Helix 10SI vs. Helix 9si

[Ejmurd]

Are there any differences between these two besides 1" screen size difference?

[Tim Kelly]

No, but they both use the same size case, it's just the display area that's smaller in the 9.

[Wayne P.]

Yes, there are more differences.

The Helix 10 has a higher resolution display as well as 1" more diagonal measured display. It has about 3,000 more pixels per square inch.

The Helix 10 SI GPS comes with the XHS 9 HDSI 180 T transducer.

The Helix 9 SI GPS comes with the XNT 9 SI 180 T transducer. Most that want shaper images, exchange that transducer for the one that comes with the Helix 10 SI GPS.
