wiseguy, it is a rig that actually looks like the frame of an umbrella (the wire frame) with tubes or rubber shad hanging off... 9 baits so as to simulate a school of fish, which is trolled with stainless steel wire which depending on how far out, will act as a sinker... 100 feet in length equals 10 feet deep. 300 feet of wire with an umbrella rig on the end trolled 30 feet deep with the potential of being hit by 1 or more blues or bass is the time when you need everything to work just right, from the rod holder all the way down to the rig.
