Does this version show intercoastal dredged channels ?

I really don't know about the IC channels, but no matter what you buy remember that the storms of this past year have run ragged w/ the coastlines. I live in FT Myers Be Fl and our flats are all moved around, channels are moved, and I know the same is in the Keys. Consult a local boat person for accurate advice. Fish on!

Yes, but only navigation up dates. Not really a big update. No sonar or community edits. If i had it to do over I would buy the Navionics +, you pick the area you need and it comes with full updates, sonar and community.

You have to buy the appropriate chart set. The 78SC comes with a Worldwide Basemap but this is not satisfactory for precision navigation. I bought the Garmin Lakes & Rivers chart set for the US. This includes even really minor streams, lakes and rivers. This chart set includes data where rivers (inlets) meet the gulf or other coastal water. If you plan to navigate one of the coastal areas away from inlets, then you need to buy one of the blue water chart sets. You can download a purchased set (but have to physically install a memory card purchased from one of your local vendors) or buy a memory card from Garmin with the chart set already loaded. The download is faster if you are in a hurry.

Sorry I am unsure, it does however show a picture of where the ports are, si maybe check the photos section and with all the colors because some have more photos then others.

It's the 547xs. It refreshes often. I used it on my 22' in the Chesapeake Bay last year and it was great.

Yes. You have the option of displaying several data overlays, including water temperature, depth, position and SOG. You can also choose the font size for each of the overlays. I've only had the unit for a few weeks...so I am still behind the learning curve. However, the overlays were easy to set up.

/no the top of the line is the 1198. The 998's made before this year are NOT HD, but the HD really refers to the screen not to the depth/fish finding function. I recently had to send mine back for service - very quick turnaround but have not been able to put it on the boat yet to check if everything was fixed. If you are fishing saltwater consider that Lowrance offers Broadband radar - much safer and more close-in detail than regular radar - which is offered by Humminbird. If not dealing with radar its a tossup in my opinion. Good Fishing !!

Yes Just click on the FIND button and you'll see a bunch of icons with Recent Finds highlighted. Scroll down to find TIDES and CURRENTS toward the bottom. I never use Tides, instead preferring Currents. When you are active with the GPS in coastal waters (or if you have saved a waypoint) there are strategically located Current locations marked with a light rose-colored Diamond with a G in the middle. Place the pointer over this icon and hit enter.

I dont know about coastal charts but mine has inland lake maps. The maps that are on the unit do not have any detail. I ended up getting the navionics map card.

I don't know. I sent it back because the shortwave channels didn't work well for me here in Phoenix.

I can't say if the maps are current when you receive the receiver, however, it does come with free lifetime map updates.

No any model in Lowrance's line that has the X on the end of the model is just a fishfinder. They have the Lowrance elite-4 dsi combo which is both gps and fishfinder. But you will need to purchase a navionics chart for detailed mapping

I don't recall one and don't remember using it for that purpose. I left the unit in my boat over a hundred miles away and I am unable to check it out at the moment. Sorry.

No. You have to move it around to see if you can get other channels. And rescan each time

Yes, it has a QAM tuner for unscrambled cable channels, as described in FAQ #5 and subsequent duscussion here (copy link text and paste in your browser's address window):http://www.avsforum.com/t/940657/magnavox-537-535-533-515-513-2160a-2160-2080-philips-3576-3575/120#post_12470932

Yes. I connect my 720 to my laptop and via the internet the maps update. Even construction warnings are updated.

Yes, it is. It is called a "dual triode" tube, so both signals pass through the tube. I love my ocean, hope you will too.
