Marine use: Does this include waypoints for marine use, e.g., channel markers?

Hi Mr. Buchman! I believe this GPS is for use by "landlubbers" only.... While the satellite to GPS link up wouldn't change, the map/voice direction information would be totally useless - no cross reference to marine information (including waypoint). Unfortunately additional software i.e. marine information is not installable by either Tom Tom or the user. You might check with Tom Tom customer service (they will respond to your telephone call - they just will not give you any repair help). Basically the Tom Tom is sold as an "orphan".... Good luck! Jim

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.

I use mine as a backup to the larger Garmin on my boat. For boating however, I purchased the Garmin Blue Chart (North America) on micro sd card format. The waterways and shoreline depicted on the provided topo basemap lacks any reasonable or useful detail for navigation. You can add your own waypoints (i.e. fishing spots, obstacles, etc.) with either mapping system. AA batteries alkaline or rechargeable (it comes with an external charger for rechargeables).

Yes, you must have a list of saved waypoints -and from those can choose to locate any you want. You may also delete all stored waypoints.

I'm not familar with apps for Marine navigation. I can only say that it works very well with foreflight, an aviation app. So I would say that if the app supports that particular GPS through bluetooth, it should work fine.

The transducer does not, gives you temp, depth, and water speed. Your GPS will give you basic heading info when you are moving, but if you need accurate heading data for AIS, radar purposes, etc, then you would need a marine heading sensor - which is a gyroscopic compass that hooks up to the NMEA 2000 network.

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.

Yes you can Store way points and pick from to list to navigate to on the eTrec 20

The usefulness of multi-point routing varies from one person to another. Anyone that has daily routes and schedules, this would obviously be a great help. However, for those units that don't have this feature, there is a way to get by.All Garmin units allow for one "waypoint" to be added. Some people add a waypoint somewhere along their travel route, and once reached, add another waypoint, and so on. Hardly elegant, but this hopscotch method gets the job done.

No, its just the S. Maps separate, although there is a basic worldwide map. You will need a separate Marine map.

It comes preloaded with a marine coastal chart map. But if he is going deeper inland on the waterways he can down load an additional comprehensive Blue Chart g2 with even more detail. He will have to install an Micro SD cart of 16 gig byte to store it on. But it should serve him very well.

No maps, although I only use mine for water navigation. Wait another few weeks, (2015) new models, hopefully better coming out.

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.

Absolutely. There is a free software you can use to transfer way points to the unit as well via USB. I'm currently using it to locate and mark utility manholes.

I've never used that feature, but yes, it does have a compass. As I understand it you create routes and mark points.

Hi. I don't see why you could not. I use mine to mark fossil spots in the badlands, then walk back to them. Because GPS is based on satellite locations, being on water should make no difference. At least that is my opinion. I have not used mine for fishing. Hope this helps!

AFAIK, only the 7x0 series and up have multi-point routing. The other Nuvi units allow for one waypoint to be added. Larry, if the 265wt has multi-point routing, it's the first I've heard about this.Edit: Larry, I just checked with some people on gpsreview.net and they agree with you. This is a undocumented feature. Thanks for your input!
