Hey guys. Need help deciding on a new gps/sonar unit. I have been researching the lowrance hds 5 inland lakes and have a buddy who loves it. Is this the route I should go or does anyone else have any suggestions. I also looked at the Lowrance elite 5 dsi/gps. Would love to have dsi but noticed the price was cheaper than the hds 5. I figured anything with dsi would be much more expensive than just your normal sonar unit. Is there something I am missing here?
