Tranducers
The field-changeable transducers help make the ARC Explorer unique and unequaled in
customization. The system arrives with a single towfish and a pair of transducers, but multiple sets
of transducers are available and allow customization of the towfish, however needed. For example,
one side can be set at 600/1200 kHz and the other at 900/1800 kHz, etc. This system can fit
almost any side-scan sonar need.
