I have a 3/4" Conduit that seems to be blocked at the end. We can kind of
hear the Fish tape tink at then stopping point, though we don't know where
it is... We don't know how to locate the end of the conduit. We were
thinking if we could see the end, it might help us determine the location.
It is about 6'-8' to the end of the conduit. I've tried looking for Small
Cameras, but nothing that will really fit in the Conduit. Found a bunch of
Borescopes, though they are too expensive.
It would be great to get something like this:

short.
Any Suggestions on how to see to the end or find the end?
Thanks!

Uhh... pull the tape out and measure it?
What's in the conduit now, and where does the conduit go?

The conduit is from a Pull Box to a Driveway pillar. Nothing in it now. We
want to Light the Driveway Lights, though cant seem to figure out how to get
there from here, The Fish tape does not come out anywhere to connect up to
the lights.

Yes but if you're using a wire fish tape, then you shove it in one end
until it hits something, then you pull it out and measure how much
tape went into the conduit. That tells you how far away the blockage
is, and with any luck, you'll be able to figure out roughly where.
(this assumes no bends that you don't know about.)
Then you'll know where to dig, or what to take apart to clear it.
Have you tried running the tape from the first pillar? That
would give you another data-point.

Trick we have used on water pipes:
Take a carry tank and connect hose to conduit.
Blow 100 psi air thru and search for the "whistle"
at the other end.
Alternate: pump Mercaptan in with the compressed air and
locate by smell.
