Re: Garmin GPS 152 will not calculate tides after 01/01/2012
Not familiar with that particular unit. Has it been discontinued. That might be an issue with a lot of units. Did you check with Garmin? I have a Gpsmap 3006, Gpsmap 478 and an Oregon 400c. The dates for purpose of determining tides can be changed for all units. I'll look to see how far in the future the tide function will work.
