I've not used the Terrova, but I like the foot control pedal on my Powerdrive
V2. Push left, go left, push right, go right. Everything is right there so all I have to do is put weight on one side of the foot or the other to control my turns while keeping my foot on the "go button". I always had a sore leg with my old style foot control on my old tm. Also, you can get the fully remote pedal with no cord or the one with the like 20 foot long cord like I have and use the tm from anywhere in the boat. The deployment could be a little easier, but once you've done it a few times it's not bad. Still wish it had a rope though.
