Hi all.
I'm finally decided to upgrade fish finder for my AL 12ft V hull boat from my old 598CI HD SI unit. I fish only on shallow lakes and rivers (up to 50ft). It looks like I will go with Helix 7 or 9 4G. No plans for live or 360 or networking, so I plane to go with whatever model I get a better deal on.
However, I have a few unanswered questions about those units.
1. Are really those units the same resolution, so the difference is only in pixel density? (9 have bigger pixels) Is it any advantage when using it in the console?
2. Mega and Mega+ practical difference. I can't find comparison online, just some demo pictures from HB. Do you guys have any real recorded footage to share?
3. Are those Helix units compatible with maps made in HBTrackMapper_V20a in other words supporting color by depth.
4. 598 will be moved to the bow on the trolling motor. If I somehow manage to DIY that transducer to my Endura 34 modified to bow mount.
I plan to use it only for vertical fishing with 2D sonar.
5. Should I consider some other unit, Helix 8 MSI+, Helix 9 MSI G3, Helix 7 SI, Helix 7 MSI G3, Helix 7 MSI G4N, or even some legacy units from ebay 1198c si maybe ?
6. Something I missed or should consider ?
Thanks for any advice.
