Here's a nice little site on fishing the tasmanian devils...Also, it shows deep diving tasmanian devils and jigging tasmanain devels..
LITTLE TASMANIAN DEVILŪ 7 gram - 1/4 oz. (38mm)* *The "Little Tassie Devil" is ideal for casting in small rivers and streams. Recommended trolling speed of 4km/h (2.4m/h) is sufficient to provide the unique action of flicking and swaying from side to side that will normally attract the most reluctant fish to strike. When Casting, vary the retrieve rate by flicking the rod tip.
ORIGINAL TASMANIAN DEVILŪ 13.5 gram - 1/2 oz. (52mm)* *The "Tassie Devil" is the original of the three sizes that Wigston's Lures commenced manufacturing in Australia in 1980. Performance as a trolling, casting, downrigging or jigging lure is best described as a great all-rounder. Recommended trolling speed is 4.5km/h (2.75m/h). The correct speed is indicated by a pulsating or nodding action of the rod tip.
BIG TASMANIAN DEVILŪ 26 gram - 1 oz. (78mm)* *The "Big Tassie Devil" is designed for larger fish and performs ideally as a trolling, downrigging, jigging or casting lure. Recommended trolling speed is 5.5km/h (3.5m/h) and the correct speed can be monitored by rod pulse. Downriggers or lead core line can be used to increase trolling depth.
A revolution in winged lure technology, the new Dual Depth Tasmanian Devil is capable of reaching depths similar to those achieved when using lead core line. This is achieved by the innovation of two towing points. The first tow point located on the head of the lure enables the lure to swim at 3.3m. The second tow point in the regular front position allows the lure to swim at 2.2m. One of the most versatile Tasmanian Devil lures available.
DUAL DEPTH TASMANIAN DEVILŪ 20 gram - 3/4 oz. (54mm)* *Suitable for Trout, Salmon, Bass, Steelhead, Redfin, Trevally, Tailor, Queenfish & Flathead. Recommended trolling speed is 3.5km/h (2.00m/h)
