........if the choices for a good " all around" PI unit were between the White's PI PRO; Tesoro SANDSHARK; and Fisher CZ 20 which would be the best of the lot? Which would hit best on gold jewelry/ Which would handle salty marbled black sand the best? What can you tell me about the various traits of the detectors I'm looking at.....tell me what you know from experience. Thanks for all replies.
 
Well, first the CZ20 is a VLF, it is very good overall for fresh and saltwater and you can discriminate with it, it is waterproof, is not the greatest on small gold items. Is expensive.
I would forget the Sandshark, they lack depth and sensitity on small items.
The White's is good all round, no discrimination, dig everything, you can get used to sounds and tell some of trash, will probably handle black sand the best, is best price.
IMHO
 
Hello,
I own a Surfmaster PI Pro since march 2003. I found any kind of ring/coin/trash you can immagine.
It is a great detector in my opinion.
Here are the problems/defects I faced:
1) Whites delivers new detectors with poor quality control.My last 3 detectors I got from them had all 3 the plastic waterproof cable connectors of the head loosen (and I mean LOSEN, they did not even fix the plastic bolt). So always check the connectors for loosen bolts (attention must be used not to tighten the bolt too much).
2) The supplied cable retainers are good for nothing. You'll have to fix it by yourself (I used tape).
3) The elbow cup nut and bolt tends to losen and I lost it! I suggest to replace the original with a inox nut and (self locking) bolt.
4) There is a reinforcing aluminium strip on the bottom of the plastic control box. That is meant to hold the two inox box latches toghether. That should be replaced with an identical inox one or electrolysis develops!
5) the two control knobs on the control box are too loose. They tend to accidentally move during search or when carring the detector around. You have to take care of that or you'll end up with exhausted batteries during transport!
6) Use tape to fix the batteries in the battery holder because they may slip off the holder somethimes.
7) Take care of the "water turbolence" effect since this is a 15uS detector and is very sensitive to water movement. See my preceeding post on that.
<img src="/metal/html/glasses.gif" border=0 width=15 height=15 alt=":geek:"> The head "flips" up if large , strong, waves hit it. This is due to the shape of the head. I do not understand why withes did not use a better shape (see Garret's,Minelab's etc..). It is not easy to move the head in the water.
The GOOD NEWS:
A) Very sensitive unit. No problems on small gold. It just misses small chains as almost all PI detectors do.
B) I succesfully replaced alcaline batteries with NI-CDs . It works a wonder.
C) The control box is easy to open and service and the O-ring seems to be well done.
D) As far as I understand , it is the best detector you can buy for your money unless you buy a unit from Eric Foster.
When you order a PI PRO specify a "weighted head" if you want to search in the water.
Cheers
 
Hi John,
I would go with one of the detectors designed by Eric Foster. I don't advertise for him but from my technical knowledge they are a much better choice than White, Tesoro or Fisher's. But make your own opinion and scroll down this forum. Read some of the posts...There are a lot of happy owners of Eric's detectors.

I would agree with you! My answer was at his choices and were all waterproof, so thought that might be the reason for selections. I have Erics detectors, but have used two of the ones he listed in past.
 
!!! I did not read the user manual carefully! You're right. It is anyway a painted aluminium part in my pi pro and corrosion is developing on it!! <img src="/metal/html/shocked.gif" border=0 width=15 height=15 alt=":shock">
Thanks!!
Cheers
 
Hi Luca,
If you belt mount the unit it will help stop the corrosion. I picked up a nylon luggage strap at Target for around $6.00 bucks and its takes a lot of weight off my arm.

Hello Terry! <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt=":)">
Thanks a lot for the picture!
I agree that you take weight out of your arm but I do not see how corrosion should stop since, in my opinion, corrosion is due to inox and aluminium in contact with eachother. Just add saltwater... <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt=":)">
I already use a belt to carry two pouches, one for the trash and one (zippered) for good finds.
Fortunately I have no fatigue on my arm due to weight.
Anyway if find hard to move the head in the water. It was easier with my old PI3000. Whites should redesign the head shape...
Thanks Thanks Thanks!
