F 70 Too hot of a machine for California???

[Waterdog]

I think I want to get a Fisher F70, but my friend told me that they are to hot of a machine to use in California. Has anyone ever had any issues with one ?

Not a matter of too hot for CAin my opinion. It's probably more that the friend has the sensitivity set too high for CA mineralization. I used to live & detect there. Now a forum member you may wish to contact is..........Low-Boy/LCPM......... He tests units for Fisher, lives in CA and is extremely knowledeable on Fisher machines.

You may also want to direct your questions to Cal Cobra (Brian) he is a very knowledgeable detectorist in northern california

Thanks Rick...........I forgot about Cal Cobra..........Oooops!!!

thats why they have threshold and sensitivity adjustments! To taylor your machine to the local conditions. I have a couple of gazillion hours on the F70....(but use the F75 and F5 too)..........and havent found a place in the States you cant use it.....and that includes that nasty hot old Va soil. you just have to compensate for it. It may not be the absolute BEST machine for a particular enviroment.................but CAN be used.............

I don't know that LowBoy ever used the F70, but I logged a LOT of hours on my F70 in Northern California. I found it to be an average machine. With the 11" DD and 5" DD it did OK, but not spectacular in our mineralized CA soil. It did OK in iron, and was fairly stable, but depth was lacking for me. I made some nice finds with it (nice 1840 seated half dime, and my best piece of jewelry), but none were that deep, maybe 7" at the max.

Personally I think I'd go for a T2 over the F70.
