Good tip!I have ran the striker 4 for the last year and i highly recommend it to anyone. I would be sure to keep the plugs coated in dielectric grease, my power plug got slightly corroded and it was enough to somehow erase all of my waypoints and reset the unit. when my transducer plug got corroded it caused false depth and sonar readings (1.8 feet). I wish garmin would incorporate screw in terminals on these units.
