Because I recently started making videos this summer on youtube. But I couln't resolve myself to make some about water metal detecting and especially not when i found nice gold ! ( okay maybe just once but it was in french and metal detecting was only a small art of the video so I was sure I wasn't creating myself new competitors). That's my problem, I enjoy MD mutch more than making videos and If I did, I know I would see tons of guys hitting my favorite spots afterwards.
There is one guy making a lot of videos, strangely finding a lot of gold in a heavyly hunted area in Quebec now. But this guy is also a Metal detector dealer and i'm pretty sure he sell a bunch of those and It must be really tempting to plant a few finds, It's so easy to do.
