Recently got an HDS5 original to put on the TM and am looking at getting an 8 or 10 to put on the console. Iv done some looking online at the new features the GEN2 has but its kinda a blur to me. Can someone help me understand the differences in the old HDS models and the GEN2 models? What is the StructureMap view and what would the primary uses for it be? From what I have seen, its approximately $200 more for an HDS10 original than it is for an HDS8 GEN2. Are the features the HDS8 GEN2 offers better enough than the original HDS10 that I should drop screen sizes to get the GEN2?

I primarily fish for crappie in the warmer months and catfish in the cooler months if that makes any difference. Might also look into getting into some hybrid fishing in the future.

Thanks in advance
