If your a GPS and/or charplotter or user, this might be a good time to
become familiar with Ben Ellison's
www.PANBO.com marine electronics
web site.
Some recent news that is sure to shock charplotter and GPS users seems
to be developing now. Go check it out before you next attempt to
trust your chartplotter in a tight situation or in the dark ...
I highly recommend this web-site for reviews and commentary on various
marine electronics products.
