F-75 LTD beach hunting for jewlery question

I am going to be concentrating on a particular freshwater beach in the area as soon as my scoop arrives. I mainly am interested in pulling as much jewlery out as I can with limited time. What numerical reading would you concentrate on? I have air tested several rings with the following readings:

14K gold chain -19
Triton Titanium ring-34-35
Platinum ring-31
white gold ring-35-36
wife's diamond ring-22-23

If the ring is on it's side, the number seems to go up 2 or 3.

From what I have read, JE mode is very sensitive and perhaps the best mode for my hunting. I came to the conclusion after my air tests, that my best bet would be to dig anything between 19 and 36 or so, for my best chance to come up with some rings. Also, run in 2F and dig repeatable tones, even ones that tend to skip around. I have heard advice to dig ALL repeatable tones at the beach for jewlery.

Does anyone have any experiencial advice to give? Numbers would be welcome. I have recently been digging just 19-36 repeatables. I have been finding foil, tabs and nickels, which I know is good because that is were the rings are. I have not found one yet, but know I must have perseverence. Thank you for your advice for this fresh water beach hunt. I plan to spend all day there when I can, take it slow. Also, where would perhaps be the best place to focus; just inside the water line, up on the beach where people lay, etc. Eventually I want to get the CZ-21 to get deeper into the water, but the F-75 is the best I can do for now. Thanks, Bryan
 
I would dig anything that beeps or wants to beep from 13 on up. Not all jewelry will give you a repeatable signal. If you put a strap on your 75 you can venture out in the water safely about 2 feet. The strap is only if you drop it. It can be a simple cord from the machine to your belt loop.
 
I have an F70 that I've successfully used on the freshwater beach and shallow water...and theres another poster Ayeti that has found a lot of gold this year with an F70 on the beach..you should pull up a few of his posts...

Foil and tabs are your friend...any scratchy bad signal is too...you will get to know all of these real well if its a good active beach that hasnt seen a coil...you dont have to dwell too much on a signal and figure out if you want to dig it, just DIG it, after a while you will get to know what everything 'probably' is on the first ping......experiment a little, you may find AT is the best for you, or else a low disc like 4, mid/high sens, and as many tones as possible so you can hunt by ear and not have to look at the screen...hit it hard super early before everyone gets there, once the sun is high, that screen will blind you like its a mirror...first of all, you have to figure out if anybody has worked it recently, the targets will tell you that in short order, and if so, hunt off to the sides of the main beach...dont worry too much about depth on your first few initial passes, you just want to figure out the traffic patterns and all that, ...!
Good luck!

You might get a better answer and suggestions on the Beach Forum if you posted there too....

Those guys are really into all things beach hunting... and do know their stuff.
 
I just did a test of numerous rings that my wife has. The small gold rings, including her diamond, all read 19-23 range, with my wedding band 50-54. All readings are an average and VERY jumpy. That was a good revelation for me. Expect jumpy, and dig the iffy signals. Thanks for the advice, and yes I did also post this in the Beach Forum. Thanks.
 
If we only had a unit that could detect gold chains in salt water sand, at depth.
 
I do a lot of freshwater beaches(lakes ,rivers, sand, pebbles) with the 555-D, 1270 and the F-75, If I were you dig every signal, pull the junk up and just keep going over the same areas over and over again and from different direction,and start with the 5" and clean that out then goto a larger coil and repeat everything over and over again, If the waters in the lake you'll be going deep especially silver coins and jewelry. I'm on the 3rd year at a local beach in my town (1940-1975) just about done but I get a deep (9" or more) MERC. All Metals, Sen as high as you can go, or 0 Disc if unstable with the F-75 , same with the 1270. The Fisher 555-D i don't listen for sound just watch for needle fluctuation, got tons of deep small rings like that. Anymore info I can give just ask.

I agree, it the area is know to hold gold, dig all repeatable tones regardless. I've found nice gold ring that registered a solid 25, well below a nickel on the F75.
 
Here are the readings that I had during a test, buried 5" in my yard:

wife's diamond wedding band-20-22
my wedding band-50-54
about 6 other small gold rings my wife had all fell between 19 and 24

I found that all signals were very very jumpy, but the numbers above were the predominant numbers. Also, I found that because of EMI, I ran sensitivity at 30 and still received very strong signals in BP mode. DE could pick up very well too, yet not quite as strong. I even put a tiny gold ring on its side at 5" and found that I could barely pick it up going one direction, but the other direction I would get a loud double beep. I even went to sensitivity 20, and in BP mode, still received quite a strong signal. Fascinating test, particularly on the jumpiness of the numbers.

I air tested some other rings and here is what I came up with:

14K gold chain-19
Triton Titanium ring-34-35
Platinum ring-31
white gold ring-35-36

If the ring was on its side during air testing the numbers would go up 2 or 3.
 
Make sure you do another test at the beach...sand is not at all like dirt...and the moisture content changes all the time...at least up here where we have miles upon miles of open sand...tie a piece of string to some gold rings, do some test burys, and give that a go...deep dry sand is tough, if theres any black sand at the waterline, that can be very tough, the signals will not be like on the dirt at all...if it rains on top of dry sand so that only the top 1/2" is wet and underneath is still dry, thats a whole nother situation...beach hunting is tough duty...if you have a really great spot, you will clean up...if not, you can go a long time between pings.
You are preparing properly!:thumbup:

Thanks, my trip to the beach to put the F-75 to the test is approaching rapidly. I am taking all of the advice you all are giving to heart. Thanks again, there is nothing like experience!
 
Wear reflective or very dark sunglasses. This way you won't get caught checking out the fine scenery frolicking around. This is one great perk of hunting swimming holes and beaches.
 
The #1 beach hunting Rule ..........Dig all Repeatable targets above iron.......... If you use any Discrimination other than iron, you pose losing some Jewelry.............Also zinc penny range are where the Large heavy set Rings fall in, and there the ones with the big diamonds ....... iffy foil Range could be a chain ............Good luck
 
Thanks for the great advice. Well, I took the F-75 to the fresh water beach. I planned on spending about 4 to 6 hrs detecting, but had to quit after 2 1/2 hrs due to malfunction. I found $3.81 in change. No rings. This particular lake is used by tons of partiers and four wheelers. I found that every swing was LOADED with foil and mostly pieces of cans. If I was going to find a ring, I would have to dig all signals, which would be thousands of holes. Too much for me. I finally just focused of coin signals, nickels and quarters. I took a break, then decided to go in the water a foot or so. I swung for about 5 minutes and decided that I would go back in dry sand. My detector started acting very erratically.....water had entered the coil somehow. I had to send it to Fisher for repair. Sad end, had to cut hunt short.
 
There is no substitue for quality control.
Seems I remember some threads back a while about Fisher coils leaking because they didn't get the required amount of silicone. It never crossed my mnd to warn you to hit the joints and cable connection before submerging it. Not many attempt the 75 in the water.
 
I ordered a Beach Hunter ID 300, so now my F-75 coil will stay dry.....ready for some surf hunting soon...my first time hitting this part of the beach!
