To use tandem hooks on your Tomic Classic or Tubby, double up a strong flexible line and knot it to desired length. Loop line through the trailing hook and then through the pin. Ensure that the leading hook is on a split ring and placed ahead of trailing hook line, as this will help eliminate any tangling problems.
For a faster troll, lengthen the line, so the hook hangs at the back of the tail. For a slower troll, shorten the line, as the hook will fall away from the plug.
For tandem treble hooks you may want to try the Multi, which comes with a molded tail ring to accommodate a back hook.
