Trolling Speed Question

[TheLynnAnn]

Just wondering what unit of speed (knots or MPH) everybody refers to on this site and radio on the lake. Thanks to anybody who will reply.

I use MPH

[Fowlpursuit]

It is miles per hour. SOG mean "speed over ground" via boat speedometer or gps..."speed at ball" is the speed taken from the probe down at fishing depth. The difference in these speeds can vary greatly depending on current

What Travis said!

MPH, Knots is too hard to break down on the fly. I had a gps that gave speed in knots and had to have a conversion table to figure it out. SOG is GPS speed over ground, and down speed is from the Fishawk or other type of troll speed indicator.
