The Barr and Stroud Sine Rangefinder was a compact, hand-held device for getting a rough range estimate for purposes of station-keeping, fire- or torpedo-control.
It was found to be handier than the Weymouth-Cooke Rangefinders,but not as easy to read. Trials revealed it to be inferiour to the Weymouth-Cooke Mark III.[1]
