This is the top of the line Fisher Labs metal detector.  It took all of the great things about the F75 and added more great features such as BOOST and CACHE Process Modes.  It also comes with two coils - the great stock 11" DD and a 5" DD.  This is the machine I use first.  Get one before they run out - these are not in regular production - thus the name Limited Edition. 

More Info From Fisher Labs:

The acclaimed performance of the F75 had people convinced that single frequency technology was streatched to the limit. But now engineer John Gardiner has taken the F75 another leap forward with a more powerful microprocessor and new DSP code implementing two new signal analysis algorithms - The BOOST PROCESS substantially increases depth under most conditions, and the CACHE LOCATING PROCESS is designed to find large deep objects.  The F75 is already considered by many to be the best all-around metal detector available, regardless of price.  We made the F75 Special Limited Edition even better.
