Eggtimer Rocketry - Eggfinder

nice lightweight tracker designed for tracking small rockets, anyone used one? $100 for a tracker sounds attractive.

Is this similar to trackimo?

I have the Marco Polo because it uses IR rather than GPS. With so many variables affecting GPS sometimes, I wanted something a little less prone to outside interference. If I was going with a GPS tracker, I would look into the Eggtimer for sure. Thanks for sharing another option.
