    Found another box of old rocket stuff from my first stint with LPR. Never did it as a kid. Bought this back in 2003-4 timeframe. I'm pretty sure it needs an A23.

    Hey, I never knew they made those, looks like a nice little package.

    What's the big grey thing?

    It's a directional microphone, came with a set of headphones. Sweep the area and listen for the loudest direction, then start walking/hunting. I'm glad I didn't leave the battery in it to leak and corrode everything.

    That’s pretty neat. the directional mic might be a little over the top though

    I dunno, could be useful. I think @BABAR recently proposed using a cheapie parabolic mic with a screamer to help in tracking... looks like Estes already went there, in some version.

    No, Transroc-II absolutely was NOT a radio transmitter, it was an audio (sound waves) beeper, and the handheld thing was a directional sound wave amplifier. It was a travesty that they called it by that name.

    The real original Transroc (1971) was a radio transmitter, that could use various sensors, or even a microphone, and could be used as a tracking beacon too. It used a 27 mHz walkie-talkie. I might have gotten one, except I got a "Foxmitter-3" kit (Foxmitter-3 sort of inspired the Transroc),and it was my first ever PC board project.

    Info on the real Transroc:

    The original Transroc transmitted on CB channels 11 or 14.
    I got one when I was a kid. I little more complicated to build then those Radio Shack project in a box.
    Never got mine to work. :(

    The Transroc II is a sonic device.
    Bought one and tried it out. The sonic beacon worked fine, never could quite get the directional microphone to guide me to the rocket. :rolleyes:

    My 15y memory remembers the same thing. Just loud(?) beeper and the microphone thing didn't help much. But putting a new microphone in it and a removable parabolic dish sounds like an interesting project.

    Found it on my old range box. It needs a 6v battery Battery 2CR1/3N.
