Question on coils for xterra 705

[oldkoot]

I have been contemplating purchasing a new coil for my 705 but am unsure as to which one to buy

been looking at the 15 inch coil-tech coils in the MF frequencies and the HF frequencies

What I am trying to accomplish is to gain some more depth as well as more stable target ID
Contacted a couple of dealers in AZ and one suggested the mid frequency 15 inch but me being the person I am I do not go with the first suggestions I get I like to be able to way all my options

I have looked at some of the NEL multi frequency but am a little leery of using a coil that does all three frequencies as I do not know how that would mess with the electronics of the 705

i really like the coils I have but use the 5x10 HF the most and run prospecting mode around 99% of the time

I might be better off purchasing a different detector all together but just not sure at this point

any and all thoughts are greatly appreciated

Thanks for reading
