I'm asked questions all the time about 'How to' operate Lowrance units. Most of the questions are ansewered in the manuals. I my self, have to refer to them all the time. If you want to see videos of how to operate them,,, Lowrance has a bunch, to help. Go to www.lowrance.com. Click on support, click on video library, and select your unit. VERY usefull. <*)}}}><
