I'm impressed. Its the updated MD6027 version that I received. I've had a couple sub $100 detectors and other than the 130ft rating I wasn't expecting much better performance... but wow. Its detecting iron in all metal mode 2 to 4 times further than the cheaper detectors. Its heavy but that's necessary to withstand water pressure at 130feet underwater. Its mostly aluminum and very sturdy. Others complain about always attached headphones but they fail to understand what it takes to work at a 4.90 atmosphere depth. Especially at this price point. The control software, tones, rotary controls, multi-color indicator and sounds all seem well engineered. It seems to have and extra long shaft that will help get deeper in the water without having to dive. I find the tones much less irritating than other detectors I have used. People complain it has no gold mode. But that is just a gimmick used on cheap detectors. Gold and Iron detect the same. I cant wait to get more experience learning the operation of this detector looking for treasure on the shores of Lake Michigan.
