F-75 just came back from a open hunt

[Rick(ND)]

I had to try this in a competition hunt to see if the F-75 would work at all as the T-2 last years was chattering so bad it was hard to use it. The F-75 worked excellent, no chatter at all, just wish I could have worked as fast as the F-75 did. I used my Uniprobe which was Good as many of the coins were at a angle so the pinpointing was off a bit. I got 3 silver half's, 3 Eisenhower dollars, 1 new Washington dollar, 3 clad half, 1 40% silver half, 9 silver quarters, 12 merc dimes, 14 silver Rosie's and a 1865 silver 3 cent piece. Got 4 of the tokens for prizes too. I found it worked real good for this type of hunting.

One thing this hunt was held at a very old park we have had some nice finds over the years, but it is getting tough anymore. We had a 4 hour break so I tried to see what the F-75 can do. I got one new dime and I know over 30 rusty bottle caps that sure sounded good. I was in the BC mode too with the disc at 6, 4 tone mode and sensitivity at 70. a few of the explorers were finding a few coins, so I ask one person when he got one I wanted to see what the F-75 would do. He got a weak signal he thought was a IH penny, the F-75 read 45-55 as it was bouncing around too, but sounded loud for me. I told him I felt it was a pull tab or piece of one, when dug was a very small piece of brass.I just didn't seem to get my coil over any good coins, but it sure found the rusty pull tabs.I know most the meter will jump numbers bit like 3 or 4 numbers and the tones sometimes will give a different tone, but they just sound too good not to dig. Most now I can call before I dig, so I am getting better.

Just want to let everyone know the F-75 worked good for competition hunting where the T-2 could not.

Sounds like a good haul......
maybe you had one of the early T2's before they fixed the coil? Because my T2 is more quiet than my F75 is....
HH,

Bill,

The T-2 I had was the early one, but was sent in for the upgrades and a new coil after my first hunt with it around other detectors. The T-2 was more sensitive to small items than the F-75 is I feel, but my F-75 is quieter over all running than the T-2 was.I will say before or after the upgrades of the T-2 I never seem to have much problems with rusty bottle caps sounding like a good coin like the F-75 does.
With the T-2 I had even after the mods I couldn't hunt with in 10-20 feet of another detector without getting interference of some sort and if checking a target with others they had to turn off their detectors in order for me with the T-2 to check it or I would just get chatter and no signal. That is why I said last year the T-2 is no competion detector, but find the F-75 seems work good as i got no chatter other than when the coils got within about a foot of one another.

Can you expand on this a little more. Are bottle caps giving you a good coin sound. When you find a target, are you finding if the meter jumps around it may be tabs or bottle caps and when it locks you found a good target?

On my MXT I like to play a game and guess what is under the coil so I dig most everything. BUT... by listening close, I am often right and when I have only a little time cherry pick by the sound. I didn't find the MXT meter to be very accurate which is why 1) I used my ears more and 2) I just bought an F-75 because I'd like to dig less trash.

I read in another post rusty bottle caps are a problem. Has increased experience made those less of a problem?

Thx.

For me rusty bottle caps have always been a problem with any of the Fishers I have used, but never been a problem with the the other detectors. The T-2 gave me a little problem, but was able to tell them fairly well. Now I wonder if it is our ground up here in ND that give this problem or not as not many others complaining on these rusty bottle caps.
To me most will sound just like a coin and I will see some bouncing on the meter numbers 5 or 6 numbers, but also see this with some coins too, so the visual ID is not the answer. Now where I am seeing some difference on some is in the audio as you will see some when coming at a different angle will change tones or even read as iron just for a spit second. I am from the old school that when ever in doubt or not sure you have to dig as this is where some of the best finds are found.
Some of these bottle caps when going to pinpoint i will also see they will sound much louder than they will in the disc mode which will tip me off. Many too in disc will change tones while sweeping the coil over them, or read very good one way, then drop and tone or 2 when swinging the other way in Delta pitch. Now on rusty pieces of tin cans they do sound very good, but when the ID reads 91 or more you know no coin reads that high so you can walk right over them.
With the F-75 I feel most of this is getting to use the detector more and learning it better. About the time I want to believe the visual ID more is when I dig a coin that the numbers bounce around a bit and I thought it was a rusty bottle cap.
What I have been seeing is that the coins that have not been real deep(up to around 8 inches) seem to have a better lock on and the tones seem to be more fuller on most of them. On the Rusty bottle caps and even some of the newer bottle caps will sound good,but the ID will jump more and the tones may change a little more too on the sweep of the coil. I feel when I get more time on it IDing rusty bottle caps may get better from experience with it.
I also have a MXT plus a Sovereign GT and the Explorer SE, my wife's uses the MXT mostly, but I find the ID for me is very good and we do dig some trash, but don't remember digging as rusty bottle caps that sounded like a coin did. My GT will fool me once in a while and read like a nickle if the ground is very dry while the Explorer can fool me more on rusty nails than anything else.
The reason I say I must not got my coil over a good target at this park as the Explorers were finding a few coins and those that got a signal for me to checkout all sounded real good to me and one I remember the F-75 got a lot better signal than the Explorer did, this was a small copper rivet he thought was a IH, but it read too low on the F-75 to be a IH in my opinion, so I had to stay there until it was dug.
On the good note I took it to a park last week that had a trashy area and dug quite a few new coins in with the iron as my disc was set at 6 and I could hear the iron low tones. I think it was around 30 coins in a hour and a half. Took my SE with the 4.5X7 coil everyone says is so good and got 5 coins in a half hour as i had to go so slow. None of the coins were old, some surface all the way to 5 inches deep.
Good luck with the F-75 when you get it and see what you think on the rusty bottle caps if they are giving you a problem or not. I am going to try another F-75 myself just to see if there is a difference or not too.

Yeah, the F-75 found it.<br>
You say about bottle caps, "To me most will sound just like a coin and I will see some bouncing on the meter numbers 5 or 6 numbers, but also see this with some coins too, so the visual ID is not the answer."
It isn't your ND soil as that is exactly what I'm experiencing. I've mostly only hunted beach dry sand, but the bottle caps are a real problem for me. They usually hit between 55 and 85 and can mimic a zinc cent, copper cent/clad dime or clad quarter depending on condition, depth and position in the ground. I hate to waste a lot of time analyzing iffy tones I think may be caps, so on the beach I usually kick a few inches of sand aside and that sometimes exposes the cap (or coin) if not deep. If the F-75 weren't the best detector I've used, I wouldn't hunt bottle cap infested areas with it. I am improving at identifying them, but I wish Fisher could have made them sound worse. No problems with nails, but I have dug a couple large rusty bent ones.<br>

As I said, I've been hunting the dry sand with the F-75 and I can't believe how good it is at finding leftovers. I'm not sure of my hours spent, but I'm about 2 hours into the 2nd battery indicator segment and most all the stuff above came from small well hunted bay beaches. Very good depth with many found at 8" to 10". These beaches read .01 to .1 on the Fe3O4 Graph, ground balance at 79-85 and are beds of nails with melted beach fire aluminum pieces thrown in for good measure. I was constantly experimenting with the disc and other settings, so can't say where they were set.<center>

Hadn't seen one of those LED jobbies (but then I probably wouldn't dring a Budweiser if it was free). I have the same experience with steel caps. They hop around. I had one today that went 80 to 93 in the sweep but 56 to 70 when I crossed the "X". Very inconsistent, but I dug it as tuition in Hard Knocks U.
