Great Replacement for Garmin

I've used the Garmin Bluewater chart plotter for a couple years now... Until they discontinued it!! A replacement was needed, so tried several, (which cost a small fortune). Sea Pilot won out after some trials. I'm still learning all it does, but oh my, it will easily replace Garmin. It has more features, like AIS boat identification, easy distance measurement, ETA to all waypoints, easy plotting and Editing etc.
The charts are very good, same as Garmin. Unfortunately, it does not have Active Captain. For now, I'll have to keep Garmin just for access to that.
I am giving Sea Pilot 4 stars because I haven't used it under sailing conditions yet. After that, in a week or 2, I am fairly sure I'll be upping the rating to 5 stars.

Great App

This APP is really cool...received as a promotional gift at the Miami Boat Show. Downloaded the APP to my I phone and used it right away over on the gulf great and you can set it up to show what you want to see or not. I feel this is a great way to backup your chart plotter just in case...

This app looks pretty decent until you find out that it cost $40 to access the AIS Internet data.

They are other apps, maybe not as sophisticated, but are free.

Developer Response ,

The price 40USD for Premium includes all extra functionality like weather routing, auto routing, route planning, weather forecast, NMEA integration, multiple use of five devices, etc, etc and also internet AIS.
