         7 . The sighting device as claimed in  claim 3 , wherein the securing means further comprises a third clamp member and a quick-release lever, the third clamp member is movably connected to the first clamp member, and the quick-release lever is rotatably connected to the first and third clamp members, wherein the rangefinder module is clamped between the first and third clamps in a horizontal direction by the rotating quick-release lever around an axis parallel to the horizontal direction. 
     
     
         8 . The sighting device as claimed in  claim 7 , wherein the rangefinder module has a protrusion received in a recess formed between the first and third clamp members. 
     
     
         9 . The sighting device as claimed in  claim 3 , wherein the sighting device further comprises at least one screw fastened through the second clamp member to the first clamp member in a direction angled relative to the vertical direction. 
     
     
         10 . The sighting device as claimed in  claim 3 , wherein the sight module comprises a sighting telescope having an objective lens portion and a lens barrel connected to the objective lens portion, and the rangefinder module protrudes from the objective lens portion in a direction parallel to an optical axis of the sight module. 
     
     
         11 . The sighting device as claimed in  claim 1 , wherein the sight module comprises a compound bow sight that has a ring-shaped frame and at least an aiming pin disposed in the ring-shaped frame, and the rangefinder module is disposed on a lateral side of the ring-shaped frame. 
     
     
         12 . The sighting device as claimed in  claim 11 , wherein the securing means comprises a first clamp member, a second clamp member movably connected to the first clamp member, and a third clamp member connected to the first clamp member, wherein the compound bow sight is clamped between the first and second clamp members in a first direction, and the rangefinder module is clamped between the second and third clamp members in a second direction perpendicular to the first direction. 
     
     
         13 . The sighting device as claimed in  claim 12 , wherein the first and second clamp members respectively have two hook portions to clamp the compound bow sight. 
     
     
         14 . The sighting device as claimed in  claim 12 , wherein each of the first and second clamp members has a curved surface that is shaped corresponding to the curved inner surface of the ring-shaped frame. 
     
     
         15 . The sighting device as claimed in  claim 12 , wherein the securing means further comprises a nut and a bolt engaged with each other, and the bolt extends through the nut, the first clamp member, and the second clamp member. 
     
     
         16 . The sighting device as claimed in  claim 12 , wherein the securing means further comprises a quick-release lever rotatably connected to the first and third clamp members, wherein the rangefinder module is clamped between the first and third clamp members by the rotating the quick-release lever around an axis parallel to the second direction.
