The disclosure provides a system and methods of use pertaining to long-range fishing applications. One embodiment provides a long-range fishing-device delivery system that relies on a mounting shaft, a buoyancy module, and a fishing or payload module to house a variety of fishing devices such as a baited hook, an artificial lure, or a fishing accessory such as a depth sensor, temperature sensor, or fish finder. The delivery system leverages a launch force from an external launching apparatus such as a bow or slingshot to deploy the system and enclosed fishing device to a desired long-range location and depth within a body of water. Other embodiments are also disclosed.
