Underwater Treasure Search: Money Searching, Teamwork Issues, Mini R.O.V.s, and S.U.R.F.

Money Searching, Teamwork Issues, Mini R.O.V.s, and S.U.R.F.
Treasure-searching can be expensive! One day's searching can cost up to a couple thousand dollars! So funding is a major prob to treasure-searchers... so they need to find things to sell. Gold and silver are the most obvious ways to solve this problem. But they need to find it.
Sonar and magnetic scans are a major way to find stuff, like potential shipwrecks, under the water. But there are sites which may look like a shipwreck, but are only sites that have a ton of rocks! In fact, there's a lot of these sites. And then, to top it off, some of the sites may have boats, but not the one you're searching for! You might not even be able to identify these other boats or the reason they sank, making them one big mystery! This can be extremely frustrating, but the only way to tell each apart is by eliminating the wrong possiblities (sp?), and you do that by diving at each site. This can stretch a crew's patience and wind them up, even the top people.
Speaking of crew-trouble, sometimes you have to hand over your authority to your "second-in-command". This may be because you have to talk with the government owning a certain ship or area with a very good shipwreck and/or potential dig site so you can dig up the stuff hidden underneath... especially when it's both a military ship and a highly valuable ship to both history and monetary value. This can cause a lot of pressure on your ship (or ships) by itself when it happens. Why? Certain proof may be demanded by this certain government, and the team has to do scouting and preperation (sp?) for the dig as well. Since you're busy, you just have to trust the team, so it's important to have a crew you can trust! And they need to be able to handle the situation, so a good crew can be extremely important.
Speaking of big-dig sites, sometimes you have to scout the area where you want to dig. But you need a vehicle that's not as expensive, and can manuver (sp?) more. Now, they're not as complicated and have as many tools (though their systems are still complicated!), but there are smaller R.O.V.s than the usual high-expenses one. They can get around better, and are good for scanning and checking out sites... especially when you don't want to risk the higher-tech R.O.V.
While the missions depends heavily on the R.O.V.s themselves, a lot can depend on one part of a R.O.V.. These machines have a special system called a S.U.R.F. system. This is basically an underwater vacuum. However, it can gently blow away sand as well as do suction and get rid of sediment, so it's very important when looking at objects underwater. If even this part of the system breaks, and your on-board R.O.V. repairman or technician can't fix it... might as well kiss the mission good-bye!
