In as much as 99% of my detecting is on our Florida beaches, Minelab gets my nod...both Excal and CTX. Multi frequency machines is the only way to go for me. As for PI machines, yes they're great on saltwater beaches also but given that I'm about to celebrate my 70th birthday, I don't relish digging 20 inches down for a bobby pin...especially in the hot Florida summer sun.
I've tried many different machines including my XP Deus (which design comes very close to state of the art in my view) but I always find my way back to the Minelabs...and I'm eagerly awaiting the fielding of the Equinox as a light weight travel machine and back up to my CTX. If it does well on the beach, I'm in.
Just the view from my foxhole..
As a side note Steve, I'm new to your website and really enjoying these forums you've put together. Outstanding job soldier!!
