I Use a Discriminating machine but dig 98% of all targets and dump all my trash, i fill in my holes and remove trash because its harmful to others, Plain and simple
if you can pull the treasure out then you can also remove the trash
its a yin and yang thing happening there, The ocean gives you some treasure as long as you do her a solid and remove some trash is how i see it, and as for the holes
Man its a public place that others use day and night, so yes someone will fall in your hole and hurt them self 100%
no matter if there mother told them to pay attention or not YOUR HOLE LED THEM TO HAVING A BAD TIME AND GETTING HURT AT THE BEACH
I am the type that will always say something and if i see others on the beach doing so i give them the benefit of the doubt and offer my advice on how to better conduct your self as a member of this hobby, if that doesn't work well most have seen i can really be a pain in your butt if ya dont want to follow the rules lol
And before anyone chimes in on the other 2% , well these are the weak tiny foil signals or straight out nulls for iron that get passed but even then most of the time i dig em to remove them and not have to find them again later .
