AdirPro 360 Prism Topcon Sokkia Style
Does anyone have any information about the quality of the AdirPro brands, specifically their Topcon ATP1 style 360 prism (AdirPro MFG No. is 720-15)? I have the older Topcon A6 prism but would like to upgrade and this prism is about half as much (or more than half) as the Topcon brand prism.
Here is a current link as of this post but the manufacturer number is 720-15
I hope to tighten my surveys up a bit with the newer style prism as I hope it reduces the offset errors when not having the A6 perpendicular to the scope.
I see a lot of really cheap $150 +/- options on ebay as well, but those have to be junk, correct?
Thanks for any insight.
