hey i am 16 and from the uk i love the ben heck show and it would mean so much and inspire me if my suggestion was considered...
i have a old radio shack metal detector and it would be cool if ben got a cheap metal detector and made a mini computer on it and increased the magnetic field to whatever depth is required and if there where any cool finds then you could catalog it into the computer and after a day of detecting you can go home and connect the detector to your laptop or pc and see how much power you used how long the detector was used for that say and see what was cataloged and also the detector had a little camera so when you catalog the item you can have a picture of what it was i think it would be a great idea and there are alot of metal detector enthusiasts out there that would love this build and to see ben do it would make me want to give it ago aswell i hope you consider my idea
