Ok here we go. On Friday "on shout" I said I was feeling lucky
I arrived at chosen field raining. Fly tippers had dumped a boot full of rubbish in gateway to field. I decided to kick a piece of wood out of the away, this was followed by a pulled muscle In my back up one side, something I have done in the past and had retired early as a paramedic with this injury many years ago...my next 1hr was spent not detecting but resting in car. Two times Co- Dydramol and an hour later, I decided to search,the rain had sopped and sun came out, the field was seeded and flat.
Over the next 4 hrs I persevered with short breaks when I finally called an end to the day. My final tally was 1 X Roman grot and a back as tight as a ducks Arse.
Over the weekend the back and neck settled down.
I await the next Friday 13th when I shall again return for vengeance although may be not put up a "shout" saying I feel lucky...lol..
PS off now for a few hours searching.
