Well if you like to only cry once then get both Mega units. As Rickie said the Gen 1 unit has blended di. Once you see the difference you might be sorry you bought the Gen 1 unit. I have been using a Helix 10 si Mega for about 6 weeks now. I was in the missile and radar field for almost 40 years......very familiar with CHIRP technology as is used for target separation. To me having si and di CHIRPed is a huge game changer. I have been able to find shell-crackers just inches off the bottom with the di. With the Helix 10 I can tell you which way the fish are facing........not that it really matters....LOL....but that is just how good these units are. Here are some images......one is of KY bass spread out on bottom and the other is crappie stacked on concrete structure. I look for structure like most......but with the Mega unit if my scan doesn't show fish I move on. Hope this helps shed light on your upcoming purchase.
