Yellow Paravane Diving trolling Board is Ideal to get the lure down to a depth that the fish are at. Great for chasing Mackerel and pelagic around bait schools or for chasing Snapper, Jacks, Coral trout and other reef fish along that sharp drop off in the salt, Can also be used in fresh water and is Ideal when the trout or Bass are sitting deep.
I use this for School Mackerel in Moreton bay and have found it a deadly weapon. It is a must in my tackle bag for sure and I have 2 spares in the boat.
