Helix generation identification

[FSHRMN1010]

How can I tell the model generation of part number Humminbird 410000-1 Helix 12 ? Thanks Jeff S.

If it doesn't have a generation number, it is first generation. That is what that unit is.
Second generation Helix units are G2/G2N
Third generation Helix units are G3/G3N
Forth generation Helix units are G4N

AND the model name is on the serial number bar code sticker on the back of the cabinet, on one of the start-up screens, and on the SYSTEM STATUS view.

Any benefit of using any newer model units for
standard 360 use ?

Third and forth generation Helix units have HW CHIRP as standard for 2D sonar and more power.
