This is a mount I made and designed for holding a Garmin C1 pro chronograph along with a Kestrel 5000 series weather station. I designed this to be compatible with arca mount ball heads. Also, I've included a recess in the middle to allow you to press in a ¼ -20 insert so that you can also screw this on the original garmin tripod that is included with the C1. If you like this model and find it very useful, please consider boosting me. Thank you.
