Great app for enhancing your fishing experience through low impact technology. I use Fishidy every time Im on the water for navigation as well as cataloging successful locations, conditions and presentations. Its even useful on lesser known waters that dont have contour maps because you can plot "catches" and "spots" on satellite image maps. (This might be my favorite feature.) I also use the fishing hot spots points of interest for help on unfamiliar waters or to take a shot at a new structure on my local lakes. It is important to make sure your gps is working properly on your phone or tablet to get the most out of Fishidy. Overall very good piece of tackle!
