trolling bag question?

[Eyezcrazy]

The bigger bags are going slower in colder water. I start out trolling around 1.0 knots in April when the water is very cold. Based on my bag combination I can control my speed by a 10th of a knot. A 10th of a knot is the difference between catching fish and not catching.

Skipper, what are you using that gives you such an accurate reading? Heck my gps bounces 3 tenths all the time.

My lowrance HDS 10 with external gps antenna is very accurate. It still will move up and down a little but i just take the average speed.
