Your best bet is to jump over to the DetectorPro forum. You will find people there that will be of great assistance to you. Bugar uses the Landpro and I'm sure he can give you plenty of tips.
I personally use the HH Wader and just love this machine. Most people don't know it but Gary who owns DetectorPro was the inventor of the Minelab machines (excals included). He then sold that company and started this one. That alone should give you some idea how good these machines are.
I take my Wader to the beach (ocean) and work the dry and wet sand and even go into the surf. When detecting fresh water I can discriminate out the junk metal that I don't want. It's also great when your detecting a park or playground and it looks like rain. Let it rain, less people to bother you that way.
No need to leave because the entire unit is water proof to 6 feet. Six feet doesn't sound too deep, but if you were in a pool that was 12 feet deep and you were 6 feet tall, you'd need to stand on the bottom of the pool to max out the depth of these phones. I just like the security of not having to worry about anything getting wet as it's all protected.
If a rouge wave knocks off the headphones and they hit the water, or I get splashed by some playful people, no problem, pick 'em up, put 'em on, and continue hunting. There's no worrying about my electronics getting messed up.
This is a great all around detector for the money. It's light weight and easy to use. You can detect for hours without any arm fatigue.
I wouldn't hesitate to purchase any other detector from this company. The service is outstanding with quick turn around time. You can call them and speak to any knowledgeable person including Gary and get answers to any of your questions.
To me the best part is that this is an American made product by an American owned company.
