Trolling fin

Great product

Havalina (Mendon, US)
It works!

I now have over fifty hours using the trolling fin in high wind conditions. It works better than expected and when using my kicker in conjunction with my bow mounted trolling motor. I am still fishing at Lake Powell in 20+ mph, when everyone else is bumming around on shore. Now if they could come up with something to get rid of the surf boats.

Works great on the trolling motor to help direct the boat in the wind.

Boat control

WOW!!!!! WOW!!!!!!! what a difference in slow speed control..... We mainly fish Lake Michigan in an 18 ft LUND Fisherman. Slow speed of 1.3 to 3.2 SOG is what we shoot for..We tether the Main motor and the kicker motor so we can steer at the steering wheel...... WOW what a huge difference it is having the trolling fins on both motors.. You can feel there is no more hunting by the trolling motor on auto pilot.....Top end control is right at it too....... Very much exceeded our expectations...... And hey,,,,, Thank you for the fast shipping too.... Thom.
