ABSTRACT:
A combination of a compass and a connecting arrangement. The compass includes a compass housing having a base wall, a circular wall connected to and upstanding from the base wall and a transparent window connected to the circular wall to define a sealed chamber in which is located the compass works. The compass housing has a radially outwardly extending flange thereon which is greater in dimension than the outer diameter of the circular wall. The connecting arrangement includes a strap for securing the compass housing to an archer's bow. The strap includes an elongated, uniformly thin strip of material having oppositely facing surfaces. The strap has a centrally disposed, circular-shaped first hole therethrough, the diameter of the circular-shaped hole being less than the diameter of the aforesaid flange. The compass housing is received in the circular-shaped first hole, the flange abutting the second surface on the strap. A pair of uniformly thin patches of material straddle the strap, the first patch having a circular hole therein through which the circular wall of the compass housing extends. The first and second patches are secured together with the strap being oriented therebetween to secure the compass housing to the strap. A connecting structure is provided for connecting the second patch to the archer's bow whereas additional connecting structure is provided for securing the ends of the strap together enabling the strap to encircle the archer's bow to effect a securement of the compass housing to the aforesaid bow.
