I have been using the 8"Excelerator on my MXT for a couple of weeks now and I am impressed. One thing that I have noticed is my coins on edge finds have increased. I definatly get a better on edge signal than with the stock coil. Also the 8" is vsery stable. Can run wide open. The soil I am hunting in is averaging about 83 and the excelerator works like a charm. Just thought I would post my 2cents for what it is worth. I now have the 5",8",& 12" excelerator and feel like I can handle just about any situation.
