My I think simple question is. How much more depth % do you get in Mono on a pulse machine? Ie TDI,GPX

I don't know the answer but I do use both TDI and GPX. I only have the standard coil that came with my TDI. With GPX I use DD, AI (Anti Interference) and Mono. Using the same size coil the least depth is with the AI coil, the deepest is the Mono followed by the DD. I think the % difference is variable depending upon a multitude of things like ground, wet or dry conditions, target material, target size and shape etc..

I will use the best coil for the conditions and type of target I'm looking for. The difference may not be much between DD/Mono but using a mono for a little extra depth could be the difference between finding a really good target or passing it by.



Happy Hunting

Thanks I do relic hunting in Va. and have only used the DD. It is a hunt that they have twice a year and many of the sites we have been to more than once. I was thinking the Mono may be the way to go to find targets that we have missed with the DD. I use the 4800 at those hunts. Thanks Jim
