Hey guys wanted to get your opinion on Humminbird SI units I'm looking into. Can get a Helix 12 Mega SI chirp G2 for same or less than a Helix 10 Mega SI chirp G3. Was wondering if you'd do a bigger screen or better detail? I'll be using it for my front unit to find brushpiles and look at SI while long line trolling. Looks like G3 is a little better imaging but was wondering if you have a bigger screen would help with old eyes.
I'd be interlinking the two if compatible. Thanks for your input.
