Lake chip for HDS unit, fishing mostly oahe and sharpe in SD

[jpallen]

What is the best lake chip out there for a HDS-8 unit for Oahe and Sharpe? I do 99% of my fishing here. Thanks

I have no idea on Oahe, but on Sharpe, I dont see how you could beat the Navionics.

Newer Lakemaasters will not work in your HDS. Youll have to find an older version somewhere.

I would recommend Navionics

Yep. For Sharpe and Oahe the Navionics will serve you well.

Lowrance has new insight HD chips out this year. The pro version is available now but the other one comes out in may. The difference between the two is shaded relief and about 50 bucks. I haven't used it but thought I would throw that out to check out because they have 650 lakes in HD and it isn't by state like lakemaster so fishing multiple states should be cheaper without having to buy a pile of chips.

Any chip for Sharpe is not going to be accurate after last years flood. It has changed about 60-70% of the lake.

With that being said, I see Navionics offers the Freshest Data program where you can update your chip for free up to a year, if it is new chip. Sounds like the way to go, after they upgrade cartography you can download that info to your current chip.
