Total Station for ~$1K
IMHO, a data collector is a must, even just to get the angles and distances etc into electronic format. Hand-writing them sucks.
This one is still available. 😉
Make an offer, we hate to just throw it away.......
The instrument Hi-staker is offering will work with your Trimble TSC1/Survey Controller if you follow the instructions in this document that I prepared almost 19 years ago.
An update: I guess I spent too long staring at an eBay listing for a Nikon DTM-850, because the eBay algorithm autogenerated an offer for $100 off of the $700 asking price. I countered for another $100 off, and the seller accepted, so I ended up with a DTM-850 for $500. Even better, like me, it's in Canada, so that's $500 Canadian ($400 USD). And for the cherry on top, the seller is in a city only 4 hours to the west of me, and apparently a cracker jack when it comes to shipping, because I had the total station in hand by 5PM today.
The battery that it came with it won't hold a charge, so I opened it up, cut out the cells, and hooked the wires to a small DC-DC converter I have connected to a Milwaukee M18 battery adapter set for 7.4 volts out. It's hideous, but until I can re-cell the battery or get the right Hirose connector to power the thing from the data/power connector, it lets me test it out. The internal lithium battery backup is also dead, so I'll need to figure out how to replace that too.
Fiddling around with it in my house with a peanut prism, everything seems to work as expected. It comes with a fairly elaborate on-board software suite, including full data collection capabilities. I'd still like to hook it up to the TSC1, so @glenn-borkenhagen your documentation might still be helpful if similar instructions apply to the DTM-850.
