Man, I do not know where you are getting that % stuff from, but if I were you I would check my sources and if you have any reservations on the quality of the Fisher products maybe another brand is more your comfort zone. Call around and see where you can get an order for Fisher products filled by model type and ask yourself ,"Why are they so popular"? Shop for a F70 because they are a real bargain. Another brand might be more available % wise. Most of all, shop for a machine you can afford and you are happy with based on values you define. There really is not a whole lot of hoopla with Fisher products, so if that helps in making the decision, buy into the hoopla. This is a hobby and should be fun. Whatever equipment you own is a choice YOU make based on values that are important to you. The F70 is a value for the money and function.
The new F series machines are making their owners very happy and most have had other machines in the past. Some own all the latest brands. It is not easy to compare apples to apples, but one thing is for sure and my F75 has awesome speed processing the targets for ID and giving a good report with impressive depth. On some targets it is still a crap-shoot and unless you dig, you just do not know what is there. If you just want to get coins on the surface, you can knock'em dead with many brands. For deep silver and the 'hunted' out areas that are still producing: get an F75. Hands Down.
I have heard that the relik hunters in the SE states are going for the new Fisher models and there just might be a reason they are not advertising it like a bunch of Kansas City carpetbaggers.
I also was told the Fisher groups are the fastest growing population by brand. Of course that could all change if something new was on the market, but at this point Fisher is king of the hill, top of the food chain. I would question anyone who would question why you want a Fisher.
Wade, I hope you make a choice that most of all you are comfortable with. We all like the things we own and want to make decisions that are well informed so that our pride of ownership is not tarnished by misleading facts and buyers remorse. In this forum you will find happy owners who have a genuine enthusiasm for the products they bought. As long as there are products, there will be issues and as far as I can tell Fisher takes care of the squeaky wheels.
In my opinion, look into customer support before you buy because that has allot to do with being a happy owner. Another opinion of mine is,.....
Best to you,
Sunny Jim
