What`s the maximum depth Bounty Hunter TK4 Tracker IV can detect? 

That is a loaded question. It would depend on many factors. First how big the buried object is. For example a coin sized object ( Say a quarter ) may get 5" where as a garbage can lid might come in at 22". The next factor is how much discrimination you use. On all metal you will get more depth but pick up more trash items. Under ideal circumstances you would never even pick up that trash can lid if you had iron nulled out. Other factors are too many to name but soil condition, moisture of grass and sensitivity settings are all going to count towards depth. If you are looking to find old deep buried coins then this is not the right unit for you. I have two detectors. I use this Bounty hunter for the beach and play grounds where is handles great. For parks and old sites I have a more expensive detector that no Bounty hunter made could match the depth on. With my good detector I have found old dimes at 13". I love the bounty hunter and it paid for itself in a few weeks with a gold ring it found but it has its limitations. The old saying "You get what you pay for". You cannot expect a $100 detector to do what a $2000 detector can do. Lastly, experience and time in the field ( knowing what the heck you are doing ) is key.
