Here’s a photo report: a homemade armrest for Minelab Go-Find metal detector. Interestingly, such an armrest can be removed, doesn’t require any changes to its original design and is cheap.
It could be said that this one will fit other machines as well. But having a pretty good original armrest, other detectors can do without it. So it’s for Minelab Go-Find only.
All info on metal detector armrest is collected here – original and homemade ones, how they break down and how to repair them.
