whites surf pi pro dual coil / verses Garrett sea hunter mark ll

I really don't like the Surf PI Dual Field.
 
Its deep as long as you haven't tried other pulse machines.
Lacks a SAT control so not good in black sand areas.
The paint finish on the shaft (black) doesn't seem as good as with the older Whites water machines.

Perhaps worse, and I'm a great fan of Eric Foster designs normally, his Duel Field coil combined with the lack of a SAT control makes I.D. of targets very difficult.

The plus is its cheap for a waterproof detector.

My other pet hate is the Infinium. Beautiful build quality but o the problems over the years. Again a cheap machine now but started off at a ?1000 plus (sterling) then gradually dropping, ?999, ?929. ?695. Stock coil to big and heavy and the discrimination depends not just on high/low tones but in combination with reverse discrimination/adjustment of discrimination level etc. By the time you have done all the checks you could have dug out the target and been on to the next one.
Has anyone mentioned that most beaches require the discrimination to be set to 2 or 3 to balance out the salt ? At 3 sensitivity to gold is starting to reduce. Very slow sweep speed required so less ground can be covered and if near a big beach resort you may well have to switch to a small coil.

Roll on the day of the waterproof Pulse Devil !

Went to Hampton beach with DF first time out dug a few nickles from 12" to 20" deep you really need to be quick when digging down that deep holes kept filling back in fast! As for cjc Say's he can tell caps and junk from the good stuff? I did start to hear the difference in the audio double beep for bobby pins and rusted nails most of the time. The lobster trap bits so so some seem to sound good then other pieces sounded rough when you do hit a good target it sounds crisp solid audio response with a sharp clean ramp in the audio on targets less than 12" deep on the deep targets the audio ramp was smooth even ramp up and back down the same both ways. Hope this helps some one that might be thinking of getting the DF

Also the DF was set to the gain max, pulse off, threshold just above audible.
