Nugget Shooting with the F75 LTD ???

grumpy

New member
Morning All; I have a question about the use of a F75 LTD in nugget hunting? Any advice on mode and setting to do this type hunting? We would appreciate any tips for such hunting.
Thank
Grumpy
 
Don't know about the F75 LTD. but I use a F75 for nugget hunting and it is a very good nugget finder. With the 6" elliptical coil it is almost as sensitive as the GBII on sub grain gold and is deeper on larger pieces. I have found several oz,s with it.
 
So what is the difference between the 75 and ltd? I thought it was just basicly a boost in depth on the ltd??
What genral settings do you use to find gold on the 75?
Thanks
Grumpy
 
Hey Grumpy!
I recognize those tailings you are surrounded by in that picture.

I cannot tell you about the LTD, but it would be a natural choice if I was to buy one of the two for where you go. The F75 performs wonderfully there.

Here is the strategy out of the gate at the creek: the name of the game on a push is you only want to hit the sure things and cover as much ground as you can, that means the guys using the MXT are adding some discrimination to mask out any iffy targets of junk and rusty iron that falses. The foot racers cover as much ground as they can while everyone else is checking out iffy Targets. You want enough discrimination to get the bang on the ones that are easily hit. Go with a 19 to mask all iron. Mono tone. JE. You can test a nickel as a
 
Using the iron meter on the F75:

The best way to learn this is to test it on sub surface rusted iron. That is, iron that is wet with moisture and rusted underground. There are rocks that are cracked and the F75 can detect the iron in the fracture. You will be surprised at how sensitive the machine is at a hairline fracture that has rust in it. When investigating an iffy target (after the rat race) be sure to check the meter. Now here is the rub: The same iron deposits can be on gold nuggets. There is as a rule, more gold than rust on a good target, so guess who wins? If the iron meter says much magnetic iron is present and you don
 
Thanks GO!
Practice for the hunt. After the rat race. F75

You will make a test garden with iron trash and some small beaten up split shot. You can get an assortment of split shot with different sizes. Split shot has some points on it; natural nuggets are not uniform shaped targets. Mash some small ones flat and make a mess of the others. Throw them in your test area. Just pitch them all over the place. Now you will need some scrap iron for trash. Torch off the coating on a coat hanger, cut into different lengths up to an inch (notch it up too between cuts) and soak them in a bowl of bleach for a day or so. Drain them, let air cure for rust in a humid environment. Soak again. Let them get good and rusty. If you want to do steel tacks, that works good too but try to stay away from nails hot dipped in zinc so you get rust.
Pitch the rusty stuff all around the lead.

Now you will hunt for gold. Turn the sens. way down to near nothing. Try the discrim of 6 (F75) and JE.
The lead will give the sound you need to learn and trust. The iron tells another story. Try different settings and modes. What happens when you go max sens? The lead will give you readings and a sound that when you hit a nugget in the field, you will not miss. Learn what to expect in readings from good targets. Try sweeping from different angles and heights to see the weak signals and then move in closer. Try the same targets at a an iron mask of 12. Try it again at 19 or 20. Are you still hitting them all?

Pay attention to the iron meter. Now locate some of the iron (you need a magnet) and lead and make mixed targets together. Try one lead to several steel targets.
Gold can read in at 6 to 80
 
Nuggets are very unlike coins and bullets and buttons because of size and shape. If you practice with one target you will miss the ones outside of the box in the field.

Equipment is as important as strategy. If you detect in a group, you may very well run into coil bumpers. You can be working an area and they sweep in thinking they will beat you to the big ones as you noodle around enjoying yourself. I have seen it happen where a guy moved right in front of another when there are acres to cover. A 3+ OZ nugget was snatched. Any machine could have found it. The quest for gold does strange things to people. You could be 150 feet away and some guy will tell you he was working the area while headed in another direction. I was in a place far and away from the rat race and some fool with a four foot coil on his MXT showed up right on top of me and said I could go ahead and move on while he waits there standing with his noisy coil falsing my MXT. I told him he could move on as I had the same detector and a civil factory coil.

The stampede foot racers will cover the whole push before they slow down. It is amazing what they miss and leave behind on the first sweep. Then they want a new push to do it all over again when there are hours of detecting to be done. Most of the time the guys with all the big nuggets never find small ones. There are more small ones by percentage. So how good a detectorist are they in reality? Greed affects a good time for all except the greedy who relish being the hogs at the trough. You can deal with them by knowing their game and matching them at it. Then they start to squeel that they no longer have an advantage. Well, my friends it is their race and they can only out nugget you if you let them set the terms. There is nothing like planning a vacation to get away into the wilderness from the rat race to find the rats are there too.

The F75 performs excellently and if there is another in the proximity you can shift the center of frequency, but the guy would have to be right on top of you to get falsing. Aftermarket coils can have poor shielding and you can hear them on like machines a ways away. They are junk. I have seen the guys with Johnny Cascades loops but I usually hear them first on a like machine with a factory coil. If you want to bump coils with the F75, there will be no complaint they can hear you and therefore tell you to move on.

The factory coil on the F75 is the best you can get, you don
 
Are you saying that the G2 is a Gold Bug Pro ? I think you are correct.

I've looked at them both and see that they both have the same specs and also have the same housing. Also, the same display ! (see pics below)
 
yepper.
Thanks for the side-by side pics. There might be a few differences in appearance and I am not sure but the G2 might have a different audio report.

It is THE machine either way. Maybe the G2 is styled to the market it sells in. I like its looks.

Without a doubt I would get the GB PRO and not wonder about any differences to the SE or G2.

I would also not entertain what coils are crossed over and work and would only use the coils designed for it, There is quite a span from 13KHZ to 19 KHZ and no way one coil can be that broad-banded and have a tight Q.
I would not want it if it was broad banded, it was supposed to be designed for what it is used on. DSP really is that good though, I wonder if I can detect with my boxspring?
