What are the main differences in say a 999 si/di and the new helix, I am going to up grade to birds, wanting to compare the two ,
Thanks
The helix is faster and brighter.

I just bought a helix 10 si di and it's by far a better unit that my 898 di si .You can see it with your polarized sun glasses in sun and it is a lot clearer screen on the helix model
