Alter71

 

 

A metal detector with the capabilities demanded by advanced users, but provided with preloaded settings which make it ideal for beginners also.

 

The Alter 71 detector can not only be used as a static detector for very deep low frequency work, but just as effectively as a rapid, dynamic detector for locating small non-ferrous objects using high frequencies.

 

The flexibility of the detector is enhanced further by the option of dual mode, using the benefits of motion and non-motion mode simultaneously.
