yeah head, yhat bouy info is awsome! dont have to guess where the water is moving or how much. just point and click! eheard a rumor that they will be gettin water temp and salinity data from the bouys soon. that might help track the reds. they love the brackish water. as far as mounting in the car i know my garmin handheld doesnt work very well in the car. but, it doesnt work very well anywhere. maybe within a hundred feet or so. i was a land surveyor for 14 years till katrina hit. when laying out wells (and gettin payed to fish) in venice, la my 337 was always within a few inches of my $30,000 trimble RTK unit. thats perty damn close
