Another simple way - the old Native American waiting for a train
method. Push the fish tape all the way until it stops. Person 1 keeps
ramming the fish tape and person 2 puts ear to ground near far end and
listens for it. Needs no batteries or smoke.

Nix the water. I like the compressed air trick, Just don't look
directly at the conduit end . .

Well, how about combining the two methods? Find some flex lawn drip
irrigation tubing. Attach a bosons whistle to the end and shove it
through the pipe. Add compressed air and it should scream like a
banshee. That should be easy to hear through the sand. Maybe the
duct tape will act as a diaphragm.
