Just my 2 cents on this topic:
As some one that had been away from detection for 30 years. I decided to get back into it, so you can look at me as a new be if you wish but with experience with single freq. Shopping around/watching videos/ comparing what others think/reviews is a wonderful tool now days in today's tech world. A machine that can go simplex and multi freq., makes an advantage for an all around machine. I realize when a manufacture says this or that about other manufactures like the word "obsolete" it hurts feeling to thous who have good proven machines, but need to realize it's very true if you really want to be honest with technology and advancement. It costs lots of money for new tech and advancement for companies to manufacture new lines of equipment. Some will stay ahead of the game others will stay the course there on to squeeze every penny they can till they can't. I think that's about where we are with some of the good companies that still run single but have good tech in them. When I was in my 20's single freq., is all there was. 30 yrs later is a game changer to help or hinder you, depending on your knowledge and seriousness with detecting. I don't think it's perfected yet but a new page has turned.
