You mentioned items used by treasure hunters and it made me think of a potential need they may have, and a (small) need in the public safety diving community.
We often use Side Scan SONAR systems <www.MarineSonic.com> and have a need for an underwater datum that reflects a SONAR signal well and has a shape that is unusual enough to stand out from "normal" bottom features. Right now I use a collapsible steel dog kennel. One problem is that the mesh of the steel is not spaced close enough to give a strong SONAR return and there are not enough sharp angles to reflect the signal well. Add to that the fact that it is steel and begins to rust after a period of time. Some folks use wire mesh boxes (like crab traps) but those don't collapse well.
I am not certain how many units you would sell but I think I have some clients that would be interested if the price was reasonable.
