Airmar Transducer for Boats - Portland Marine Electronics

[@ksi40]

Long ago I acquired an Airmar p66. However I'm not sure you install it, because I don't know if the transducer has kickup Protection.
Would you be so kind to confirm this.
Many tks in advance.

Hi. What do you need to make a TM275LHW into a water speed built in as the thru-hull transducers? Thx
