1. A marine electronic device comprising:
a main unit;
a power input in connection with the main unit, wherein the power input is configured to provide energy to the main unit;
a secondary unit configured to store energy for processing sonar data, wherein the secondary unit is connectable to the main unit to provide stored energy to the main unit, wherein the secondary unit is configured to process sonar data in a first mode, and wherein the secondary unit is configured to provide power to the main unit from one or more capacitors of the secondary unit in a second mode;
a processor; and
a memory including computer executable instructions, the computer executable instructions configured to, when executed by the processor, cause the processor to:
determine whether the power input is providing energy within a predetermined threshold to the main unit; and
in response to a determination that the power input is not providing energy within the predetermined threshold to the main unit, cause the secondary unit to provide at least some of the stored energy to the main unit.
