After looking around at all the great info I decided to join with a couple questions, I bought a older 14' alum V-Hull boat nothing fancy just something to get me and my 8 year old daughter out on the water. Question is. I have been looking at upgrading the TM and fish finder. I am very impressed with the Terrova with I-Pilot but not sure which one to get and which fish finder would be a good match. I do know I need a 54" shaft, 12V. Not sure what the universal sonor 2 is? Any help would be awesome!!
