advice on setting up my LTD F75 for Beach use

[pacis888]

I own a fisher f75 LTD, I did this when I was younger, wow how thing's have changed, I do hope to learn from everyone. My brother, is big time into this metal detection, he recommended this site, since I have a fisher. I do have a couple questions, I do mostly beaches, I went today for the first time, but I could not ground balance it, so I set it to 10. it seemed to work fine. I was having a frustrating experience, my ltd was picking up from 81-95 at about 16" deep, my problem was, I could not dig any deeper than 10" I kept hitting this seaweed bed at 10", the signal was very strong, this is a relatively obscured beach and I was getting strong signal every where, just could not dig beyond that 10". QUESTION: would anyone advise me as to the settings I should be using for beach use. I did bury 4 items all different on the beach and the LTD found all of them and the only sounds I was hearing was that of different metals.
Would appreciate any advice. thx

Do you have any experience with hot rocks on land ?

This procedure by Mr Tinfoils, will help as much as possible.

1. Put it in all metal. Set Sen. to 80, Threshold to -1, and pull trigger and push button till you get it to F7. This way machine will run quite for you
2. G/B, manual G/B that is. it will G/B around 6 to 0 depends where you G/B. I just go down to the wet sand not the water wet sand and G/B. Usually will G/B out around 0. Remember there are 5 clicks between each number and this is important at the beach.
3. Now when you sweep you might get a little whirrr sound, don't pay any attention to it. It is just a little ground flutter due to the wet salt sand if you are in the wet part.
4. Ziz Zag find the coin line. You know that.
5. Now this is the most important part after you get things set up. Small bad iron targets will give you a BaDa audio. Large pieces of rusty iron including bottle caps will give you a loud BAAAAAAA audio. I son't know what the green hienikin bottle caps sound like so you have to figuare that out . Let me know what audio you get in all metal on them.
6. Good targets above iron or 15 ID number will give you a Zip Zip audio every time. Unless the target is on edge it will read close to the regular ID numbers as long as you get the target centered. On edge the numbers will jump a little. Just go ahead and pinpoint the target and dig your ass off.
It is really fast even in the wet sand. The only thing I get in the real bad black sand is that little flutter but you should run pretty smooth. Anytime you get a Zip Zip dig the target. I don't even look at the ID unless I hear a Zip zip zinc audio and they will hit around 45-50 with a nasty Zip Zip. Dig a few hundred and you will hear what I am talking about. I don't dig Zinc's when I am in a hurry. The Gold Zinc Zip Zip is different. A lot smoother audio. You will really be surprised at the targets you will dig.

YOU REALIZE THIS IS THE JW FISHER FORUM - TOTALLY DIFFERENT COMPANY THAN FISHER
JW DOES NOT MAKE YOUR MACHINE
IT MAKES DIVE MACHINES MOSTLY

 

[woof!]

Casper's confused, this is the FRL forum, not the JWF forum. You're in the right place.

On a beach, do your ground balancing in all metals mode, that way it can balance all the way to zero if necessary in order to knock out the wet salt. In disc mode it won't balance below (as I recall) 40, because in disc mode you don't hear everything and you could inadvertently balance on a piece of iron.

thx so much Rick, much appreciated. As I mentioned, I was getting that zip really loud and the depth was at 13-16", really strong, it went into the nickel-quarter range, but due to that damn seaweed bed, I was unable to get through it. what setting do you use in the Disc?? the notch and sensitivity for this mode? I learn pretty fast. for disc level what is the sensitivity and the notch, I do 98% beaches. I have the disc set right now at 29. How about the # of tones and the process, what should I use?
could you run me through on how you do your manual GB? also when I get an object and push the trigger forward, what is your procedure?? what will pulling the trigger do, except give you the depth?

hi rick

Them settings definitely do not work....have tried many times.

Only thing I can get to work that is tolerable is DISCRIM 6....SENSE 60 ...BP MODE ...AUTO GB OFTEN.......

KEY THING ---- SMALL COIL.

Does AUTO GB even work properly there ?
ROMEO 1 said those instructions helped him ?

One thing for sure, salt water, and high mineral are tough conditions esp. for machines not designed for it.

Auto ground balance won't GB to salt. You should ground balance it manually. I'm not near you, but down here, salt GB is 0-20.

Hi Rick,
are you saying I should be using the smaller white coil that came with the unit?? right now, it is bouncing all over the place, with your settings, never stabilizes at all, it will jump from, 16-95 in a blink, can never seem to get a solid steady read, so the small coil is the key to this?? I sure hope so, I am getting a bit frustrated, chasing after ghost all the time, so far, dug up about 100 holes and the yield has been , 1- penny and an aluminum tab, something is not right, please advise.
thx pacis888

I have heard the same I don't know which smaller coil u have but I have heard the circle 5" dd is impressive just about the same depth as the 11" & easier to tame that beast with. The 6" elliptical coil I've heard does lose some depth & not as powerful as the 5" for whatever reason but still will be easier on the beach. Definetly manual gb, sensitivity 9-21 might do it

hi
I just got off the phone with fisher, spoke with a nice person, about my F75 LTD for beach use,
he informed me that the test he has done is, he was using the 12" (11") coil DD, he sets the sensitivity to 55-60, disc at 15 using the DE mode not the BP, he does not go by the read out, he goes by the sound, a good steady sound and uses 4 tones. He said as long as you have a consistent sound, dig it.
I mentioned using the 5" DD, he said the 5" would be much more stable and would go down to a depth of 8", he said you would cover less ground, but it would be more quality/quantity than covering a large area with the 11" DD coil and it would eliminate much trash. So in a nut shell, strong steady sound, not the reading but the consistent sound, dig it.

 

[christo000]

Good info & absolutly correct I've used many machines a lot of them were supposed to be high end & even those sound has always been what you want to go by if you go by those screens ur gonna miss a lot if great stuff, thanks for the update for us

Hey Rick, hope your well, I got down to the real truth about the F 75 LTD, it is simply not made for the beaches, no matter what you do. I went out a bought me a MineLab E TRACK, it's incredible. If you ever want a real good place to buy from, go to Colonial Metal Detectors, cmd@colonialmetaldetectors.com, Rich owns it, he's super trust worthy.
The first place I went to was metaldetectors./com, ask for Rich and mention me, Richard from Maine, he will treat you very well. Anyway, metal detectors, lied to me outright about the F75 LTD, I told them I was going to do 90% beach and they recommended the F75. I called Fisher and they we're really upset about that. So long story short, I did get my refund back, did my homework and to my surprise found out my brother has been using this very same MineLab E TRACK for the last 5 years, he loves it and has made a ton of money with it. The very last time he went out last fall, he found a pure gold Crest ring, he got 2K for it. The ring was 12" deep on the beach and was actually suck on an iron bar. FYI

I've had the limited for three years and never been to the sand, sorry.
