Mud you make me bust out laughing 
I'm thinkin' like A***65 you be stirring the pot -- love it. But -- listen up all you clad heads -- about finding the really deep stuff -- I read an old article by TOM DANKOWSKI'S and way back when, he was using a Fisher CZ and using a 10.5" coil hit silver at 14-16" That dispels the formula that the max depth of a coil is the width of its circumference -- don't it -- I mean if you thing he is any kind of authority, and I think everyone that has read him much will have to say, he is some kind of Metal detecting genius in the field. He also has a lot to say about comparing detectors and the factors involved in testing, testing and testing. He goes through all of the variable and considerations, one of them being "bias" of course. There are things to consider in setting up a test to decide which maker is making the bestest macheen -- made my head swim and made me realize the endless comparisons are just that -- endless. So, let's assume all makers of metal detectors are equal in their ability to make a machine to consistently find that silver dime, or half dollar at the same depth -- what would be the factor, then, to consider as a choice of arms? Well, price, would be one, then visual appeal -- even if it is an old beater with a Hemi in it, even those types of sleepers have a beauty in the eyes of some. Next, I think, would be weight, after all, a heavy machine could wear you out before your time. Then a screen that is readable at arms length. Then something with excellent battery life -- who has not hated getting out in the middle of an hunt and see the battery bar drop to one bar? Well, guess what, the Fisher F75 and F70, have all of these qualities -- the battery life is truly unbelievable compared to others. My hunt buddy has a White DFX, a real battle wagon, and hand to hand weight comparison, I feel cheated, after all heavier feels more expensive and means you get more right? Only in the meat market. How they were able to get the F75 and F70 so light weight and balanced with such power is amazing. So, all things being equal in the find department, the F75/70 top the list in easy of use and this translates into more finds, not necessarily deeper than other top of the line machines. Once I understood and trusted the speed of return on the signal, out and back, of the F70 (the one I own), after listening to Mud, I started finding more and more often -- this machine likes to go fast. What is fast? Well, it ain't slow, only when you hit on a target then pinpoint it and dig it. Now, where can I get my hands on a CZ 3d? Oh, and an empty field full of deep silver?

. I happen to swing the F70, never had the opor to swing the F75 but while research the market for an upgrade from my F2 I looked hard at the F75 ltd and man I was slobbering all over myself, but the price -- I tried really, really hard to justify the gold it would take to buy it. After a lot of crying and some begging, she still said NO! If you know what I mean. Then, sulking off with pouty lip I cruise about and saw the F70, how similar it looked, a real cutie, and I realized, after a couple of hours of more research, I found I was falling in love all over again. Fishing around for a price, I found one -- not as good as you got Revier, but under $600 and with the 11" DD coil. I go to mama again and praise her for being so frugal -- she gave me a thoughtful, loving pat on the cheek, then I told her I had found this other love and at nearly half the price. She gave me pity permission and like a real man I ordered this cute little trick and 30+ rings later (13 months) and I plead the 5th on the rest, I am still thanking the little lady for letting me take on another love. Is the F75 better? It is definitely a premium detector but when people ask what I paid for my F70 and I tell them they kinda cough a little but they don't roll their eyes back into their heads and nearly pass out. What do I care anyway, if I would have come up this the nerve I would be swinging the F75. Not sorry, not sorry at all, my finds with the F70 have consistently turned up more coin than my hunt buddy with the DFX ($1200) that he felt there must be something wrong with his coil so he bought a new coil ($200+). 
-- I hope those fellow Fisher friend do too. Everyone, I am outing Mudpuppy -- he is kidding -- not speaking for you Mud but somebody has to save you from being burned -- oh, wait, you love it don't cha. Mud and Revier set me straight early on in my pursuit of the unknown and between these two you could not go wrong listening (closely) what they say. There are a couple of other guys too, Elton, and Kieth and others but I would have to say that Mud is my mentor, even though he might deny it, still -- cheers mud 
One good thing though, she sure didnt mind me going out detecting after that! And, She has no interest in clad, which I get to spend on beer and smokes! 
Still, the advice to start with what some call a starter machine is still valid, besides, the plus to this, is if you decided this hobby is great and fun, then when you upgrade to something like the F75 you have a loaner, or backup machine, or, as in my case, one your wife can use, or anyone interested, or sell it on ebay. By starter machine, however, we are not talking about some off brand cheapie but something like or equivalent to the Fisher F2 and F4. By the way Roland, what is the weight and the battery life compared to your F75 - just curious.
