Calibrating the Buoyancy
The DTG2 ROV is shipped from the factory calibrated for fresh water use. To adapt for salt water, simply
add the provided ballast plates, as shown in Fig. 4, evenly to the top mounting points or bottom
mounting points. These weights can be added or removed as desired to gain the preferred buoyancy. It
is most common to bias the buoyancy to a neutral or slightly positive setting.
Every body of water will have a different density, generally when changing to salt water, we recommend
adding 4 ballast plates to start. From there, small ballast plates can be added or removed to ensure
neutral buoyancy.
