Tandem Rigs are simple and can attach to either a umbrella rig (if you are not scared) ,daisy chain, or just run by themselves. They consist of a 3-way swivel connecting 2 baits usually the same type and color lures. When I make my tandem rigs I use 3 foot and six foot leaders to the 3-way swivel. You should ALWAYS place you heaviest lure to your shortest leader. Spring time I like to troll 4 and 6 ounce parachute lures with a stinger hook.
