Introducing the 'iGrave': the GPS device that lets you track your relative's coffin

American funeral directors have unveiled the first ‘iGrave.’

It uses GPS satellite tracking to allow relatives to find their loved ones in a natural burial site.

Everyone buried at The Preserve, a 1.5-acre natural burial site in Lafayette, Indiana, receives a GPS transmitter disk in the center of their casket, or in the grave if there is no casket.

The battery powered devices last for several years, and are roughly the size of a hockey puck.

They are based on systems usually used to locate buried water pipes or gas mains.

The high tech burials are designed to allow staff and family members to find their loved ones exact location in a burial ground where graves are not marked.

Staff and family will be given special readers to direct them to the correct area.

“It’s like reading a bar code,” said Joe Canaday of Hippensteel Funeral Service and Crematory.
