I know the itch when a new machine hits the market. Honestly, I went out on a limb to buy the F75 early-on. I have no regrets. Yes we all like better info on a target and depth and that is why the 'hunted out areas' are fun to pull silver or gold rings out of. The thinking goes that newer is better. I wish Microsoft would come up with a OS that was as robust as my F75. I really do not know how they will top the F75, but I am sure they have ideas. The machine is fast, deep and offers all the info I need at a glance. The final choice is between my ears on targets that do not ID due to depth or masking. Any of a number of machines are great for the guy who doesn't want to get their knees dirty and bends over for a sure thing on the surface. Looking back over the last 12 years or so, there have been some great machines put into production. I bought some of them. I think the high end machines are for the TH'rs that want to recover what was passed by. There may only be a few inches in depth advantage in some models. I also consider how technical the machine is and simplicity of use. One thing for sure is the extra info is desired by those hunting on the edge of detection. Many of us detect with little or no discrimination because it is a well known fact that discrimination is costly on depth. The F75 in AMM is so powerful and quiet that it is my favorite mode. The two coils are all I really need and are nuts-on as a single frequency machine. What is sad is that while the grass may look greener on the other side, the F75 is overlooked as old technology. As for the limits of depth with any machine, a matched coil (load) and transceiver just cannot be beat. ML knew that with the 'terras, and it was not a gimmick to sell more coils. At first glance the F75 coil looked a little funky but the configuration makes for a powerful coil optimised for one frequency. Stay with the f4 frequency when you can (default). Maybe there is another machine in the works but I honestly cannot say the F75 is 'old hat'. It will be a long time for me to go back to all those 'picked clean' areas and see what was left behind at the limits of depth the f75 delivers. It detects way into the pulse range for some targets and though you may not have ID numbers, the discrimination can be done in the audio quality and only gets better as you near the target. Yes, I am PRO F75, it kicks my MXT in the butt in so many ways and the MXT is an awesome machine, I guess I followed the designers because I know what they can do, they know what they can do and most importantly, they know the design limits to get the best performance in one configuration. How the F75 can be topped is a wonder to me, but there is always hope. remember,, function before aesthetics. Both are a sweet deal in the F75.
