Remember the old TV show “McHale’s Navy?” I was fascinated every time lieutenant commander Quinton McHale launched a torpedo over the side of the PT 73. For McHale, the torpedo usually bubbled off only to miss its

mark, but last year a new torpedo hit the Great Lakes fishing scene. These new directional sinkers, known as Torpedo Divers, efficiently and easily hit their targets more times than not.

Torpedo Divers have a variety of applications but really shine on calm days during the dreaded midday bite. Essentially, Torpedoes are not divers, but sinkers, shaped like a torpedo that attach to your fishing line via a clip and an 18-inch leader. Their hydrodynamic design allows them to penetrate deeper in the water column than traditional sinkers. They come in four sizes ranging from the 21/2-ounce Snapper to the 13-ounce Musky.

The directional Torpedoes have a fin that you can adjust to make the sinker run out to the port or starboard side and are great alternative to the aggressive presentation of Dipsies or Walker Divers when the early bite shuts off. The directional Torpedo allows you to turn the same rig, minus the Dipsy, into a stealth presentation. And yes, you can use the same rod and reel that your braided diver was on.

On the business end I like to run spoons with a small, 30-pound ball bearing swivel from Sampo or Dreamweaver and a 10- foot, 8- to 20-pound fluorocarbon leader. I tie the leader onto a swivel, and that is tied to 30-pound test braided line—the same line that Torpedo inventor Matthew Sawrie used to put together the company’s intricate charts.

The same spoons that work on leadcores and light line riggers seem to work great on the Torpedoes, too.

The rig is easy to set. Simply let the spoon (or flasher/fly or body bait) out 10 to 100 feet and attach the Torpedo to the main line with the clip. Next, make sure the Torpedo clears any rigger lines you have in the water and 

then let the rig out until you hit your target depth—easy to do with the charts that come with the weights. When a fish strikes, you will be amazed at how little drag the rig puts on your rod or the fish. This results in a much better catch rate. The minimal drag is due to the sinker’s design and the angle of the dropper line. As the fish approaches the boat, you simply and

quickly pull the clip and sinker off of your line and finish the fight.

The Torpedo website has depth charts for the various sizes of sinkers, but the actual running depth will vary depending on trolling speed, current, wave texture and lure selection. My advice is to spend a little time experimenting with these rigs when you first run them. Honestly, it took me a few trips on the water until I figured out how and when to incorporate them into my spread, but it was worth the effort.  

When running the angled sinkers in place of divers, remember that you are putting a line into your spread slightly out to the side of the boat, but your lure can be adjusted to run further behind the boat than a traditional Dipsy. The Torpedo is also very quiet as it moves through the water, resulting in a very stealthy presentation.

Torpedoes have another practical application; they can help extend the reach of anglers with a limited budget or a rod selection.  You can simply add a Torpedo to a lead core or copper rig and sink the entire rig deeper in the water column. For example, maybe your longest leadcore rig is a six-color (60 yards of leadcore line). Let all the leadcore into the water and attach the Torpedo of choice to the backing. Then, let out enough backing to take the leadcore as deep as you want your lure to go. For example, if you figure 5 feet deep per color, six colors of leadcore is already taking your lure 300 feet deep. Add an 8-ounce Musky Torpedo, let ouut 100 feet more backing,  and at 2.4 mph the Torpedo will get down 45 feet - the lure behind your six color  is now down into the 75-foott range. Snap on the 13-ounce Cuda (the biggest), let 100 feet of line at 2.4 mppg and you achieve 55 feet more depth, putting your lure about 85 feet deep.

You can also use Torpedoes with shorter segments of copper. For example,  you can run 75 or 150 feet  of copper with braided line backing. The larger Torpedo can easily sink your lures past 100  feet deep. Sawrie says you can reach 150-foot depths with Torpedoes and copper.

You don't diminish the hypnotic effect of leadcore as the Torpedo is in front of the dancing leadcore. You can  also run these versatile  tools with a side planer (I like Church Walleye Boards), which adds a surge-and-pause motion and takes the line to the side of  the boat.

If you're serious about Great Lakes trolling you might  want to try Torpedoes this year. Whole Torpedoes catch fish all day long, these directional sinkers really sparkled during the tough mid-day bite last year.  I look forward to hearing how creative anglers incorporate these new sinkers into their spreads this season.  Post your resullts on GLA
