Multimax overview

Among Multimax's current lineup, the Multimax stands out as a ground-imaging system for commercial survey crews working large sites. Headline numbers: a detection depth of 16-20 feet.

In practice, the standout parts of the package are multi-channel pulse ground balance, extreme search depth and interchangeable search coils. That combination is what makes it worth a look for geologists and treasure-hunting professionals.

It's made in Turkey, and comes with a 2 years warranty.
