At about 6" long and weighing in around 1-5/8 ounces this junior version of the original bottle darter are for those that like to throw smaller plugs. 

Word from Larry:

The "Junior" Bottledarter, basically the same action as the full size BD but with a shallower depth of approx. 3-3 ½ ft.

All NBT and SW swimming lures fish best if the speed of retrieve  is varied and "jigging" or "twitching" is included.
