Re: Best GPS Maps for the Columbia River
I have the HDS-7 with Insight USA. It shows the Columbia and Willamette in great detail, including bottom contours, all the marinas, ramps, buoys... pretty-much everything you'd ever need to see. However, I don't think it shows much detail on Oregon lakes.
...Oh yeah, I almost forgot: It show's great detail at Astoria.
