"Anyone want to offer a value comparison between the GPS-12 at about $145 and the GPS-48 at about $210? " ** The thing about using a gps while kayaking, is that it is very difficult to read the lcd, but you can view it from inside the cockpit for reduced glare. The Garmin 48 doesn't exactly have built-in charts as one programmed and built to interface with CMap cartridges or the GMaps. I tested a 48 and a 12 while sailing, liked them both (both a 12-channel reciever), but would get the 48. I like the idea that I can take it on an expedition, get the 30' antenna extension cable, and in remote areas, toss that antenna up into the trees for improved reception in such areas as fjords, mountainous/glacier-ous regions, whatever. The water resistant issue: I have a Cell Safe which fits my hand held gps perfectly: it's like a mini pelican box but cylindrical, foam lining and all- and I reviewed and tested it for sea kayaker, finding it to be pretty bombproof, and you can secure the container to anywhere on your boat. The marine database is helpful yet not completely accurate: as it is not updated unless you do so via a coast guard/noaa site, although I think Garmin has some type of service for this, and I know Maptech used to, for the data anyway. To me, it seems like the database is partially worth it, but the removable antenna and other cables and abilities are well worth it. For instance, I do trip planning with (used to w/ chartplotter and cmaps on a fishing vessel) navigation software, electronic charts and the 48 has the ability to interface with this type of system. I still use my charts and unmechanized navigational techniques, but this method is terribly efficient, doing calculations and adding them to a printable database, which I can figure on the charts(all waypoints before hand) and upload to the gps via serial port and data cable, or if data is taken while underway, I can download after and save that trip record for future reference. Good luck, always worth a call to the manufacturer or checking specs on their site. Depending on your paddling plans and style, ( many islands, much fog, expeditions, guiding...)a gps can be a great asset.
