Thread: Second Helix setup?

Looking for the Second Helix unit. I have the 10 SI on the back now. And have been moving it forward to use when fishing up front. Sure is a pain to mark spots. Then unhook unit move to front hook up, then got to way points. Now only looking for DI on this unit. Along with hooking it up to the rear unit. Where way points are shared.
Looking at the 9 or 10, like the 10 better as it has more detail. But does cost more, so may go with the 9DI. If I could share way points on the Helix 7 unit. It would work, but looks like its out on that. So back to the others, even thought about buying the 12 chirp on sale for almost what I paid for the 10SI back in the spring.

Now what can be shared between the helix 9,10 or 12 units? I know I'm over looking it. But for the life of me have not found it. Also can I just buy a cable and tie both of them together? Looks like when I go with the 360 I will have to buy the $250. box then as its three items sharing info.

Before I forget, front unit most time's will be used to fish structure right under the boat. So detail counts for sure. Its nice to watch your bait or baits. While watching each fish hit or do a drive by on your bait.

P.S. Forgot to ask this question.. Would it just be better off going with a new 1159 DI or what ever model there called? I can get a new 1159 DI with TM transducer for $699. Only issue I see is being they dropped these models from the lineup. If a couple of years. There going to stop updates and stuff same as they did the unit I have up front now. But I did not know they had dropped that unit. Until I had bought it.
