Disc Defender is a lost and found notification service for disc golfers. When your disc is returned to a participating business, we text you — so you can get it back fast.
Write your name and phone number on the inside rim of your disc using a permanent marker. This is standard disc golf practice and is required under PDGA Rule 813.01, which states all discs used in play must be uniquely marked.
By writing your phone number on your disc, you are indicating that you want to be contacted if your disc is ever found and returned.
Tip: Write clearly and legibly — a smudged number means no call!
When a participating business (a disc golf pro shop, course, or retailer) receives a returned disc, they scan or log it into the Disc Defender system.
Disc Defender sends an initial SMS to the phone number written on your disc:
"Disc Defender LLC: Your disc was found! Respond YES to opt-in to text messages and receive more information about your disc. Reply STOP to opt out. Msg & data rates may apply."
No spam. No marketing. Just one message letting you know your disc was found.
Reply YES to confirm you want to receive the disc return details. This is your explicit consent to receive SMS messages from Disc Defender.
Once you opt in, you'll receive:
"You're now opted in for Disc Defender alerts! We'll text you when someone finds your discs. Reply STOP anytime to unsubscribe. Reply HELP for help."
Followed by the return details:
"Disc Defender: Your Discraft Anax disc was returned to Nexus South, 2866 W 47th Ave, KS 66103. Reply HELP for more information."
Head to the listed business to pick up your disc. Done!
