Embodiments of the modular fracking ball assembly can include, but are not limited to, a measurement assembly, a shock absorbing layer, and an outer shell. The shock absorbing layer can encase the measurement assembly and the outer shell can encase the shock absorbing layer and the measurement assembly. The outer shell of the modular fracking ball assembly can be replaced with another outer shell when a change in parameters of the modular fracking ball assembly is needed. For instance, an overall diameter or a specific gravity of the modular fracking ball assembly can be changed by swapping outer shells.

A fish or fish bait preservation apparatus and method utilizing ice as a coolant and piping bait or fish containing water therethrough to maintain this water at an automatic electronically controlled temperature and returning this water appropriately cooled to a fish or bait tank through a conductor having an aerating nozzle.

A bilge pump switch sensing the presence of bilge water by measuring the density of water by using an ultrasonic field penetrating the water, the field extending through the housing of the switch. Thus the internal elements of the switch are isolated from any contact with the water. The ultrasonic field detecting the presence of water activates sensing means in said switch housing to activate the pump, delay means being provided against false pump starts due to wave action as caused by a rocking boat.
