Looking to purchase an Ultrex w/i-pilot Link, currently have Lowrance electronics but will add Humminbird unit in the near future. Will I be able to operate the spot lock with this unit if it is not paired with a hummibird???
Yes....and make i-Pilot trails and save spot locks and way points.
The only thing a bird adds when linked up is more storage space for the trails, waypoints, and locks along with the ability to follow depth contours. Of course, the depth contour following requires lakemaster maps. <<<(I think )
