Thanks for the great advice guys. I am still in the planning stages and have much research and learning to do , here is what i have so far: The wreck i want to dive is the "Golden Gate"which you probably know has already been salvaged, for the most part. I don't plan on finding much of anything, but there aren't many other wrecks in theses waters to choose from.? Any prospects you may want to offer would be appreciated.I am also doing some research on the "Thayer", near Isla Tiburon. I live in Tucson, so, the further north in the Sea of Cortez, the better for me, but i am willing to do some traveling. I am a beginner at the treasure hunting game, but it has always been a dream of mine that will be alot of fun and of course, hard work.There is some information that suggests that there may still be more to find on the Golden Gate and i do realize that most , if not all, of what i find i would have to give up to the authorities but I'm willing to try ...IF.... i could get a reasonable agreement, but then, you know how agreements can go with the Mexican Govt. One minute you could have an agreement , little do you know you made it with the wrong person because they are so unorganized or someone else wants the loot, then the right person catches you and you find yourself in a jail or worse. I know it can be very risky if i'm not careful.? I have been in contact with a local dive shop there in Manzanillo and one of the instructors has told me that i wont need permission if i just want to dive the site with a metal detector or a small dredge but if it were a larger operation, then i would. Now, just like you suggest, this still isn't good enough for me, so i will still go through the proper channels before i get into any trouble. I have been diving in Mexico for many years and know how some things work down there. I have a 50 ft. ketch in San Carlos and my wife is still a Mexican citizen and has some connections,which should help me to find the proper channels to go through. So.. I think it is worth trying to get the permission first and then worry about techniques later. It sounds like that will be a huge hurdle to jump. Thx again
