The BeepX works best on those larger diameter rockets where you have lots of room inside. It is a big unit, about the size of an Estes D12 rocket engine, although it only weighs 36.8 grams with its battery. It easily mounts to a payload bay tray with the supplied circuit board posts and screws. You can put it next to your altimeter or flight computer. Just aim the piezo so that it points out a hole in the side of your rocket so the sound is at its maximum.
Using it is simple. As you're prepping the rocket for flight, press the pushbutton to turn it on. It will beep 10 times to tell you that it is active. Then it beeps once per minute for 25 minutes. It is kinda in a sleep mode at this point to save its battery. During this time, you've finished the prep work and then you've launched the rocket. If you find your rocket sometime during that 25 minute pause mode, that's cool, you just turn it off. But if you don't, then the unit will come on like an annoying alarm clock and beep loudly once every 5 seconds. Its loud piezo sound will draw your attention and lead you to your lost rocket like a pied piper. Once it is activated, it can go on chirping for a full 11 hours. But I doubt it will take you that long to find your rocket once this thing is chirping away. You'll have people telling you "turn that thing off, its hurting my ears!"
This unit also works well in RC airplanes and sailplanes too! Think of the fun you could have with it at a party.
