We always flew with two trackers - one, a satellite tracker like the one below, and the second, an Android cell phone running our in-flight tracking code. We discuss all about the pros and cons of different trackers in our blog post here.
SPOT Trace GPS Tracker
This saved us several times when our balloon landed outside of cell phone service or when our tracking phone unexpectedly died. Requires a monthly or annual subscription.
How you choose to package your flight components is one of the parts you can be most creative with. We chose the simple, small, styrofoam cooler below, and cut out notches for our photography equipment. Styrofoam is ultra lightweight, keeps the electronics warm (sometimes too warm if it’s hot out), and gives a nice cushion upon impact when it lands.
Polar Tech 205c Cooler
We found the 6” x 5” x 6.5” size to be perfect for our many flights. It even gave us enough room to send up other items such as brewing hops and astronaut ice cream!
This list of items is not exhaustive. It is always good to be prepared and bring more than you think you’ll need to the launch! Items such as duct tape, string, scissors, and more.
36” Zip Ties
We use these to secure the payload cover and create attachment points to the parachute line
8” Zip Ties
Useful for securing other items inside the payload (camera, electronics) and creating loops to attach the parachute to the balloon
Used to protect the weather balloon during filling and handling from oils on your hands
