摘要: The present invention is aimed to propose a method for minimizing erroneous shift water depth measurement mode by judging whether caused normal operation or detection and automatically getting out of the even in case mode. Instantaneous prevented when circuit 5 judges that value Ddpt from arithmetic processing exceeds predetermined switch 6 detects no contact, time information display returned on under conditions other than diving, an original situation precisely unexpected
