Nokta/Makro just trying to keep up and surpass the Jones with new products. The Kruzer and the Anfibio are just two product lines at different price points with different features. No different than buying any other line of products. For example, looking at fishing reels a manufacturer line can go from $25.00 to $400.00............
Buying an Anfibio, nothing not to like about it, doubt the resale value will dwindle just because Nokta is coming out with a simul. muti- frequency machine sometime in the very near future. Don't worry about losing on money spent, it will pay for itself in short order. And really nothing not to like about the Anfibio, it really is that good of a machine, don't think you will be selling it too soon once you see what it can do and what you can do with it. And just a big tip, get a 7" concentric coil for it. By the way if you try the Anfibio for a good month to learn the ins and outs with it, you may be selling any other detectors you own. It can replace many...... Happy Hunting when the weather breaks.
