I have a Garrett at pro that has the stock coil on it. I was considering trying out the 5x8 coil but was curious just how much depth would I be giving up and coverage would I lose?. I’ve read so many positive posts as well as negative about the smaller coil. I hunt pretty much every condition between trashy sites to not very trashy open fields. I guess my question is would the 125 dollar purchase be worth it? What do u at pro users recommend?
