A flat plate has means for connecting a fish bait to the rear portion thereof and has a link swingably attached to the front portion thereof with an eye on the end of the link for attachment to a trolling line. An upstanding fin projects from the top of the plate and has a slot located in the forward portion of the fin and extending obliquely rearwardly of the plate for receiving and detachably holding the link in a position which causes the plate to dive when it is drawn through the water. The sides of the slot are flexible and there is an adjustment screw to adjust the amount of force required to detach the link from the slot.
