If the batteries are charged and in good condition, the terrova will react as fast as the fortex and with better control. I would not own a troller without the I-pilot feature. It takes practice to learn the foot pedal, but the Terrova is much better. The fortex will not have autopilot, ipilot or ilink capability. One of these is a must for multi-pole crappie fishing. You can set it to slowly move down a bank or ledge at the speed you want for bass fishing also. You should be on water with an experienced Terrova operator before passing it up. When I fished Crappie USA and Crappiemasters 8 out of 10 boats were using Minn Kota electric steer motors.
