Must be a little easier on the arms to swing too. Them old minelabs were a bit heavy. I compare my E Trac to the CTX and there is a big angle of grip/balance difference. If I use the E Trac, I can really feel it after a full hunt. I hear a lot of people use their water machines for relic hunting.
Am comfortable with the weight of the explorer. I've built up the the muscles.
Got an ACE 350 and that feels like a toy in comparison ... Weight wise that is.
