SmartStrike

[duffer0528]

I'm getting Helix 7 SI G3N on console and Helix 7 DI G3N on bow.  I'm going to get SmartStrike mapping card, which i understand is Lakemaster plus the ability to identify fishing locations through some crazy algorithms.  My question concerns the high definition maps vs non high def maps.  The lake we fish a lot (Lake Fort Smith in AR, Crawford county) is non high def.  So, 

1)  Does the SmartStrike stuff not work on Non High Def lakes?

2)  Does the Non High Def lakes still have contours?  If so, at what intervals?

 

PS we also fish Bull Shoals and others that are high def of so still gonna get it...

 

Thanks!
