Three out of five of my detectors have meters. I use two of my detectors to find bullets and casings at crime scenes. Bullets these days are made of different alloys of lead, copper, and brass. Having a meter with an ability to assign a particular number or location on a graph, to a specific target by programming the detector with a specific bullet type prior to hunting the site saves a lot of time. I could find the bullets using sound only, but I would have to dig virtually every target above a certain level of discrimination.
I use a Lobo ST for coin shooting as well as gold prospecting, and have found some mighty nice silver with it. The first detector I owned was a Whites 4900 D. I found several silver dollars with that old detector, and sometimes wish I still had it. I agree that meters are not always needed, and that conditions dictate the type of detector to use. I have a Toltec II that is a great cherry picker, especially with the 4" coil. I don't care whether Tesoro built it just to fill a "fad" gap in the market. I like it. It finds treasure, as have all of the detectors I have used over the years. The older I get, the harder it is to stand and squat, stand and squat. With the advances in technology, I don't have to work as hard to get the same number of finds. Since I don't always trust my ability to set up some of these newer models (such as the X70 I recently bought), I double check my targets by using the trowel as the discriminator. It is, after all, the ultimate discrimination tool. If we all had the same likes and dislikes, we would all be using the same machines, eating the same foods, watching the same programs, having the same jobs, etc. Having a choice makes life a little more interesting...
