Equinox Series Handbook by Andy Sabisch
Have not read the whole book yet, but it has been very informative.
The handbook is a wonderful resource for information, hints, tips and settings on the Equinox. The Minelab user manual has valuable information, however, the handbook will elevate your understanding of the machine to the next level. I recommend the book for anyone that wants to get the full use out of the Equinox series of metal detectors.
Enjoying the book many useful tips. Super impressed with the speedy shipping.
