter.
I bought one of these a while back
Zeiss Manfrotto Carbon Tripod with Fluid Head On Sale!
It's awesome for what it is, a full size tripod.
I also have a cheap $30 tripod I use for my chrono.
Yesterday my Zeiss Diascope 85 T FL with the new Vario 20-75x eyepiece showed up, right as the sun was setting.
I scurried to get it setup on the Zeiss/Manfrotto tripod, and setup the (for sale here on the Hide) Vortex Razor HD 20-60x85 next to it on the other tripod.
The Zeiss was a little brighter in the waning light of dusk but the resolution was far better. I was spotting a small sign in a parking lot a few hundred yards away, and the lettering was sharp as a razor through the Zeiss but the image had that I-can't-quite-focus look that comes from lower resolution through the Razor.
Before I put the whole works away I mounted the Razor on the Zeiss tripod and guess what? The image through the Razor was just as sharp as through the Zeiss.
I could not otherwise detect any sway or vibration mounted on the cheap tripod, but it was there.
The fluid heads are the $hit, too. Having used one, I can't go back.
