LOWRANCE HDS GEN2 and above or ELITE TI UNITS ONLY:
Built with the help of Mike Cork and BassmanRudy:
High-Definition Caddo AT5 Aerial Map downloadable link from Google Drive:Caddo Download link
CADDO-AT5map.zip file size is approximately 13GB so you will need a 16GB or 32GB SD-card or MicroSD-card.
A fast read-speed is desirable. A fast-write speed only if you wish to use the card for other functions.
I prefer a Samsung or Sandisk card which Best-Buy stores sell.
CADDO-AT5map.zip contains the 13GB SHADEDRELIEF folder. Just extract or copy the SHADEDRELIEF folder to the SD-card.
By default a Lowrance HDS unit will have ShadedRelief enabled, if not you must enable ShadedRelief viewing.
CADDO-WR&T_xx.zip contains the following Caddo trails you may wish to import into your Lowrance unit:
BIGCYPRESSBAYOU.GPX is the Big Cypress Bayou current path and rerouted paths.
Note: Some sections of the CaddoBoatRow trails and the Bayou trails overlay.
CADDOBOATROW.GPX are the Caddo Boat Row trails.
Note: Some sections of the CaddoBoatRow trails and the Bayou overlay.
WARNING: CADDO IS A SHALLOW, LIMITED VISISBILITY AND DANGEROUS SO ONLY YOU CAN DETERMINE WHERE AND WHEN TO OPERATE YOUR BOAT SAFELY.
WARNING: CADDO BOAT ROWS ARE MARKED BY POLES AND DIRECTION-ARROWS INDICATING THE PATH TO NAVIGATE.
WARNING: SOME CADDO BOAT ROWS HAVE LIMITED VISIBILITY.
WARNING: CADDO BOAT ROWS CAN HAVE UN-CLEARED FALLEN TREES HAZARDS AT ANY TIME.
STATELINE.GPX marks the Texas and Louisiana state-line.
You should edit the Caddo trails after importing to change the trail color as desired. I recommend:
BigCypressBayou -> BLUE
CaddoBoatRow -> RED
StateLine -> WHITE
