Airmar Transducer for Boats - Portland Marine Electronics

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. Casimiro

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