What is my equipment worth?
This is the sort of thing you are looking for:
If you tell us what you are up to, we could help you go there. Are you looking to get these going, and use them? (Personal use) or get them going, and sell them? Like others have said, they are "useful antiques" in my words.
There was a day when we'd have paid thousands of dollars for them! I'm sure that there's a data collector out there, that might work with those. I've never used either of those, but are either of them fully electronic? If so, that's the one to fix up. Electronic means it'll send data into a handheld computer.
Anyhow, surveying is not a "get rich gig". But, it has its addicts. Kind of like people who love cars, or farming.
I have a Zeiss Elta s20 Robot. It uses a HP48gx data collector with SMI. I tried to sell it a year or two ago for $2,500 and could not find any buyers and that was with batteries and data collector.
It does appear as though yours is a robot as well. The handle having that little black piece on it is an indicator of that. That is an IR sensor that looks for a "dog whistle" on top of the prism in case it looses lock.
The guppy will still operate as a mechanical theodolite, even If edm is nfg.
The zeiss would be interesting to have for nostalgic purposes. Ive never seen one in use
Maybe I shouldn't admit this but I still have a Zeiss Elta S20 robot in service. I'm running survey pro robotics on a Husky FS3 and on board.
Don't let its age fool you. It's a bulletproof instrument and data collector with high build quality. Aside from close range tracking, I prefer it to our Trimble robots. It's certainly in the shop a lot less.
That being said, my instrument has value to me, but it's barely worth the shipping to anyone else.
Any more pieces and what software? Without the radio, data collector and quicklock, it's only a 2 man gun. If it has survey pro on board, then it's still one of the fastest 2 man setups for topo I've ever used.
Maybe I shouldn't admit this but I still have a Zeiss Elta S20 robot in service.
When I first entertained the idea of going robotic I looked pretty hard at the S20. It seemed like a very capable instrument, but before I even got close to pulling the trigger it seemed like Zeiss stopped promoting it, and I didn't want to buy an orphan, so I held back.
