I currently own one detector. I have a Tesoro Tejon and use it for relic hunting. My first machine was a Relco Frontiersman and that was about 1971. Have probably owned 25 since then. Tejon is a must have for the deep relics, especially in damp or wet soil. However, I do need a second machine for coin hunting, need something with target ID. Sold my Minelab Exploreer II last year to buy a White's DFX, sold that because did not like it at all. Considering either a Tesoro Cortes or maybe a Minelab Xterra 70 for coin hunting. Saw my first Garrett ACE 250 yesterday and it looked like a toy to me
