Hi,
I just bought a boat (demo) that come rigged with a Helix 7 DI GPS.
As I do a lot of fairly high speed (4-5 mph) trolling in shallow (2-6 ft.) rocky areas, map accuracy is really important (I use the Navionics + with SonarCharts) and, after viewing some videos, I thought Autochart or, better yet, Autochart Live were pretty awesome features.
However, it seems that the Helix 7, even if it support Autochart (regular, with the Zero Line card), doesn't have the capability to record the sonar data AND read the Navionics card at the same time, having only one card slot...Is this right? Or does it have an internal memory?
Now I'm almost considering upgrading to a Helix 9 Sonar GPS (without the DI or SI, as I don't use it)...Any better ideas?
Thanks.
