X-terra 70 Coils Question

[BamaBill]

I apologize if I'm rehashing a topic with this one, but I'm trying to figure out if I need to add an 18.75 hz 10.5" DD coil to my stable for relic hunting. I already have the MF 10.5 and it works ok in moderate to bad ground, but I hunt good ground too and I wonder if the higher freq. coil might not work better on deep bullets and small buttons in good ground. I noticed that a higher freq. detector picked up the head of a target arrow better than the 7.5 khz coil. I think that thin metal head is similiar to what a detector would see if over a CW button.

Far be it from me to try to answer your question but, I have found my smallest earring and ring with my 6" HFDD. The baby ring is just a touch over 1/4" in diameter. It was about 4" deep.

Thanks, its good info. I have the 6" HF as well and its a great coil in a real trashy area.

I've worked the 5x10 in areas I have hunted with the 10.5 mid frequency, and made finds. I thought the area had been hunted out, and I'm pretty sure it had, being a real small area. But it never hurts to try another frequency, one of the great things about the Xterra. I may get a 3 Khz coil and give that a try.

Hea Bill you don't need a 18.75 kHz coil for hunting relics that coil is made for hunting GOLD

Get the 10.5" 7.5 kHz DD coil that rascal will get down deep in the ground and is great on seperation & mineralized ground
