F75

The F75 is full of good features, light weight, only 3.5lbs, double D coil, long battery life, backlit display, large simple to read numbers, selectable tones, manual and trigger ground balance, 4 process modes, and it ID's in all metal. That is just to name a few. In most cases you cannot run it with sensitivity at full bore, and it was created that way. This detector has hyper sensitivity, in most cases in my mineralised ground I can only get it up to 60 to 65 out of 100, and still obtain phenomenal depth and results.
Many detecting enthusiasts won't admit it, but they don't understand sensitivity on a detector, they think the machine HAS to be at maximum sensitivity to get the best depth and results. WRONG! What you have to do is understand what the best setting are for the spot you are searching or you will not get good results. Too high of settings result in endless chatter and jumpy displays, also target masking. Adjusted properly you will be amazed at the results. For one example, in a very trashy spot I had to set my sensitivity at 30 (out of 100) to get it stable and still pulled a tiny 3 piece officers cuff button at 7" plus amongst the trash. Proper ground balance also has a big effect on results, and this needs to be set properly, sometimes even every 15 minutes of searching. The F75 is not for a user who is too lazy to read the manual, and tips, and reviews. It is VERY simple to use once understood. I think some people may have some trouble in their soil if VERY highly mineralised, and still fewer may receive a machine with a glitch in the circuitry.
