I am looking for a 9" plus unit that wont break the bank with side imaging. Prefer to stay under $900. I have been looking at the gen 1 helix 9 which can be had for about $750. Its my understanding that it uses a different transducer than the helix 10 which equals lower picture quality. I cannot find any of the gen 1 helix 10. I have a helix 5 now and I am considering going to another brand for my sonar needs to get the best unit for my budget. I can use my lakemaster on my helix 5 if necessary as I don't want to lose that capability. The hook 2 9 comes in at $800 but I havent read much feedback on that unit yet. Can any one recommend other units? Thanks.
