In my view two of the main reasons are -
1. The risk of meeting strangers in isolated places, especially for ladies.
2. Issues regarding permissions.
I did suggest going to rallies, where they might meet people and that result in buddying up in time but I know a lot of poeple are not fans of these.
I also said anybody near the coast, as in Macroman's case, and wanting a buddy it might be worth saying specifically "A buddy for beach detecting" as that would remove any potential issues with permissions.
So after that waffle, (as said a bit back I am a member of the "Long Ass Posters Club"), here is a thought. While we still have "light summers evenings" (currently near dark outside and looks like chucking it down hence quotes!), what do people think about the idea of meeting up for very informal midweek evening beach sessions?.
As on "town" beaches this would remove both the risk of meeting strangers in isolated places, and there would be no issues regarding permissions.
What I am thinking is a couple of days before a person puts up "I will be detecting XXXXXX beach on Wednesday evening, starting from XXXXXXX car park at 6:00 if anybody fancies joining me".
Being where I am, 2 hour drive to my "local" beach, I rarely do beaches but could be up for the odd one like this. However I would like to know what those that are near the coast and beach detect think. Puts on tin hat ready for response
