We purchased have purchased 3 from sponsor Russel Marine, arrived quick. On the lake boat the Ultrex, works great at lake of the ozarks weaving in out around docks shooting, but has the remote steer and spot lock too. On river boat we have the Ulterra, simply because i can deploy from the tiller steer in the back thus far no issues, buddy had one had issues but they were related to not stowing before attempting to put on trailer. foot pedal is in a compartment somewhere... Terrova on another river boat works great but the deployment is a bit tricky for very mature adults.....
