Accordingly, it would be advantageous to avoid concentrations of tension between dissimilar materials. Whenever there is a concentrated stress or tension between dissimilar metals, there is the likelihood of increased corrosion and strain which could cause the salt tablet to weaken prematurely. Additionally, in the prior art devices, the point of contact between the tablet and the opposing structure are necessarily formed of dissimilar materials, with the tablet being formed of salt and the opposing structure being formed from plastic, metal or some other non-dissolving material. The devices that rely on this bobber retention method fail to protect against inadvertent release in the manner used by the present invention, as the present invention instead redirects and redistributes the axial force in a radially outward direction. In other words, these devices tend to deploy when the fisherman least wants it to do so, i.e., when the fisherman is reeling in an aggressive fish, while the rod is being transported in a vehicle or when the rod is in storage. This method of operation, however, is prone to inadvertent bobber release, as the tablet breaks down to the constant force and moisture in the ambient atmosphere without the device having been submerged in water. The devices hold the bobber in place by directly opposing the force of the spring by placing the tablet in the way of the bobber's release. Traditionally, these devices hold a bobber in place by, in essence, applying a shearing force to a small section of a dissolvable tablet, such that the tablet is under a constant, compressing shear force that seeks to rip the tablet apart at the point of contact. sunken vesselsÄ®xisting water-activated bobber release devices are used for releasing a bobber when items, such as fishing rods, rifles or other items become submerged.
