Whites DF Question????

[mickfin]

Dos Whites DF have a problen in Black sand?? And Salt??? Is it also ok in Fresh Water can you Disc out stuff a bit, Like Bottles Caps / Pull Tabs / Rusty stuff,
With the Pulse Delay with out loosing a lot of depth??? Thanks all, Mickfin

the Dual Field is made for salt water, although there are varying degrees of how much the machine will be affected by it. Changing the Gain, Threshold and Delay acts to smooth out the noise that salt water causes while still allowing good depth. The same goes for black sand although this is a very dense electromagnetc envornment that no detector can work it's best in. As with any machine, turning the DF down allows some degree of performance--probably better than anything else out there, although a smaller coil would be ideal for this type of environment to reduce the amount of material that signals have to be separated from. Hope this helps.

It has no real problems with black sand or salt, but you do have to know your settings and turn it down a bit while going through dense black sand. As for trying to discriminate out targets using the pulse delay, it generally will work to eliminate bobby pins and rusty nails, but you still get bottle caps, but you also lose so much depth just from turning it on that there is no point in trying. Not sure how it would work in fresh water, though it does very well in the dry sand, aside from the no discrimination thing, so I'm guessing it would work alright.

Do not use alot of pulse delay unless you don't mind losing small thin gold rings and such... I'm hunting a beach with quite a bit of black sand and instead of running my gain at 3pm I turned it back to 2 pm and it smoothed out the threshold very nicely... your not going to discriminate out iron... the signals will just be softer... I would not use the DF in freshwater.. get yourself a VLF for that....

Hey Clives.... havent see you on for awhile so im going to take advantage lol. I was interested in the DF as well. Does it have multi tones to help pick thru targets so you arent digging every tiny piece of wire? Would you recommend a DD coil over the concentric? In the water are small coils better if you want to slow search an area? Is it more productive to do that as apposed to covering more ground?

The DF is a 1 tone machine... saying that one can discriminate by ear... wire/nails and some bobbiepins have a scratchy double beep.. as to the coil its hardwired.. the 12 inch coil is like 2 coils in one... and you PP with the small 6 inch inner coil... I know I'm not clive but I think I can answer your questions the DF coil glides very nicely through the water...

You will find yourself digging steel because small brads, screws, washers and nuts will give a strong, single signal without the double blip of a longer bit of steel IE wire, nail, hair pin or perhaps a long screw.

Snap tops, screw caps and regular bottle caps give excellent signals as well. Aluminum nuggets from cans etc melted in beach bonfires are another source of strong signals even when they are small bits of metal!

I would be lost without my Pro Pointer on the beach as the tiny bits of metal are hard for my old eyes to find. In the water I use a Vibraprobe for pin-pointing after I use the coil to check my sifter for a target.

There is no easy way to discriminate the target, but educated guesses can be made from the quality, size and duration of the signal tone.

Mostly if it is not a double blip I dig!

Heres something straight out...The DF is for the serious hunter that doesnt want to miss a thing,you dig everything therefore you finds are more...I have the minelab excalibur aswell,the excal has knowhere and near as much depth in the water or on the sand and I really mean that,it handles the black sand better than any other water detector you will ever get and you will be digging up what others have not detected...I bought clives book and read it about 5 times...it does take a little to understand the detector at first but its the deepest water detector in the world and you need to have genuine detecting passion to understand it...I have read tons of stuff on this forum and all the guys here are genuine people that give genuine advice....

I have found 1 blue star earring on the bottom left corner of the photo which was about 1 inch in depth with my excal which was a bloody faint signal and with my DF I have found the rest of the stuff some at depths that just boggled my mind...You cannot compare the sensitivity with the DF

 

[Craig-PI]

CJ... I don't dig the double blips because its mostly surface junk, I understand about small screws can't do anything about that... I also don't dig large signatures (long wide tones) sure hasn't hurt my gold finds I give you alot of credit using a pinpointer I could never use one on the beach I put 1/4 hardware cloth in the bottom of my scoop plus a small magnet if it goes thru that its most likely not worth chasing... beaches I hunt are loaded with tiny 22 cal bullets and I pick most of them in the bottom of my scoop... wish I knew why I find so many bullets on my hunts lol...

 

[amberjack]

bullets on the beach that weird, sinkers maybe

my whites DF PI just cleared customs and from reading this thread i will be digging deep and finding some good stuff cant wait.

cheers

Doesn't everyone find bullets? I have alot more than this... it will give you and idea though... I average 6 per outing...

Craig, the pin pointer helps me quickly find those pesky tiny bits of metal that I would never see otherwise. They can give a strong signal and I don't want to dig them again!

I need glasses to find my glasses these days, but I refuse to wear them on the beach, because I don't want to get down on my knees to be close enough to focus on small stuff. Therefore, Pro-Pointer it is.

I fund all kinds of bullets in the water and very few on the beach.

There are too many year-round homeowners living at the beach now for people to target shoot cans and bottles in the water as they did years ago when the beach was deserted in the winter.

True story.... years ago a friend of mine who water hunts had a friend who was waterhunting one of my favorite beaches... it was about dusk and this guy heard something whiz by him and noticed some unsavory types onshore taking pot shots at him... it has calmed down a bit (police always around)

 

[Cupajo]

This has been a quiet area for the fourty years we've been here, but these days anything can happen.

Wonder how they would have reacted if he had shot back?

CJ

 

[amberjack]

far out that's not something i have heard of amazing shooting at people like that wow!

some of those slugs are big bore too,

i am in Australia and our gun laws are very strict have to go out the bush to use guns and that has changed a lot now. need all sorts of licences to have one don't even see gun shops any more.

If the D.F. was really made for salt water Whites would have included a SAT control. Unfortunately instead of biting the bullet, as with the Surfmaster P.I.'s which either had a pulse delay OR a gain control but not both, Whites again has failed to include a vital control leaving it up to third parties to make it the detector it should have been in the first place.

 

[amberjack]

i have a question does the DF PI run chattery all the time on the threshold?

i just got mine today and if its going to chatter like that all the time i may go crazy i couldn't get it to run smoooooooooooooth it was bouncy or chattery no matter what i did, can i back the threshold off to silent?

machine works well just that noise................any help would be much appreciated.

 

[Craig-PI]

Don't expect a smooth threshold it does chatter but the chatter can be smoothed out by adjusting the gain and a tiny bit of pulse delay... you can also quiet it down with the threshold...

I usually run my threshold at 3 pm but a beach I have hunted in the past requires me to tone it down to 2 pm because of chatter...

Even if it does chatter a deep whisper can still be heard but you must be focusing on your detector... I listen for the slightest break, its almost like a blank spot in the threshold these are your deepest whispers and most likely a keeper target...

 

[Cupajo]

Another thing that may help too is to add a layer or two of dense rubber gasket material to the ear cups to tone down the volume a bit.

I was driven to distraction by the tone until I "turned it down"!

I'm still able to hear everything, but it isn't driven into my skull!
