This post will most likley be taken off but how can they claim 12 inches....What soil are they testing it on. How deep can the F75 go. They say the F5 for about half the price of the F75 goes 12 inches! Is it as fast as the F75? Maybe they should not have leaked out the news so early till some test were done. And anyone that has a F75 will want to know how they compair. The F5 has a different Freq in the 7 range that is good for clad but not that great for relics. Maybe it should be called a coin machine where for me the F75 seems to do it all.
 
you have to remember.....it comes stock with a pretty big concentric coil.............versus the 75's DD coil. (concentrics tend to get better depth than DD coils do)..The 75 will get a 12 coin easily as well, but its doing it with a DD coil............and will get (I'm betting) much better separation than the 70 will get. The 75 will get a 12 inch coin with the little concentric shooter coil! (In good soil under good conditions).
The 75 also has more operating modes. I think the 75 will remain the flagship machine for some time. Diggin coins isnt the tell all on machines anyway. I think most users use their 75's for relics......AND coins..with the emphasis on Relics. I'll take a higher freq machine over a lower one anyday..........as it makes the machine predisposed to be hotter on lower conductors (read: gold and buttons!). I think First Texas's mindset on the 70 was to make a simpler to use.............easier on the budget ALTERNATIVE to the 75.Its Not meant to compete with it or replace it.
I'll keep my 75...........but think the 70 would make a great machine for my girlfriend...or anyone that may be a bit challenged by a machine that has more than a few options to choose from.
 
the reasoning behind coming out with the F70. And, I can attest the DD coil of the F75 will hit a coin at 12". I've not dug a coin that deep yet with the smaller shooter coil, but it will hit em down to 8-9", I do know. The F75 does go deep and as you mentioned, does get great separation, which, makes it an excellent coin shooting machine as well as for relics. Hh jim tn
 
Hello Lorenzo,

Here are a couple of reasons the F-5 may compare equally on depth or even detect deeper than the F-75, First off is the 10" elliptical Concentric coil and second the detector operates on 7.8 kHz which is geared more for coins.

Plus, This lower kHz may even help stabilize target ID on deeper targets. Lock on stronger and less (getting fooled) on smaller size foil and bits and pieces of aluminum reading as a deep coin, And very possible less falsing on smaller pieces of iron.

On the other hand, The F-5 with it's lower kHz will not fare the same as the F-75 as an all purpose detector. This is one of the several areas the F-75 will surpass the F-5, Over all the F-75 will still be the flagship with the F-70 right there beside her.

Plus, The F-75 and F-70 will have it's place as a stronger relic detector and for other purposes as well.

I tought I heard the DD coils were deeper..If thats the case I wonder if the F5..F70..coils will work on the F75..if not and its a deeper coil wouldn't It be better if Fisher labs would make a concentric Coil for the F75 mostly for relic hunting.I am getting lots of reading with the small 6" coil coin shooting at a local park good vdi and audi signal in the upper 70 range at 14" to 16" when pin pointing so I figure there in deep.The place is 1700, 1800 ish...I didn't have the digging tools but I will go back.I am impressd with the little 6"er...
 
EXCEPT in poor soil. In very bad soil a good DD will often get much better depth than a concentric. In relic hunting type sites though depth isnt always the most important thing you need in a machine. Separation is....and DD's have it all over concentrics in terms if separation. General rule of thumb though.....................in regular soil...when separation isnt a factor.. size for size a concentric will best a DD in depth every time.
 
I would bet the 7.8kHz WILL find the relics deep. I'm using another multi Freq coil detector with a 10.5DD 7.5 khz coil that has found minnie's & buttons at 12 inches..............
 
IMHO, exactly right. After considering both machines, the F-70 seems to be "coin-hunter orientated" leaving the serious relic detecting to Big Brother. The F-75 has already proven what it can do and now with those credentials, enter the F-70. The CZ-5 and CZ-3D were 2 of the deepest discriminating coin machines that I have used..saying that the F-70 will find coins at 12" is a step forward...I really believe they will sell to the detectorist who isn't concerned about relic hunting... BTW, with the 70 and the 75 running the same freq. at 13khz, the coils will be interchangable..
a concentric will fire up the F-75 a little more where the mineralization isn't bad...Best to all, Richard...
 
Hello Liquid,

Steak is correct....Generally, Concentric coils (size for size) will fare a bit deeper over a DD coil in good soil. Under harsh mineralized conditions then the DD may surpass the concentric on depth, And most DD coils will excel on separation over a concentric.

I don't think the F-5 coil will work on the F-70 or F-75, Different kHz coils. However, The F-70 10" elliptical concentric coil will work on the F-75 and I believe the F-75 coils will operate with the F-70.

cool info thanks...I took another look at the F5..It kinda is built like my wifes Titan 2000 XD which is a good coin,jewlry hunter..It will hit at 6" to 8" no probs even more with steel and pinpoints to the round coil easy....It has the 2 9 volts and the housing looks the same..other than that the F5 is for sure a new animal....I will be intrested in a new F70 coil for the F75 if there not to expensive..It might be a good tight place in woods coil..
 
The F75 has found me silver, gold, it is deep and fast and has a lot of programming. It has out hunted a lot of big name brands that cost more. It is great at hunting in the hills of the Gold Country, at school and parks. I would not buy another Fisher unless one is as fast and a lot deeper and I really dought that is going to happen in our Calif dirt. I also won't send my unit in to fisher for the new seals...I would hate it to come back a little less hot who knows what they might fiddle with. And we should not have to pay for something they made a mistake on. That never has happened on my SUV.
 
Well in Calif it is the F75 that will go deeper because of the soil. And maybe they should make us a new coil that goes deeper. I still think it is hype not all soils are alike they don't say how fast the detector is if it is any good at unmasking in iron how it works in trash. I think Fisher maybe should have waited on the F4 and F2 and put money into giving the T2 and new coil and some more coils for the F75 their flagship...but time will tell and then we can see how good these new machines are.
 
and you are not paying for stuff that is covered under warranty. If wish to return your F75 for a new hand grip and battery contacts, it will not cost you anything. Those items are covered by your warranty. The $50 upgrade is simply for the weatherized enclosure, an option if you so choose to have it done. They wont be be doing anything to the electronics.
 
that is the same thing Bush said and look what happened!
 
I have read somewhere that the new sealing is a totally new plastic housing..anyone with any info ..thanks in advance..I am seriously thinking about sending the unit in..My time to hunt is limited and I will feel better if its water proofed..A good drizzle in the woods causes alot of condensation..for any unit..
 
Hey scully....can you contact fisher and find out for sure. There needs to be clarification here. Some dealers are saying tha handgrip and springs will be takin care of under warranty, however if your grip is fine and you want the new grip....Im hearin from some that its $50. Some are saying its the weatherized display is $50............... So what is it for sure?
 
and both said the same thing: if the girp is not bad they would not replace it. Both questioned why anyone would even send a machine in just to have the grip done, especially if its not bad. The $50 cost is for the weatherizing. If battery clips and grip are bad they will replace them at the same time.
