So this is going to be a long post so sorry for that. I ended up buying a lowrance elite 7 that went on the bow last fall. I bought a hds gen 3 7 for the console with side and down imaging. Then I am running a gen 1 hds 5 on the console for mapping purposes only. I kind of settled on the two 7s because we were going to only have the boat another year or two.
My dad is actually the guy that owns the boat. I’m the guy who uses the electronics all the time. I bet my dad couldn’t even turn a unit on. With that said he lost his job in December and my parents financial situation changed drastically. Therefore he will no longer be upgrading boats at this point. I don’t see myself being happy with those 7s long term so I bought a hds gen 3 9 for the bow and was going to buy a 12 for the console.
I have always been a 2d sonar guy with no down or side imaging. Everybody tells me the hummingbird blows Lowrance side and down imaging out of the water. I think with me being a newbie the better picture might be best. So I’m thinking of going with the helix 9 on the bow and 12 on the console. What is the difference between the gen3 and gen 4? Also with the bow one exactly what do I need as far as transducer for a minnkota Terrova? What is the difference between the 360 mega and just the regular mega? What is the a good used price for a helix 9 and 12? Thanks and sorry for the long post.
