Add GPS to some of your smallest rockets with no av bay needed.
I have not found a smaller standalone tracker case anywhere.
Just use a piece of Kevlar cord and tie it to your rocket's shock cord and instant GPS tracker with your Eggtimer Mini Tracker. The 1S cases are only 1"x1-1/2", and 3" tall.
For the 1S Eggfinder mini, you will need to replace the standard connector with a 1S, JST-PH connector and use a PL 402035 battery readily available on Amazon. Link Below
This 2S Eggfinder mini case is only 1-3/8""x1-1/2", and 3" tall. If your tracker is set up on a standard JST-RCY plug, then no further mods are necessary—link to the 2S battery below.
The Featherweight case is designed to be used with the 400mAh battery provided by Featherweight.
Made with high-quality brass heat-set inserts for the lid by Ruthex, yes, there is a difference.
***THERE IS NO STANDARDIZED POLARITY SET UP ON JST-PH PLUGS. YOU HAVE A 50/50 SHOT OF GETTING THE CORRECT POLAIRTY ON AFTERMARKET PLUGS AND BATTERIES. ALWAYS CHECK YOUR POLARITY AND SWAP THE LEADS IF NECESSARY***
See video here on how to swap leads to ensure correct polarity.
2S Battery pictured can be ordered here.
Tracker and Battery NOT included.

Great quality product and excellent service!
Using the “Tracker Case” makes for a safe way to hold the actual tracker BUT most importantly it is SO easy to move from one rocket to another!!!
works like a champ. Great price and shipping time!!!!!!!
