Thanks. I see now where the site has the Onix listed as legacy. I will get a Helix 10 with mega SI and mega DI combo for my console. I can only afford one right now. In a few months, I can get one for up front. Do they make any kind of spotlight transducer for the Helix gen2? If so, can I still use the Helix gen 2 gps unit and connect that transducer?Thanks, this is great info.As for lakemaster. The 2 lakes I fish most are not on Lakemaster. So to get accurate maps, wont I need the Navionics? Will I need 2 cards when I have 2 Helix units? Lakemaster or NavionicsSent from my VS990 using Tapatalk
