The principle of the tandem mount for cephalopod fishing
The tandem rig is a leader on which a jig called a teaser is attached and a classic jig that acts as a casting weight. The teaser jig can be attached in different ways using different knots. The simplest knot is usually a loop that is cut in the center to create two separate strands.
Although this is the most used rig, it is far from being solid and reliable. The most efficient rig is the special tataki rig, which consists in making a small loop on which the teaser is fixed, then attaching the classic jig about 30 centimeters below. The tandem rig is not very aerodynamic and does not throw as well as a classic single rig, but it offers two different jigs to the cephalopods.
Doubling the odds
When we make a tandem rig, we need a very small jig, floating if possible. We can then choose among the different existing models as well as the different colors to increase our chances of finding the pattern.
This technique works particularly well when you don't know the spot you are fishing or when your last cephalopod trip is not recent. Finding the color that works, whether natural or flashy, will be twice as fast as with a single jig. Once you have found the color or size that works with the buttons on one jig or another, you can then modify the second jig to get as close as possible to the one that already works.
Some tips
The tandem mount is particularly effective when large schools of squid are moving together, especially in the early season. These squids are often small and very aggressive thanks to the food competition. It is then not rare to make doubled, although it requires not to make the first squid spit when it bites on the jig.
Don't forget to rig your leaders slightly stronger than usual, as two squids pulling in opposite directions of the rig could break the line if your knot isn't perfectly made. Also, check the total weight of your two jigs so you don't exceed the power range of your rod and risk damaging it. Your animations will have to be a little bit stronger, so as to compensate for the resistance that the teaser opposes to the swim of the classic jig.
