Does the 78sc include the Great Lakes coastal areas
1431787
Hi Thomas,Since I just have the 78 I'm not sure. With the 78 I bought the micro card that gives me maps of all US, Canada, some Bahamas and Mexico. The original GPS without the card gave only a no detail sketch of landmasses. with the card, it does show depths and boys of the great lakes areas. According to the west marine catalogue, the SC comes with the chart I bought preloaded, which is a really good deal. Had I realized I would be buying the chip, it would have made more sense to get the SC. I'm thinking about adding the chip with topographic features for land travel. http://www.westmarine.com/buy/garmin--gpsmap-78sc-marine-handheld-gps-receiver-with-compass-and-barometer--11553609 Hi Thomas,Since I just have the 78 I'm not sure.

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. You have to buy the appropriate chart set. The 78SC comes with a Worldwide Basemap but this is not satisfactory for precision navigation.

The supplied chart of the World is seriously out of date and very limited.You would need to purchase a marine chart for your area.

Can't confirm for sure but Magellan site states it includes map of North America which I believe normally includes Canada.

I haven't done any travel in Canada, but I know that mine has the eastern, Midwest, western U.S., and Canada maps loaded in the system. I had no problems traveling from Ohio to California... So my guess would be that the Canada maps would be accurate as well.

This is per the Lowrance site:The Navionics Gold Bundle cards include Navionics Gold data for Coastal US and Coastal Canada. These areas are all included on one custom card that Navionics makes specifically for us and only work in our Mark and Elite mapping units. A standard Navionics gold card can be purchased by region from a Navionics dealer in one of several regions.

The detail is quite amazing! I checked out Lake Huron. The tighter you zoom, the more detail you get. Markers, channels, depths charted down to 1 foot! It even goes inland in some places. I followed it all the way in to Ojibway Island, Saginaw, MI.

Yes, it has maps of US Lakes. There are other more detailed maps available which provide more detail.

When you say charts do you mean depth charts of various lakes? If so it does not come loaded with that info.

The tide and current info are part of the "Blue" charts. The 78sc comes with charts for the US and Bahamas. You can buy the charts for the 78 or 78s, either on micro SD cards or to load on your own micro SD card.

Yes, it is. Please see item #4 on the Great Lakes FAQ page at http://www.greatlakesgelatin.com/consumer/FAQs.php

Some points of interest / cable crossings are available on the card. Most reef coordinates can be found county by county online, I just copied into a spreadsheet then converted to gpx files and imported.

I had bought the GPSMAP 78, NOT the SC. The regular 78 has sun and moon rise and set as well as best times for fishing, but if it has the tide info, I sure can't find it. I am fairly sure that it does not have tide info, and as I said in my review, the downloadable "manual" is a joke. as other people said, they hit find and scroll down to tides, but when you hit enter, all you get is a line that says navigating to the tide station, but no tide data is displayed. and the manual doesn't even address the issue at all. I am very disappointed.

yes, if you go through the detailed pics and you can see there is a section that covers the port area.

It does not include marine charts. I purchased them seperately to see approximate depths. It does include inland waterway markers with their ID's.

I don't believe it does. I use it on the Great Lakes where tides are not an issue.

I'm not sure what you mean by coastal charts. When I fire up my unit and it connects to the satellites it gives me an image of my lake from which I could navigate. For more detail and contour lines, I can by a Lake Master chip for about $100. Hope that helps.
