62 mm prism with 5/8 on top
We use 25 mm mini prisms for almost everything, and the seco model we use has a 5/8 thread on top so that we can put a GPS receiver or antenna on top of the prism. The prism itself tilts but the prism holder does not.
However, sometimes we need a larger prism for longer distances. I had a very old topcon prism (non tilting) with the 5/8 on top, but I dropped it recently and it broke. We have several 62 mm prisms that tilt but do not have the 5/8 thread on top.
I looked on Seco but could not find a 62 mm prism with 5/8 thread on top. Anyone know of another source? Offset does not matter, I will determine that on a CBL and enter it as needed.
