Anyone got one they want to sell for less than the $650 cost of a new one?
Or know of a decent alternative that costs less?
There is a no name copy on ebay for $150, but I wonder how good it is.
I know quality surveying equipment costs, but even by that yard stick, the GRZ101 is pricey for something the size of a boiled sweet!
If you are running a Leica 1200 you might want to check to see if you really want one.
I thought I just read somewhere that the Leica 1200's are having trouble finding these prisms with Power Search.
Seco Mini 17.5mm Nodal works great for close in stake out.
Yeah, thanks - I did read the thread about that issue. I sometimes use a 1200, but mostly a Sokkia SRX - and I use a 17.5 leica mini with it. The RC unit on the Sokkia is a pain for other reasons but I have no doubt it will find a GRZ101.
I guess it depends on what consists of "good enough" to you. With the Leica you get a bit more comfort level. We used to have six SECO mid qualities and two Leicas. The Leicas seemed to perform a little better, especially in terms of autolock collimation consistency, but the SECOs were probably good enough for 99 percent of projects.
In my experuence if you get a project requiring that level of precision, the possible profit margin should pay for a couple of top-of-the-line minis.
I should also say, though, that we had a couple of the cheaper minis, they definitely were not as consistent...I rhink they were CSTs
Also, keeping your scope and prisms clean mattered way more than any of the above.
Just to clarify - the GRZ101 is a mini 360 prism. I was not aware that Seco made something similar, though I could be wrong.
Gotcha, never used one of their mini 360s but they look nice. The full-sized Leica 360 is rather superior to the Trimble IMO.

It's also a heavy beast. I only use mine for wide-open dirt topo where I'll be ranging more than a few hundred feet from the gun. I mostly use a Leica mini (not 360) and just live with the pointing hassle.
I have the mini Grz101 which I never use but if a nice industrial bolt job comes along for sure I will use the GRZ101 for it has the best 360 centering possibly due to its small size.
I had the full size prism the GRZ122 and returned it For
a Leica MPR122 360 a little smaller/lighter and a hell of a lot tougher than the Grz122 5/8 thread top and bottom
The MPR 122 follow seems better and over all a better looking unit and about half way in size +-+- between the GRZ101 and GRZ122. The centering as not dependent on pointing arrows on top like the GRZ122
