GPS Chart Plotter Sonar. HELP

[Priority1]

Frank, have you made the connection to run your laptop off of boat power yet? I was told by a manager at Radio Shack that I could not do that because the 12VDC pulses?? He also said the laptop power connection is proprietary and that I'd have to buy the connector from the manufacturer?

I guess I some how missed this post. I do get busy in the Summer time. I have a 12V DC charger that plugs into a cigarette lighter outlet. When all laptops are plugged in be it in the car, boat or home they are brighter and of course the battery gets charged. I bought the DC charger on ebay for under $20.

I did make some changes in the settings that keeps the toughbook on all the time.

After using the Laptop GPS Chartplotter for a full season I have no regrets for going this way. I have a 13.3 inch screen that even I can see from the back of the boat.There are pros and cons to everything. A lot of marinas and campgrounds have WiFi and I can make phone calls or post a report here with it. It's not for everyone but it works for me.
