Underwater Treasure Hunting Using Remote Operated Vehicles (ROV)

By Michael Bernzweig

In the news we hear of famous ship wrecks and the heroic stories of their underwater recoveries. Mel Fisher and his crew discovered the Atocha. This ship went down in the year 1622, just off the coast of Key West Florida. The treasures that were located with underwater metal detectors included silver cobs, gold bars, emeralds and other jewelry. Another famous treasure recovery was the discovery of La Capitana Jesus Maria off the coast of Ecuador. The recoveries of gold, silver and other precious jewels from this wreck have been estimated at over 3 Billion Dollars. Advances in technology have enabled divers to unearth discoveries like these by using an entirely new range of underwater search and recovery tools. In this article we will cover remote operated metal detectors, remote operated vehicles (ROV), underwater light systems and underwater camera & video systems. We will discuss the applications for these devices and the points to consider in selecting the best equipment for your expedition.

When diving for treasure, some exploration is best done remotely. Extreme depth and pressure make it more feasible to use unmanned inspection devices to conduct the initial exploration. In this case, a remotely operated vehicle is a great solution. These devices can be operated from the surface and guided at great depths. These under water amphibious vehicles are powered by jet propulsion to thrust the vehicles both forward and reverse as well as vertically and laterally. These units can be equipped with a wide variety of options. Some of the most popular options include manipulator arms, high resolution cameras and color viewing monitors, additional cables and connectors.

Remote Operated Vehicles (ROV):

Once you have guided your remotely operate vehicle to the location of a wreck or object to be located, you will want to attach a remote operated metal detector. These devices are able to sense the location of buried targets and transmit the findings back to the operator. The JW Fishers RMD-1 is a unique metal detector that can be attached and used with the JW Fishers Sea Lion, the JW Fishers Sea Otter and other ROV's. Remote operated metal detectors are commonly used by commercial divers, law enforcement, military, salvage divers and treasure hunters. They are useful in the discovery of ships, anchors, cannons, pipes, cables and other metallic buried objects.

Remote Operated Metal Detectors:

Treasure hunting underwater sites at great depths is not possible without underwater illumination. When selecting your underwater lighting you will need to decide the scope of your needs. You can choose from hand held lighting devices or devices that will illuminate a larger area.

Underwater Light Systems:

Utilizing underwater camera & video equipment will allow you see and properly record and document your findings. These devices come in a variety of formats. For recording and viewing smaller areas you should select a hand held device. If you are scanning larger areas you should consider either a dropped or boat towed camera system. This will allow you to document vast areas with greater ease.

Underwater Camera & Video Systems:

Choosing the best underwater equipment is an important first step to any underwater exploration project. Remotely operated vehicles are an invaluable tool to assist your team in unlocking the mysteries of deep sea exploration.
