seawater any input welcomed

[sube]

If you try it and don't see any improvement turn it off as it can create additional problems ( straight out of Andy's book ) .

Well my ? is why I hear this all the time but no answers .

I live in a state that they spread tons of salt on the roadways the roads turn white after they dry all that salt gets snowplowed to the strip of grass along side the road , Also where ever the car sits the salt drips off on to the grass . The fairgrounds I hunt have activity's all year long ice racing bikes 4 wheelers and so on people park every where on the grass in the fairgrounds with salt dripping off there cars and depositing on the grass where I hunt . As you can see how many pounds of salt end up on the curb strips .
I run with seawater on and it does control the jitters ? is does this have anything to do with all the salt that is deposited on the grass . Now looking at curb strips with all that salt laying there and a good rain what do you think happens to all those ferrous targets laying there I would think they rust at a faster pace than ground with no salt giving more jitters to the problem .

I've been running with Seawater ON most of the time now Sube. Especially if I'm running Manual Sensitivity,it does take the edge off the chirping in MY experience. You're rationale is sound,IMO. We are in the same salty boat...

I wonder if that would also help in farm field that have been fertilized for the last 50+ years.

Wasnt he talking about the beach dry sand? You would of course loose some sensitivity to smaller targets. I believe thats one reason he recommended turning it off when on the dry sand.

Good thought...the school I hunt was a farm field through the 70's,but right next door to the old school grounds. Even the older Memorials have started to "powderize" already so there has to be a lot of old fertilizer in there. I don't think any soil is naturally that vicious! All we can do is experiment before we dig,which is sometimes hard to do...but Seawater very well may help here.

Well farm fields get limed all the time which lowers the ph to make it more alkaline where they say to use it such is out west .Then again they say if you need it .

that's what I was thinking that you would loose some sensitivity to rust flakes mineral hot spots hot rocks or just plain ground noise . I personally don't see a difference in depth on a dime using the same sensitivity running with it on or off but it runs much quieter . With it quieter now I can push my sensitivity 2 to 3 numbers higher than without it enabled and this gives greater depth where as if it was not enabled I would have to run at lower numbers reducing my depth .But then again there are places I don't need it .
Good point on loss of sensitivity
That brings us back to Why turn it off on dry land that's the ?. sube

On a beach you are looking for gold. Like most multi freq machines the CTX isnt the best choice. BUT.... add a salt setting and its doesnt help matters. On land..... it will depend on what you are looking for and soil conditions. Different ball game id say. You just arent looking for targets in the foil range.

I did do some test along time ago with targets that read in the foil range 12.01 to 12.03 there was no difference in the signal enabled or not .Which led me to think that it was not doing any harm these were in ground . Still have that ? but thanks for your impute . sube

 

[Mr. Carolina]

Dew: I'm curious what machine you think would be best to hunt gold on a beach? PI ?

 

[dewcon4414]

Depends on the beach conditions. Too much trah will pretty well make a PI useless and to time consuming. I assume you are talking about IN the water. I believe the Xcal once learned with a PP switch is the best. Its just a simple machine and once matched with a good pair of phones and straight shaft is as good as the CTX. But....out of the water the CTX Is better with the tTID, depth, and faster recovery. Dry sand a good many singlr freq machine will out perform the multi freq machines.

 

[Mr. Carolina]

Dew: Thank you for your response. My question was more aimed at your comment, ( On a beach you are looking for gold. Like most multi freq. machines the CTX isn't the best choice.) This threw me a little as on the beach more than likely the CTX is the best machine IMHO. I have pulse machines for the treasure coast and barrier islands of Virginia. I have Excaliburs for the water and the CTX for the wash and damp sand. 38 years detecting and I still can't walk in that dry sand! Lol

 

[dewcon4414]

When i say not the best choice...... im talking about SMALLER gold thats affected by the salt setting. Single freq machines just do a better job on the small stuff. BUT...... in the water/wet sand it is what it is with a required salt setting. Its like a PI having a Us of 10 vs 24. IF we could get a good PI that would give us some reliable disc most of us would put the VLFs in the closet. The CTX has a very reliable TID and great depth....... but i think a lot of beach hunter walk over a lot of gold ignoring 12-01 targets after awhile. Anything of size i will agree the CTX will find it.

Sube..... its not the 12-01 or 02 that you are getting...... its the ones like small gold earrings, chains and charms that you dont know is there. BUT...... is it even a concern or worth the time? The Xcal will hit on a piece of gold .3 grams so i assume the CTX will as well.... if its 14K thats what $6? To me its like not chasing those targets falling thru the scoop. During recent drop times your beach tactics change with more competition and people spread out more.

 

[Champ Ferguson]

Thing is about some of those $6 gold items is that they may have a nice stone attached to them. At least that's why I am always looking for the small gold when at the beach.

 

[dewcon4414]

Champ that sounds possible.... but rarely true except on earrings. To know that means they were big enough to find. Kind of a needle in a haystack. ... so the time spent may not be worth the dream. The ole saying you dont know what you missed if you never found it.

Dew

 

[Champ Ferguson]

Yeah; tiny earrings with fat rubies/diamonds/<insert any expensive stone here> are my white whale. But I will get one some day.

 

[lytle78]

Here's one that might beat all of the above at the beach. The bad news is it's not a production machine – it's not for sale. The good news is Fisher hired the developer and acquired the technology and we hopefully can look forward to new developments from First Texas products based on it

Here's a video showing one of the prototypes on a beach with a fair amount of mineralization. The detector is a pulse induction detector but unlike most PI detectors seems to have a usable iron discriminate function. It also seems to be able to detect nonferrous targets even when beneath iron.

The video is in French but I think it's pretty easy to follow what they're doing - all metal mode - two discriminate modes, multitone and iron reject with nails rejected - gold ring accepted in addition, they show ring detected beneath two nails - and very ferrous Blacksand eliminated in the discriminate mode while detecting the ring beneath.

[dewcon4414]

Champ...... the problem with finding one of those earrings, and i have a few, is you normally just find ONE.....ugh. Someone came up with a good solution. Make a necklace out of them.

 

[Champ Ferguson]

Well, I gotta start with one that has a hi$ stone. Then after that milestone is reached, I can cry about not finding a pair .
