Photoelectric activated locator
Does anyone remember who sells the sonic beacon that starts beeping on ejection being activated by a photoelectric eye?

Pratt Hobbies MicroBeacon
Snap in the battery, and put a wrap of tape around it to secure it. Loop the KevlarŪ lanyard through your nose cone eye screw, or tie it to your shock cord, and tuck the MicroBeacon into your rocket on top of the chute. You're ready! The MicroBeacon is not loud; if it were, it would have to be bigger and heavier. However, because of the warbling tone it generates, it's easy to hear under most conditions. Ever notice how far away you can hear a cell phone ring? Same principle! Price: $12.00

I've got a couple of these units and they are nice. They start screaming as soon as you plug in the battery. But you can put a thin strip of plastic in between the spring and the battery. Tape the plastic a few inches up the recovery harness. This keeps the darn thing quiet until after deployment.
