See the seams on your GPS ? Wipe clean with dilute dishsoap, rinse and wipe with isopropyl. Cover seams with 3M 33 electrical tape.
Now on the Florida coast after buying West Coast Garmin charts of 6 years ago, I shelled out more for the East Coast.
I'm pleased. The maps are cheaper
Paddling near bottom countours via Garmin's NOAA maps is more fun here in low tideland than on high velocity Haro Strait with sea mounts an variable overfalls. The wee bit of extra velocity here exposes your experience directly onto nature's watercourse.
Big Carlos, east of Sanibel Island, described as a 'lake' is not. BC flows down around water hills, thru choppy channels, and downhill ! As experienced from the kayak and a Garmin charts equipped Csx. Where you may gradually develop a sense of place without Garmin, with Garmin and pretrip laptop planning, you are there right off the ramp.
If you need electronic reality, a pretrip track used for routing on water brings a Csx screen, 2 screens, with several windows of info each screen; eg distance made good, distance to go, time of arrival (or not), time to sundown, time to dinner, average speed when in motion....time to the next Cigarette....
Combining Burch, Garmin, and Google Earth with Goretex and Kevlar/CF....incroyable
Burch deepens your sensitivity to where, how and who you may be as a kayak mariner. A quality the GPS merely alludes.
