Navionics on a H'bird Helix G2N

[FurFlyin]

Are they compatible? I've got a Lakemaster card that I use in my console unit while driving and I move it to my bow unit while fishing. I know me very well, and I know what's going to happen. It's going to wind up in the lake....

Weiss Lake isn't mapped on the Lakemaster card. Not a detailed map anyway, but it's supposed to be on the Navionics card.

Thought about getting a Navionics card to use in one unit and use the Lakemaster in the other.

If the units are networked, will that cause a problem, or is the Navionics card even compatible with the Helix units?

Before you drop it into the lake - send it to me -- newer chips will not work in my old HB and it will not record waypoints without one

Both cards work on the older units. Some had a slot for both cards and you could switch left or right and use either one. Not
sure on the new units. I know most only have one slot for a mini card. I updated a 788 last year and it took away that option.
I had to take the Lake Master out to get it to read the Navionics card.

Here is a guide for Navionics card comparable units. I use Navionics on my Helix Mega 9 but also have 4-5 lakes downloaded on,single cards of Lakemaster in Indiana as most our resivours and a couple of large lakes aren’t available on Lakemaster and why? I have no idea as Lakemaster as 50 acre lakes on theirs and several in Indiana not on their card.

Thanks for the info. Where did you download the individual lakes?

[cevans]

Hummingbird chart select for single lake downloads. For each lake, you need a single card to install it on. So for example, 4 lakes downloaded you would need 4 cards. https://www.humminbird.com/learn/mapping/chartselect. I bought a bunch of 8 mg cards of amazon for really dirt cheap or eBay even and also use them as well in my trail cams.

Thanks. I had no idea they offered that.

I ordered another Lakemaster card. I think it's a newer update from the one I have. Now I won't lose $120 in the bottom of the lake.
