Was wanting to see if any of you guys have been able to compare all three coils or even just the 3 and 7.5 in the field. I am primarily a coin hunter and was wondering if there is any advantage of one over the other, for just coins. I would assume the 3kHz would be good for cache hunting for large deep objects. The 7.5 would just be your multipurpose coil and the 18.75 would be better for the smaller objects and gold. I have used the 7.5 on my X-Terra 50 and I have the 18.75 I have not used as of yet because I have sold my 50 to get a new 70. So, wanted to ask you guys. If I am just going to coin hunt and maybe an occasional relic hunt. Do I really need the 3Khz coil. Would there be an advantage in it for me??
Thanks in advance for your help?? Mike
