Fish hawk speed question

[000]

I use a handheld Fish hawk to give me temperatures, however I don't have a speed transmitter.

 

Do you guy's normally see a typical speed correlation between speed at the probe and your surface (GPS) speed? In other words, if your probe is reading 2.5 mph, your surface speed is usually 3 mph, or is there no real relationship? 

 

Thank in advance for any information or observations you can share.

Not always a relationship due to the strong currents from the river. Especially the west end of lake. Sometimes it’s not as bad off shore. Down speed in my opinion is very important. You can learn to watch your rigger cable and diver rods for more of an angle of the cable and bow of the rod.

There’s no correlation due to subsurface currents. Some days your doing 1-2 mph more or less on the surface compared to down below.
