Estes E2 tracker...what is it exactly?

Post by LFO » Wed, 03 May 2000 04:00:00



My local hobby shop has the Estes E2 Tracker for 30.99.  It looks like a
large hand gun with an LED and compass mounted on top.  It comes with a set
of head phones and a "transmitter" that fits in most body tubes.

I was not able to open and inspect the transmitter, but it looked like a
simple sonic beacon (i.e. it makes noise).  If that is the case, the
handheld device is nothing more than a audio amplifier with some sound level
intensity driver circuitry for the LED.

Is this transmitter RF or sonic?  The box states a detection range of 200
meters.  This type of range specification is typically used with RF
transmitters (in that your "hearing" is not a factor in the range).

Anyone?

Buy it if you can get for $5.99.  Throw away the microphone pick up and keep
the buzzer.  The headphones might be good if you need a cheap set.  That is
about all that's worth on that product.

It's sonic.  The "transmitter" is nothing more than a high freq piezo buzzer.
The "tracker" is just an audio amplified of very crude design.  That LED is just
a power indicator.  The compass is worthless, kind of like the compass in the
stock of a Red Ryder BB gun- it's more for looks than navigation.  I've played
with the tracker a bit and it has very little directional capability and the
sound amplification is very poor quality with a lot of noise.

In my opinion, absolutely NOT worth the money.

It's a cheap sonic locator.  A noise-maker goes in your rocket,
and the E2 has a microphone pickup to help you find it.

Rocketry Online has a cool how-to article that shows how
to convert a Radio Shack "personal alarm" device into a
screamer that starts up when the nose cone pops off.  Cheaper
and easier to use than the E2.
