The FPV-POWER 12V Regulator is designed to be used with fishfinders needing a minimum of 11V to run. The reason is that at 11V, the battery will still have between 1/4 to 1/3 capacity left however the fishfinder will cut out as it hits its minimum operating voltage. The regulator is installed inline between the battery and fishfinder and will provide a constant 12V to the fishfinder right until the battery reaches its safety cutoff.
