Wouldn't colored smoke generators be more effective?

You could carry them on your person and have them available in the event you are on the move and hear or see aircraft coming near.

A 3/4" wide tape just does not seem very realistic unless the search aircraft is going to approach it at a perpindicular angle and thereby see that it is a man made device. Also the prospect of animals or weather pushing all or parts of it into the tree canopy do not seem to make it a secure type of signaling device.
