Marine Electronics Forum - lake soundings

Okay, maybe not exactly a electronic issue, but you can get noaa charts for free of our coast. Now can I get the same thing of Thurmond (Clark's Hill) lake? Thurmond straddles the GA/SC border and is the largest body of water east of the Mississippi. My HDS has the nautic insight hd card and it has the lake, but I really need to see it on my pc. Thanks

Nothing is free of any value.

You can buy a Navionics card and I believe you can view one map on the PC viewer. Or, if you have an iPad you can buy their app that runs on the iPad and view it there - zooming in/out. Not free, but....

This!!

I just looked up the lake the OP posted, that is a huge and the chart is in HD.

OP get the Navionics premium south card ($150) after purchase you get to download the map program.

Will look into a pc viewer this afternoon. I had always heard that you could not use the card on the pc. I. My HDS it looks great. It is a pain in the ass to try to loom at a large area and compare things though. Thanks for the insight. And it is a huge ass lake. Great open water. Main river channel is 130' deep the whole way. Wonderful for downriggers.

Technically speaking, you can't use the card on the computer. After you register your card, you get the option to download the PC viewer to 5 computers and you get free updates for your computer and SD card for one year. What you see on your computer mapping is that exact thing you will see on your plotter in the boat. The new update on the PC program lets you plot courses on the PC and transfer them to the SD card.

All I can say is TRUST ME, you will not regret using the Navionics programs. BTW: You are looking for "Hot Maps South Gold".

I beg to differ our tax money does pay for something. If you go here http://www.charts.noaa.gov/MCD/Dole.shtml
you can download any/all NOAA ENC charts. Once you have picked the charts you want then you can download OpenCPN (http://opencpn.org/ocpn/download/) which is FREE as well and you can import the NOAA charts into the program to view the charts. The OpenCN program is a full fledged chart plotting software that if you load it on a laptop and have a USB GPS receiver you can easily use it as a dedicated chart plotter. The program takes a little learning but isn't crazy hard to figure out.

Last I knew NOAA has very little to do with inland lakes and that is what the OP is looking for. I'll take a look at what you posted anyway.

At a fast glance I didn't see anything inland related.

X2:thumbsup:

The Navionics chip Hot Maps East for my area is far better than my current Inland Lakes Vision chip. So much better that if anything ever happens to my electronics I will return to Raymarine.

Thanks for the help guys. I have a Lowrance HDS 5. I ordered for my offshore trip a nautic insight 2012 Eastcard. It has all the lakes up to the Mississippi. I called Lowrance and they never got back with me. I finally just went out to my boat and planned my trip on the unit in the boat. Was not as easy ai it could have been, But I got it done. Thanks again.

Thurmond straddles the GA/SC border and is the largest body of water east of the Mississippi.

Except for Lake Erie, Lake Ontario, Lake Superior, Lake Michigan, Lake Huron, and Lake Champlain.

I think I missed a few, also.

Where do you get this stuff? Is that what they teach in the South Carolina schools?

Moosehead Lake is the largest lake completely within one state east of the Mississippi.

The others have 2 or more states and country's.

Ok nitpickers, "Largest manmade freshwater reservoir East of the Mississippi." Quick search turned up the following; Moosehead 118 sq miles. Thurmond lake, 111 sq. miles, max reserve capacity 120 sq miles. Of course the lake is so freaking low its most likely 90 sq miles at this point. Also, the "head" Mississippi river lies below Moosehead lake, so technically Moosehead is North of the Mississippi.

Please explain the "within one state" comment.

Champlain is 2 states VT and NY, 2 countries US and CAN.

The Great Lakes are well........ Look at a map.

I wasn't nit picking, just correcting you.
