Sam Rayburn Boat Lanes

These are removable micro SD cards and SD card adapters that contain fishing hotspots. Each fishfinder comes with micro SD or full size SD card slot to install waypoints, retrieve screenshots, update software, or install upgraded contour maps. 

These SD cards are mainly filled with fishing hotspots and creek channels to help you narrow down where the fish are quicker to help you run a pattern of how to catch fish all over the lake. 

These are designed to give the newer anglers, weekend warriors, or traveling tournament fisherman the best odds at doing well when they can't spend all of their time idling around and looking for structure. Take the hard work of guides to be able to narrow down where high percentage spots and populations of fish are to make your days on the water more enjoyable.

Definitely! If you purchase a silver or gold level SD card and want to upgrade it, send us an email with your name, order number, or contact email at sales@fishingmapcards.com. Let us know which product you'd like to upgrade to and we can send a new invoice for the cost of the difference!

We travel to these lakes and put the time in to idle the lake and graph high percentage spots. Using guide and professional tournament knowledge along with time on the body of water, these fishing hotspot maps are created where we actually fish on the water. 

The creek channel maps are created using aerial imagery to trace creek channels and find pond dams and then are confirmed on the water.

Garmin uses a different format for their tracks and trails that does not work with our software. Tracks like creek channels that we mark are a combination of 100's of smaller tracks combined into one. Garmin won't show these trails correctly which reflects some products having a less expensive cost for Garmin products or not even having Garmin as an option.
