Test Drove a GPS system
My previous employer purchased this same setup. They did a Boundary survey on a 10 acre wooded parcel with both the GPS and robot on state planes. Each survey was within a tenth at all corners. Pretty cool if you can trust it. The tsc7 is too large for the woods in my opinion but would be great for construction staking. Also, it is too much like a computer. I don't want to be reminded of virus protection updates in the middle of surveying. Tsc3 is the better option to me
The other advantages like receiving files via email directly on the tablet, emailing the download back to the office etc, or even just easier file transfer via flash drive make me not like the older stuff like the TSC3 and its lack of functions.
I liked the size of the TSC3, but the TSC7 is worth lugging around if you're doing anything other than rough woods work. With SIM cards installed on them, we push data directly to and from the controllers, no email necessary.
I anxiously await the day when we can drop the physical screen altogether and get a holographic screen that appears above a small rugged keypad...
Set nails at a few points in the boogers that would represent normal field conditions for jobs you encounter and then come back to those points several times at different times and compare the repeated observations to really prove that when the receiver says it is fixed it is really fixed.
The only problem I see in that procedure is that he needs to do everything 2x. Waste of time and effort. For control points, I would agree with you. But for topo ground points that is a waste of time. A longer logging time under canopy would be a better approach but still, it won't guarantee no false fixes. It is what it is I guess.
The spectra precision receiver is low priced but from what I’ve heard is not that durable. It might be ok as a base station.

I have worked for two firms that used them, and they definitely were of lower build quality. The shell was pretty flimsy, and there were frequent problems with both the battery compartment lid and the front face buttons not holding up to repeated use. That being said, they worked about as well as I would expect them too.
It was a relief to make the move to a firm that invested in the good stuff. There's a night and day difference, in both build quality and performance, between the Spectra stuff and the Trimble stuff.
