I currently use a V machine which is my first Tesoro. I am quite please with the performance, especially the fast retune. Having thoughts of picking up a Eldorado Umax. What differences or advantages would I see with the E compared to the V, besides not having the HOT technology. I hunt coins in parks and old homesteads, relics at 1800s plantations, gulf of mex. beaches. The ground here is very low mineralization
