A method and apparatus for determining when a shipment undergoes excessive vibration or bouncing is provided herein. It consists of a floater specifically linked to a propelling system comprising a pedal mechanism with discoid branches with protected pedals actuating two cog wheels secured to two rods connected by pivot pins and sliding in two tubes at the end of which are fixed aquatic flippers. This lead is implanted by an accessory with a needle having a puncture pointed free end and an opposite end mounted on a gripping end tip, and a releasable device for holding the microcable along the length of the needle. The plug connector and the guide pin structure are disposed on the base. In various embodiments, the seed layer is comprised of VMo or VW.
