There is so much to learn about metal detecting but to keep it short.
If you can have him try some different brands out as some are better balanced than others, swinging an unbalanced machine can wear your arm out pretty quick.
I would skip the starter machines as they are very limited, start at the intermediate range with ground balance, DD coil, fast recovery.
I would also suggest getting him a hand held pinpointer they run around $80-$100+ for a good one like garrett, Teknetics, Makro, Whites, Minelab.
Also a set of headphones they run about $30-$100+ and a good shovel or digging tool.
There's also waterproof machines available if he would do any water detecting.
Stick with a name brand machine like Garrett, Teknetics, Fisher, Tesoro, Makro, Minelab, Whites.
There are even fake chinese knockoff products out there like the garrett carrot pin pointer and Teknetics T2 to look out for as well.
Some deals going on like the Teknetics T2+ bundle with pinpointer is a great deal for $549 free shipping with a 7 year warranty.
Also the new Minelab 800 & 600 are the newest hot machines out now.
If you have any questions just ask.
