I Love My 3kHz Coil!
- Thread starter Old Longhair
- Start date
Should be available through any MineLab dealer. It is the only LF (low frequency) coil offered for an X-Terra, and only made by MineLab.mmattys30 said:
Loss of stability. Loss of depth. Usually when GB numbers are too low.
I've run into areas where GB was as low as 3 with the 3kHz, and it didn't do well. Switched to a 10.5" DD and got GB numbers in the upper 20's, so it was a better choice for that site. Then I just needed to pay better attention to the nuances of the higher tones due to the narrower high value bin widths with the HF coil.
Typically, I like GB numbers to be 20's or better. Usually in that range, I can run the SENS @ 24+. When GB drops into the teens (or worse), I generally have to back the SENS into the teens to maintain stability, at which point I figure I'm losing depth.
Someone else may have had a different experience, but this is what I've found.
