Tips for using a submersible antenna

The user in the boat should be a specialist or have 
considerable experience using a locator so that they can 
give concise instructions to the diver.

It is prudent for the pair to practice working together on 

dry land before attempting to locate underwater. Using 

the antenna the diver should locate and trace a known 

line blindfolded receiving directions from the user with the 
locator out of sight of the line and the diver.

Because of rapid signal loss and a combination of large 
surface area and very conductive soil there may be 
problems applying a suitable signal for tracing a large 
diameter pipe. It may be necessary to use a high power, 
low frequency tracing signal.

It is necessary to define a method of recording target line 
position and depth before starting work in the boat or on 

the seabed.
