3D mobile, PC, and ALL waypoint charts are provided as a digital download unless you select “ship me a card.” You will be provided a link to download the chart files after checkout and in your order confirmation email (check your spam folder).  Download the file, double click it, and read the instructions inside.  Make sure to create an account at checkout so you can log back in and access your StrikeLines files at any time.

3D charts for Simrad, Lowrance, B&G, and VesselView are mailed to you on a SD/MicroSD card due to our license agreement with Navico. Please enter a USPS approved shipping address at checkout.

Got a Garmin?  Our waypoint based charts, like the Offshore St Pete chart, work well on Garmin. You’ll get all the waypoints just not the red lines. We also provide you the Google Earth version so you can view the lines on your phone, tablet, or computer.

3D for Garmin? Your best option is to use the mobile version on your phone or tablet. Your position is overlayed on the chart even offshore without cell service, you can create waypoints, navigate, and pull coordinates from the chart to input in your Garmin.  If you buy the tablet from us we’ll even pre-load your charts!
