1. A fishing tip-up comprising: a signal, an upright support;
a swinging arm having first and second segments each of which terminates at a terminal edge at opposite ends of said arm, said arm being pivotal relative to said support such that when one of said segments pivots downward the other of said segments pivots upward, said arm being adapted to support a fishing line which extends downward selectively from either one of said terminal edges and to which a bait is attached for attracting a fish, whichever said segment from which said fishing line extends pivoting downward when said fishing line is subject to a downward force greater than a predetermined value; a normally closed magnetically opened switch provided in said support; and a magnet provided in each of said first and second segments for opening said switch, said magnets being of unequal magnetic strength and a selective one of which being normally proximate sufficiently close to said switch to cause said switch to remain open until said force of predetermined value causes said swinging arm to pivot with resulting separation of said proximate magnet from said switch with resulting closure of said switch and concurrent activation of said signal, further including positioning means for selectively positioning said arm on said support in two separate positions separated 180 degrees from each other, whereby one of said magnets of unequal magnetic strength may be selected to be proximate to said switch to maintain said switch in an open position with varied sensitivity, and a stand for immobilizing said support upright, said support being removably attached to said stand and rotatable between two separate positions separated 180 degrees from each other. |
