F-18 ? :nerd:

Thats not the pic we are looking for. ;)

T2.. F7??
 
I am not convinced that detectors that operate above 10Khz are the greatest thing for general hunting. My experience is that they drop off too much response wise on those iffy deeper dimes compared to the CZ's ect. Someone is going to have to prove to me that the new f-75 is as good on deep silver as on relics! I have used the X5 and the MXT and for rehunting older sites for missed silver they just don't get it for seeing the tougher iffy stuff.

So is the new Fisher any better than the others?? will it pick out the iffy silver that the CZ's and Explorer find on occassion when hunting "pounded sites"?? With the DD coil I am sure it will pick out some stuff in iron that other top guns might miss, but I seriously doubt it will compete with the CZ's on those deeper silver targets. Not trying to start a war, just stating my experience with the higher freq machines.

Personally, I think the idea that higher freq detectors aren't as deep is a myth. It may have some theoretical basis but I think there are other factors that are more important in practice.

There are just too many machines with reputations for exceptional depth that use higher frequencies: Nautilus, Tejon, T2, Compass, Cointrax, LoboST, and others.

That's my take on it anyway.

neither the MXT or X5 regardless of coil size or configuration (concentric or DD) can hit is not a myth.

Thats only one example and the T2 apparently is no different based on honest reports received from people I trust.

You are correct in that frequendy is not the only factor but it is part of the equation. According to top detector engineers the 10-12 Khz range is best for good sensitivity to a wide variety of conductivities but even then that is not always the case. The Deleon is a prime example of that.

a couple dealers found out it was an inch or 2 deeper with the brown donut coil. They hyped that in the mags and all over the internet. :lol:

Both "high" (above 10) and low?

But, I'm sure your CZ is a fine detector with great depth.

All I said was that many detectors with reputations for very good depth use higher frequencies. So, I think it's not true in practice that lower frequencies always give better depth.

EC,

I'm not disputing that fact that higher frequency detectors can give good depth. Under good conditions I pulled dimes at 12" with the X5 and they were nice smooth repeatable signals. Thats nothing to sneeze at! I hunted an area that had some fill added at one time and happened to have the C$, Advantage and 1270 with me that day. I went thru the area with each machine in turn re-covering my foot steps and hitting it from different directions. There were wheats, dimes and one piece of silver jewelry recovered from this small area all in excess of 12" and all 3 detectors found their share. I was digging every weak signal and none of the detectors really knew what the target was before it was dug. Some sounded broken like a weak partially disced out iron response and on the C$ the ID read high when it could ID at all. I learned a lot that day about what happens on those deep marginal signals with each detector. It was fun!

I usually hunt in a relic type mode listening to it all and at old sites digging it all but I am primarily after silver so I am always looking for that detector that can rehunt sites and find old coins left that for whatever reason have been missed by other detectors. My point is that I have not found any of the higher frequency "relic or dual purpose" detectors that can do what the better coin machines are capable of which is hitting those previously missed high conductive coins.

Tom
 
To say, 'many detectors with reputations for very good depth use higher frequencies' might be correct in some places. But, as with most things in detecting blanket statements can be misleading to the average user. I hunt in PA and for the most part the lower frequency machines are better in depth. I've done some field testing of low vs. high frequency machine that I've owned. I prefer the lower frequencies for coin shooting. But, the higher frequency detectors can pick out smaller and low conductive objects better than lower frequency detectors. Even beyond frequency, coil type and size has alot to do with depth around here. It really depends on the type of metal detecting you are doing. Bigger coils don't always translate into more depth. My T2 is deep but not as deep as some of the lower frequency machines I've owned... at least in my area.
