1) They have a very cool darting action that really catches the attention of a variety of fish. I've caught bass, trout and even Northern Pike on these plugs.
2) Also, the lure has a hook harness that I have not seen with other lures. These harnesses usually have two treble hooks and thread through the nose of the lure where they can be attached to a swivel or tired directly to the line.
I've usually fished these in combination with a Lurh Jensen Dipsy Diver, which I'll detail below.
The setup is simple. You'll want to use a sturdy trolling rod and reel such as the following Dipsy Diver Model from Cabelas. I usually use 20lb test mono on the main line that will be tied from the rod to the Dipsy Diver, just as you would tie a lure to the end of your line. You then just need to add a leader to the back of the diver, I usually use 15 lb test but this can vary depending on the size and type of fish you are going after. To the other end of the leader you tie your lure, such as the J-Plug I detailed above.
Once you have your rig set up, you are ready to hit the water and do some fishing! The only other note I have is that there is a release, much like that of a down rigger. When trolling, your rod will be bent quite a bit (this is normal due to the tension the diver applies); once a fish bites and is on the line, the added weight and fight of the fish will "throw" the release and the Dipsy Diver will stop diving and you can easily fight your fish to the surface. If you need to check your line for weeds, etc while trolling, you can give a good tug (just like you were setting the hook on a fish) to "throw" the release manually. This will allow you to retrieve the diver rig. Don't try to reel in the diver without doing this as it will be quite difficult!
If you've used either of these, please let us know of your success stories as we would love to hear what color combinations you favor!
