ctx / pi combo

[destructo]

wondering if anyone uses the ctx to clear out an area and then uses a pi machine or blisstool and tries to get a little more? D

what nobody actually tries this? or are you afraid to put on the forum?

In some mineralized soil a top end pi will detect deeper than the CTX, I know of a fresh water river 100 yards from my home that an upper end pi will detect deeper. We've got some tough river sand here in my area of California.

But out in ocean water comparisons should fare about the same,

I have just begun to start using a variation on this,but as i dont use a ctx you can infact use most detectors to do the same function i use a DFX with a Hotshot coil on to clean the area first then when most of the junk is cleared or you have reached the maximum depth on your vlf detector/coil combination then its time to use a PI with a large coil to gain the extra depth.

Of course i dont use this for everyday detecting but only when you suspect a possible hoard or coin spill that type of thing but you have to way up the reward to effort ratio and work out if its worth it.Generally it works very well i mark out a small area with some 'hi viz' markers to define the area this could be say 50ft x50ft then use the VLF/PI combination to clear the area.
