We currently own an ulterra and a ultrex. In our jet which is a tiller steer the ulterra self deploy is swell, the foot pedal is in one of the storage boxes, never been hooked up. In our old 87 champion bass boat the ultex works wonders, as Rickie mentioned above it is very similar to a cable steer. They both are excellent. The ulterra is nice if i am taking kids or those not familar as I can stay at the back by the tiller steer big motor and run the boat. I can tell you that around lots of timber or docks I prefer the Ultrex and more responsive steering. Probably too old to learn the flat steering kept going in circles. That said I think you can still get a Terrova in 12 volt, My favorite is the Ultrex but love the ulterra and the Terrova was good.
