Hey guys. I just joined the forum and this is my first post. I currently have an elite 7hdi on the bow and an elite 5hdi at the console. I have all the GPS and sonar I need right now but would like to add side imaging at the console. I've read a little bit about using the helix 5si and that people are swapping out for the better transducer. What would you guys do in my position? should I sell the elite 5 and go for a decent humminbird unit? I would like to keep it under 500. Thanks in advance.
