It's pretty much normal for any sport or hobby, to brag, boast, and embellish. When done around family, friends, teammates, it's usually taken humorously, no big deal, just having fun. Unfortunately, most of us have never met, and we only know each other from what is posted here.
For me, I hunt for the adventure, relaxation. Would be cool to dig some silver and gold, but hasn't happened yet. Been told it sink pretty deep, in this sand, we refer to as 'dirt' here in Florida. But, it's a lot of free time, lot of thought and imagination. Some people not separate their thought so well. It's also more important to so, more than others to fit right in, be an integral part of the club. And for those out there, dripping in sweat, and hardly finding much of interest, it's tough. There are always doubts about whether the machine is working right, settings appropriate for the location. Would a more expensive machine find the silver, or do I just need to learn more about the current machine?
Location plays an important part, you can only find, what's in the ground. Not ever place you hunt, is going to produce.
Think it's best, just not to comment on potential 'fishing' stories. No attention, good or bad, and it's less likely to continue. It's really not fair to post negative comments, with just a suspicion. Some people will get lucky, not to mention there are hundreds of tips, tricks, and 'best' locations posted here, to help the new people be successful quickly. Lot of good information for a new hunter, to get the right equipment, and plan their first hunts.
