Dutch Hill DH-1000 Tripod for Robotics?
Anyone using these with robotic total stations, specifically, a GEOMAX Zoom 90? I use SECO TRI-MAX typically and need to add another tripod to the truck , but wanted something lighter for use with a level, as well.
Input is appreciated.
I wouldn't buy composite legs for a robot. I had a set of Dutch hills and my trimble s6 lost its mind on them, the instrument would just shake.

I haven't used Dutch Hills lately, but I did have a couple different DHs with the composite heads and round leg components back in the '90s. They would literally make a moaning sound, like a tuning fork, in a moderate wind. This was before instruments with internal compensators, which I'm sure wouldn't have liked that. Then one day the head broke suddenly and the instrument hit the pavement. There was some mishandling going on there so I don't blame that all on the tripod, but it played a part.
I'd probably be willing to go with these DH-1000 tripods for levelling, but I can't see any compelling reason to put my robot on one. For one thing, that composite head would easily get scratched and then you would never get the instrument to stay level.
Composite tripods such as the Trimax are nearly as thermally expansive as aluminum. Durable and reliable, but not the very highest precision.
I prefer the Leica GST120-9 tripods. Reasonably light, very stable, high quality, not super expensive. The wood has very low thermal expansion.

I definitely didn't know that. We've used those at places I've worked in the past, believing them to be the most sturdy, and assumed to be the best.
Good to know. Thanks
