This jointed version of the IRIS Underdog is very easy to fish. Simply cast and retrieve the Underdog JTD and it will come to life just under the surface, with a unique flanking and swimming action. The IRIS Underdog JTD will run at a depth between 10 and 80cm. The slow floating action allows you to stop the lure for a moment and let it "sit" for a few seconds, just like a real prey fish.
