With some storms in the forecast I was worried about my fellow camp attenders. It is always possible that lightning could hit your fish finder and you lose all of the waypoints where you have marked your brush piles and other honey holes. That would be terrible!!!!! Out of the kindness of my heart, I will provide a data security service to you to protect this vital information that you have worked so hard to collect. JUST SEND ME ALL OF YOUR GPS COORDNATES! After I personally verify that they are indeed good fishing spots I will save the data to my personal fish finder for back up security. If something happens to your unit, your data is secure in mine. I just want to help out.
