Abstract
A downhole catcher device comprises a catching mechanism which is configured to be transferable between a first mode and a second mode. The catching mechanism is further configured for passing by a first operation element if the catching mechanism is in the first mode and for catching a second operation element if the catching mechanism is in the second mode. The transfer between the first and the second mode is triggered (or effected) by a downhole tool which is operated by the second operation element.
