Abstract
A boring element of a ground boring device includes a housing having a receptacle, a transmitter arranged in the receptacle of the housing and supported in the receptacle for movement in a longitudinal-axial direction of the boring element, and a front buffer connecting the transmitter with the housing. The transmitter moves towards a rear in the receptacle as a result of a deformation of the front buffer, when a rear percussive impulse is applied to the boring element, without the transmitter coming directly into contact with another part of the boring element.
