Abstract
A warning notification device includes a sensor, a notification unit, and a processor. The processor is configured to calculate a water depth from an output of the sensor every predetermined time and to calculate a surfacing amount from a change in the calculated water depth every predetermined time. When a long-term surfacing speed condition, which is to be determined on the basis of the surfacing amounts of a first number, is satisfied or when a short-term surfacing speed condition, which is to be determined on the basis of the recent surfacing amounts of a second number smaller than the first number, is satisfied, the processor enables the notification unit to issue a warning of a surfacing operation.
