Metal detectors are a bit pricey but it depends on how serious you want to take it to be honest.
You can get a decent second hand one for about £350.00 then you need all the bits that go with it, Pinpointer, shovel etc etc...
1 year and 2 days until I finally reach the official Retirement age of 66.

Mind you I'm semi retired now and just do a bit of work 30...
