We also use a Nikon tetrad scope. We purchased from Carl Singer a
needle holder that mounts on the existing mechanical linkage,
and several boxes of precut needles. I accidentally broke the
first needle I mounted, which I did not realize for a bit, because
even broken, *it still worked better* than hand-cut.
Also, the needles last a good long time. Definitely
worth the investment for us! In fact one of the students
now claims doing tetrads is like playing a video game....
I have no official connection with Singer Instruments, just
a satisfied user.
