PI-based detectors are not very good at discrimination because the reflected pulse length of various metals are not easily separated. However, they are useful in many situations in which VLF-based metal detectors would have difficulty, such as in areas that have highly conductive material in the soil or general environment.
A good example of such a situation is salt-water exploration. Also, PI-based systems can often detect metal much deeper in the ground than other systems.
Just an interesting online statement that i read a while back on a 'how it works' site. But you probably already knew that but im gonna post anyway. :D ={~#

Hello sparrowlegs, I think two of the important factors affecting, are how serious you are about going down the PI route versus your budget. There are some details concerning the pro's and cons of using a PI machine in this link. Good Luck with your decision making. ::g

A disservice is no service at all.

A decent first PI detector is the CS4PI for not too much money whether new or used. What's your budget?

Hi Sparrowlegs
I had a Whites Dual Field Surf PI machine and it was the absolute bees-knees. Paid about £650 brand new for it and ended up PX it for a Safari with cash deal. You may pick up one of these second hand nowadays for about £400 maybe even cheaper.

I had great fun with as it punched very deep but be prepared to dig everything, and I mean everything. Hope you find what you are looking for.

Vallon Vmh3cs off eBay.

Spend the rest of what you can afford on a sand scoop.

In addition, I like the plastic soil trowels from B&Q for about £2.50 for digging in sand, you can wave the scoop over the coil to see if you've dug the signal.
