As the title says really. Anyone got any tried and tested methods of testing for sound connections between caves when you've insufficient people to have somebody each side? I'm thinking along the lines of...
1. Enter cave 1, leave device making noise and exit cave.
2. Enter cave 2 and see if you can hear it.
The 'device' will need to be loud (i.e. equivalent of someone shouting) and be able to make said noise for a couple of hours to give time to get between the locations. It will need to be cave proof (but not waterproof) and not matter if I leave it for a week or two should I not bother to go back into cave 1 on the same day to retrieve it. A bonus would be if the device also emitted light, though obviously leaving a torch shining is the obvious solution to this. Ideally something dirt cheap.
All ideas welcome though I'm particularly interested to hear from anyone who's had success doing this sort of thing.
Cheers in advance.
