From the GeoKnots website: "We don't call this the Ultimate Lanyard for nothing. We took all the things that geocachers need in a lanyard, and made it even better. You won't have to trust your expensive GPS's, smart phones, cameras, and other electronic gear to a flimsy strap any longer. Each Ultimate Lanyard is proudly made by geocachers, for geocachers from super-strong US-made survival paracord."
Each Ultimate Lanyard system includes:
Fully adjustable length to comfortably fit any geocacher. Two interchangeable, quick-disconnect attachment ends for your GPSr or other equipment for additional flexibility. Safety breakaway feature with sliding hand-tied ranger knots. Built-in emergency whistle on each quick-disconnect attachment. Hardware attachment pack for your electronics dash; a sturdy metal snap hook, two mini quick-disconnect cables, and two mini split rings.
