Lowrance electronic LMS-480M General, Current drain, Back-up memory, Sonar, LMS-480DF 50/200 kHz

Now, if you're into the fine details, glance over the next segment on specifications to see just how much sonar and GPS power your unit con- tains. It's important to us (and our power users), but, if you don't care how many watts of power the unit has, or how many waypoints LMS-480 can store, skip ahead to important information on how LMS-480 sonar works, on page 5. (Background on GPS begins on page 6.)
