I was looking at my Texas Saltwater Fishing Magazine & Texas Fish and Game Magazine tide charts comparing them. Both claim to use the Galveston channel station.
On June 1, 2008 for example the TSFM shows a high tide at 4:32am and a low at 8:53 pm.
On the same day, TFGM shows a high at 4:25am, low at 9:30 am, high at 11:56am and a low at 8:50pm.
On June 8, 2008 it shows the same type of discrepancy... 2 tides on the TSFM and 4 on the TFGM along with different times. The times aren't much different but I am just curious why they could have differences period. Both magazines show the EXACT same tidal correction numbers up and down the coast.
What prompted this is this question?
Since tides can be "predicted/forecasted" in advance along with tidal corrections based on minutes of correction for lateral distance from the base station does anybody have a good answer as to why Garmin, Lowrance etc. doesn't just program these correction factors into their software and give you the tide based on your actual GPS location?
I called Garmin and the technical guy that I spoke with didn't have any answers and said he would bring it up in their next meeting... He was friendly and helpful but basically sounded like "tides" weren't that big of an issue. I told him to go check with the guys from the FLW tour to see if they feel like tides aren't that big of an issue for saltwater coastal fishing.
