A couple of questions I constantly see on Facebook fishing groups and on BBC as well are "Is Solix worth the extra dollars over Helix?" and "What are the difference between Solix and Helix?".
I have put together a list of differences but would like some of the other Solix users to chime in on anything I may have missed or anything I might have wrong.
Here is what I have put together so far:
Solix vs Helix Advantages:
1) Touch Screen!
2) Ability to share map cards among networked units. No need to buy a Lakemaster or Navionics card for each unit.
3) Ability to separately define GPS and Heading if you have a Heading Puck. On Helix, these are defined together so you couldn't get GPS from the internal GPS and Heading from the Puck.
4) Nav Data is totally shared and saved locally on each networked unit vs just "seeing" the data on each of the networked units. Many Helix users have lost Waypoints due to not understanding this nuance.
5) Ability to scroll backwards through SI and DI history and even mark waypoints on areas that had already disappeared from the screen.
6) No dongle required for Ethernet cables.
7) Ability to define custom views with 1, 2, 3, or 4 sections...put things where you want them rather than having to live with the few views Humminbird provides on the Helix.
8) Ability to individually turn on/off 2D, DI, SI, and Mega 360 beams rather than all or nothing.
Other than lower cost and slightly less power consumption (varies by model and size), the only real operational advantage Helix has over Solix is the ability to define a custom screen split percentage on side by side views. As of the 4.020 Solix software release, you now now have the ability to have a 30/70 split as well as the standard 50/50 split on side by side custom views... A definite improvement but still not as flexible as Helix.
