does any body know much about them??
I'm looking to design a cheap system for tracking items that are lost at sea.
a range of 200m should suffice.
basic cost should be no mroe than 10 units fo your local currency
the detector can be failry basi, either leds or sound or LCD. looking at less than 100.
I've only started looking itnto the trasnducers so any advice would be greatful.
so far i have looked at the ones used for avalanche revoveries and wildlife tracking as i reckon these would be cheap and suit my needs.
