Need PI to detect larger items at 1-3 feet and ignore small stuff

[kharrar]

I am mainly looking for metal items in Privies; you see I am a bottle digger and have found that almost all privies contain metal items. Usually these items are pieces of pipes, horse shoes, buckets, cans, etc. almost all are iron and are heavily rusted. I would like to use a PI for there depth pot entail and a fairly large coil? Maybe over 1 foot in diameter? 18 inch? Found a good deal on a headhunter PI but it only has a 11 inch coil and is set up for coin finding? Could I get a detector that I could change the place were the pulse is sampled to be able to detect more larger iron items? These items are usually about 1 to 3 foot in depth.

Thanks in advance for any help,

Karl

From what I've been seeing on the forum the TDI may be the ticket...

Another Detector you may want to look at is whites ULA-3/Sierra Madre which uses 15 inch coil claiming depth of up to 5 feet.
The price range around 600.00$

TDI with the delay at 25 will not get all small iron away...but can raise the coil to check for big deep iron will still signal seems to work well deeeep!
