I have a Vibra Pro 560, and it works great. It's good for deep narrow holes and very tough! I hunt in very wet muddy places on the coast of South Carolina and mine takes a beating. You will have to get use to it NOT having a power switch (it turns itself off), this took me some time. I had a gold detector I used on the beach for awhile, and had to keep one in time out while I used the other Never had any other isses with it.
Go with the Vibraprobe 560. It is water resistant (although the manufacturer says waterproff I don't go that far) and a great choice for wet areas.
You won't be dissapointed.
