I could not help noticing your new entry for Leica Geosystem items.

an impressive set of kit to be partnering with.
a NN used with an optically centred tribrach should even give the possibility for time lapse progress work.
Though I do not think many normal photographers would have the spare cash for a full leica surveying kit.
whilst surveyors would have no trouble buying the NN kit.

I have been wondering what set you off on this more unusual tack.?
