Just started using the Ajax Primero and I have to say this thing is on another level. The build quality is excellent, and the amount of tech packed into this unit is seriously impressive. The multi-system modes and 3D ground scanning are super helpful for identifying different types of targets, and the depth it can reach is wild.
It took me a bit to learn all the features, but once I got the hang of it, I was finding things that my older detector completely missed. If you're serious about gold or treasure hunting, this is a fantastic investment. It's powerful, professional, and worth the money.
