“The ultimate protection against musical instrument theft.”

What is it?

JOYKEEPER is an anti-theft device specifically designed for musical instruments. It can be quickly and easily installed into most musical instruments, without damaging the instrument. Leveraging a cutting-edge network called Helium, JOYKEEPER is more reliable and efficient than traditional GPS or cellular-based asset tracking solutions and requires little maintenance and no monthly fees.

How does it work?

JOYKEEPER uses a new kind of networking technology called “LongFi” (powered by Helium) that has 200x the range of traditional WiFi with 50x the battery life of cellular modems. This allows for JOYKEEPER to last for a few years before needing to be recharged. If your instrument becomes lost, JOYKEEPER geo-location capabilities can be used to determine its location.


As a professional touring musician, founder Mark Sean has a keen understanding of musicians’ needs. The device can be custom installed to fit the instrument in most cases, whether you wish to protect an acoustic guitar, electric guitar, guitar amp, or even a drum kit.

Key Points

  • Protect your investment — know the precise location of your musical instrument at all times.
  • Powered by Helium’s LongFi network, there are no monthly fees to maintain service.
  • “Set it and forget it” – because LongFi technology is low-power by design, JOYKEEPER can last up to 2-3 years without recharging or replacing batteries.
  • Designed to be discreetly installed into your instrument. Nobody will ever notice.
