Figure 61

Figure 61. Electrosounder, used by the Italian Navy in 1954, employed a small explosive device which exploded on impact with the bottom and the sound subsequently was heard at a hydrophone on a ship. The use of explosives for depth finding was first suggested by a French engineer, Urbain Dortet de Tessan about 1850.
