This equipment is capable enough to measure any known depth with sufficient accuracy. It has two recorders-one in scale ranges of 0-2, 000 metres and 0-2, 200 metres, and the other of 0-200 metres. The repetition interval of the sound impulses is 2, 000 metres or 2, 200 metres. The range of the second recorder can be picked out of the range of the first recorder under 100 metres step-phasing. Scale marks are fed independently of driving mechanism, and thus the synchronization between the synchro-oscillater and the drive-moter is continually shown on the recording paper. The time marks of 5 minute interval are also driven electronically with the synchro-oscillater. This equipment showed good performances on the field tests.
