A '''Torpedo Sight Corrector''' was a British apparatus suggested by {{LCommRN}} [[William Frederic Wake-Walker|William F. Wake-Walker]] to demonstrate the effect of [[Torpedo Director|director]] errors for men using the [[Torpedo Attack Trainer]].{{ARTS1916|p. 34. (A.L. G. 6788/16)}}

==Design and Use==
The device combined an adapted torpedo director whose various bars could be locked down with a target ship.  It would be used after a trial run on the torpedo attack trainer and illustrate, in debrief manner, how the sailor had performed.

A target ship image of appropriate scale for the range in the training scenario at which the sailor had fired, and would be positioned in a suitable inclination to the user.  The sight bar is aligned on the target and locked down and the enemy bar set for enemy speed and heading.  The torpedo bar would then be locked down and the sight bar unlocked so the enemy bar could then be adjusted to the actual speed and heading of the enemy in the training scenario just undertaken.  This causes the sight bar to move, and a spot of light traces the actual place in the enemy line through which the torpedo would have passed.{{ARTS1916|p. 34}}

==Allocation==
By mid 1919, 110 of these instruments were under manufacture, and some had been received and supplied to ships and bases.  The intended allocation (1 each unless otherwise noted) was to be:{{ARTS1918|pp. 228-229}}
