I was checking out some older posts from last summer, and I see that a number of people were having trouble with the new Excal II. The general opinion was that the new redesigned coil( mainly 10"?) was the cause of so much of the erratic behavior when it hit the water that new purchasers were experiencing. Also some thought it was a misunderstanding of the proper way to set the sensitivity control. I noticed that you(Floridabill) mentioned that you had bought 3 and sent them all back. Can you or anyone tell me if this remains an issue? I have been seriously considering saving up for one, especially after seeing some of the videos of them in action. Thanks a lot for any input that can be provided on the current situation on this product.
