It's overall a pretty good machine. I've owned one for some time now and have never encountered any significant downsides or problems with it. It gets pretty decent depth, works good in and amongst iron, it's rugged, waterproof, and is overall a simple machine.

However, it performs terribly on the beach, I don't mind this because I don't think there is much to be found on beaches anyways. I do have some issues with electronic interference and highly mineralized soil as well.
