I have enjoyed using this unit. If you can afford a larger one I would highly reccommend it. Internal map is not the greatest so figure on getting navtronics chip for $149.00 Gps and the trails have gotten me out of trouble more than once already. When hydrilla closed in on entry into an opening off Caddo lake I was able to find where I had entered by using the trail it made. If you know that lake you know how easy it is to get lost (everything looks the same). Still learning to interpret side imaging. Other than wishing I could have afforded a larger size I am very satisfied.
