they seem to be best under a float most of the time , the constant depth setting keeps the jigs mostly off the cover if you cast well and know where to NOT cast said tandems .....:Rofl
even open water tandems seem to find stuff to get hung up on , I don't double much , but sometimes when I am not sure and or think they are all thru the water column and have the room to pitch said doubles , then I just might do it ....:highfive
