Author apparently uses the Formula Degrees Minutes/60 Seconds/3600. This doesn't seem to work in the deep south. Published GPS coordinates for Fish River Reef in Mobile Bay are 30o19.705%u2019, -87o49.830%u2019 This Project returns 30.5125, -85.95278, 113 miles east of actual reef location. Leave off the minus sign before converting but add it after and the results are somewhat better, but still off by 20 miles west-northwest. Actual decimal coordinates are closer to 30.32725, -87.84222
