A unique website dedicated to fishing information from Florida's Northern Big Bend. This includes the area from the Econfina River west to the Apalachicola River
Go to gpsdiscount.com or gpscity.com and get their best price, print it out and take it to West Marine and they will price match it. That is what I did with our 240 Blue and my GPSMAP 76s.
Gps city has the 182 with external antenna for 639.00 and garmin is offering a 100 rebate when you trade in an old GPS or loran (any make). That's a pretty good deal.
