If its the PI Pro (yellow box) try setting the sensistivity to 3:00 position and the threshold at 10:00.
If there is too much "chatter" at the 3:00 position, try 11:00. It Is NOT a sensitivity control, where "more" is "more sensitive". We also turn up the volume inside the box. On the black cover over the circuit board, there is a small hole, and a white screw down inside. If you turn it COUNTERCLOCKWISE you will INCREASE the volume.
Hello new here just purchased a new surf dual field have been detecting since i was 18 now retired looking for some help with this new machine. I have dug many fish hooks a few coins all new and many lobster trap parts bobby pins etc am i setting something wrong. All help will be appreciated.I hunt in NH and mass all the beaches .
Even though the detector supposedly has only 1 tone you can hear subtle differences in it... bottlecaps sound like iron does.. a wider signal vs narrow sharp signal for a pulltab or ring, coins are a higher sounding tone I know when I'm over a coin with this higher tone with my old PI PRO everything was the same except for the iron which again was a long drawn out tone... nails and wire have a choppy broken signal... when you are over a bobbiepin you can get a good signal in 1 direction so X the target and if it breaks up its probably a bobbiepin..
Ok settings I like running all my detectors hot... a PI threshold is never clean or smooth so a little extra chatter doesn't bother me or affect the performance of the detector saying that I run the Gain on/off at 3'oclock which is almost full bore I run the threshold right around the factory setting but do turn it up a little louder when its windy, I leave the pulse delay at the factory setting
One final thing listen for narrow targets longer sounding targets are most likely junk and I don't dig them... they are not going to be a chain because PI's only see 1 link at a time, they are most likely trash targets... I haven't dug a good target yet that was a long drawn out signal.

What you are calling off is actually the factory setting so its on by turning the pulse delay up you start to lose depth on the really deep stuff but you will also eliminate small pieces of can or foil but again will lose deeper nickels and gold... so I leave it alone at the factory setting.
Both the Gain and Threshold control, control the sensitivity... you can read it here...

The factory setting for the Pulse Delay, all the way off is 15 useconds. For most type of hunting, leave the pulse delay in the off position which is also the preset position. However in areas of very heavy black sand, you may need to increase the pulse delay a small amount to make the unit run smoother. Craig PI is right that both the Gain and Threshold control the sensitivity. The Gain and Threshold control does not affect the Pulse Delay control. On wet and dry sand, I like to run the Gain at the 3 o'clock position and turn up the Threshold until I can just hear the audio. A course this all depends on how much electronic interference there is at the time I am hunting. In the water if I am hunting an area that the ocean bottom is uneven, I reduce the Gain down to preset. But if the ocean bottom is smooth and there is very little wave action, I increase the Gain until I get falsing and then back off the Gain a small amount. Here is a picture of my last gold ring found. 14K with three 3/16 carats each diamond, weight 10.2 grams. It makes a nice pinkie ring for me!

I have never run a machine like this i am sore from digging. Lots of junk no rings beer cans at 15 inches plus. I hate people who bury cans and the signal is like a good coin or ring? I will try the settings I have seen here and let you know what happens hopefully will have some pics to post.
In salt water I have to run my sensitivity setting low. You kinda just have to play with it. Set it about 1/4" from the on spot and then set the other setting (can't think of the name of the other knob) until you either just barely hear a hum or to where the hum completely stops. You will get false readings when waves come in but you can fine tune the sensitivity knob to minimize that. I probably won't go away though. You will just get used to it. I really like mine but it will work you to death. Every piece of metal will sound off. Of course, in the water you want to pretty much dig every target anyway. It does go way deep.
On land it will really wear you out. I wouldn't really recommend it as a land machine.
I have the PI Pro and an Excalibur 1000. I hunt mostly with the Excalibur but if the area is pretty clean I will hunt with the PI Pro. With the Excalibur sometimes I feel like I am passing over things because it discriminates.

I have the Whites Surfmaster PI Pro. I had the older Surfmaster for years but gave it to my brother when i got the newer model. So I'm familiar with both.
The major differences between the two are:
1.) The pulse delay has been shifted to make the machine more sensitive to gold. This is basically the same as some of those aftermarket re-calibrations that you read about.
2.) The Gain knob on the PI Pro moves opposite to the Pulse Delay knob on the old PI. On the older model you would turn on the machine with the Pulse Delay knob and then leave the knob bumped up (counter clockwise) against the stop for optimum performance. On the PI Pro you turn on the machine with the Gain knob and turn it clockwise to increase the sensitivity (and depth).
The drawback to both of these things on the PI Pro is that the threshold can become extremely unstable which interferes with the ability to hear very deep targets.
On the older model the threshold was rock solid. This enabled me to set the threshold right to the edge of audibility, thus giving me the ability to find targets very very deep. White's Surfmasters have an audio modulator tied to the signal strength which allows the machine to actually talk to you with a infinite number of subtle tones ranging from a loud harsh ping to a soft tiny squeak. I used to go to certain beaches and go very slow and only hunt for the little squeaks, which were usually very deep gold or silver targets.
On the newer PI Pro the constant background chatter makes it impossible to hear the squeaks with any reliability. But the machine is much more sensitive to gold which is a welcome trade off. I experimented with the settings, realizing that with the PI Pro would never go quite as deep as the older model. Increasing the gain caused an unstable threshold causing me to lose targets in the chatter, decreasing the gain caused a loss of depth. For the last few months I have been running my PI Pro with the gain on maximum and the threshold on minimum, basically hunting in a silent search mode. Since then, I have doubled my quality finds. The good targets ring through just fine and I find that I am also digging less trash. As for depth, I am routinely digging good quality targets at 10+ inches deep.
I'm currently trying to get my brother to give back my old PI as he rarely uses it. I will probably only use it to hunt for very deep objects in those known deep productive areas.

I also use the PI and lots of junk but some coins but not many. Tried it in fresh water works just as well lots of digging but some coins no silver and no gold yet. This machine is a worker my friends want to know what I joined a gym for at my age 59 looks like i work out daily. Well just had to add a few words. I am still trying to figure out how you folks search in salt water in the water if the tide is high its too rough and at low tide you can walk out am i thinking something wrong or not seeing the whole picture?
