WarrenMn- Could you recommend any mapping program to use with my 997S. I would like to be able to move points to a map and make changes. Couple lakes I am fishing & taking pict are not really in navatronis hotmaps but maybe I could use 997 to take a pict of the blank map showing on screen. Was going to post on side finder site but seeing your post thought I should ask a expert. Thanks. Was told that the Humminbird computer program is of little/no help what do U think thanks again.
