Hello again cion2. The last post of mine on the water hunting forum was with my Goldquest Aquasearch. The unit is $1500 and the deal is you get 1. They are limited production and hand built by Eric Foster. In my opinion it is the most sensitive, deepest, surf PI available. The Mark II is a great unit and a good choice, but as Craig PI said on the water forum, it does read waves as they pass over. I overcame this, by simply letting the wave pass by and continued scanning. I would not recommend that you hip mount anything in the surf though. Mount the control housing to the stem and run it. The Mark II will need to have the underside of the coil coated with Loctite Aquamarine Epoxy, if you hope to have it last. It will wear through and begin to false if you do not keep the coating on it. Do you have a dealer in mind for the Garrett or Whites unit? I know of some good ones. The Aquasearch is pretty quiet for a PI. I don't know how the PI Pro works, but I know that there is a LOT of loot found by those who use them. Where are you located? You might want to ask the locals at the next club meeting and see what works and why. If there is anything else I can help you with let me know cion. GH
