Electronic Aids in Hunting: GPS and Rangefinders in Practice
Electronic Aids in Hunting: GPS and Rangefinders in Practice
Technology has become an integral part of modern hunting. Where hunters once relied solely on maps, compasses, and experience, today’s outdoorsmen and women have access to a range of electronic tools that can make hunting both more efficient and more ethical. Two of the most common devices are GPS units and rangefinders—tools that assist with everything from navigation in remote terrain to precise shot placement. But how are they used in practice, and what should Canadian hunters keep in mind?
GPS – Navigation and Safety in the Wild
For many hunters across Canada, a GPS (Global Positioning System) has become as essential as a rifle or bow. Whether you’re tracking moose in the boreal forest, navigating the foothills of Alberta, or exploring the backcountry of Newfoundland, a GPS provides reliable orientation even in areas where landmarks are scarce.
Route Planning and Coordination
A GPS allows you to mark waypoints, record routes, and easily find your way back to camp or your vehicle. This is particularly valuable on large Crown lands or in unfamiliar hunting zones. Many modern devices also allow you to share your location with hunting partners, improving coordination and reducing the risk of accidents.
Safety and Documentation
Beyond navigation, a GPS can be a critical safety tool. If you become injured or disoriented, you can relay your exact coordinates to rescuers. Some models even include satellite communication features, allowing you to send emergency messages when you’re out of cell range—a common situation in Canada’s vast wilderness. GPS data can also help document your movements for future planning or wildlife management purposes.
Dedicated Device or Smartphone App?
Hunters can choose between dedicated GPS units and smartphone apps that use built-in GPS functions. A handheld device typically offers better battery life, weather resistance, and reliability in cold conditions, while an app can be convenient if you already carry your phone. Regardless of your choice, always bring a paper map and compass as a backup—electronics can fail, especially in freezing temperatures.

Rangefinders – Precision at the Moment of the Shot
Rangefinders are another valuable tool that can significantly improve shot accuracy. They work by sending a laser beam toward the target and measuring the time it takes for the reflection to return, providing an exact distance reading within seconds.
Ethical and Accurate Shooting
Knowing the exact distance to your target is crucial for making a clean, ethical shot. Even small misjudgments in range can cause a bullet or arrow to hit too high or too low. A rangefinder helps you determine whether an animal is within a responsible shooting distance, reducing the risk of wounding and ensuring a humane harvest.
Integrated Optics
Many modern scopes and binoculars now include built-in rangefinders, allowing hunters to measure distance without switching equipment. This saves time and minimizes movement—an advantage when game animals are alert and easily spooked.
Practice and Skill Development
While technology enhances accuracy, it should not replace a hunter’s own judgment. It’s wise to practice estimating distances by eye and then verify with a rangefinder. Over time, this combination of skill and technology makes you a more capable and confident hunter.
Regulations and Ethics in Canada
The use of electronic aids in hunting is subject to provincial and territorial regulations. In most parts of Canada, GPS units and rangefinders are permitted, but devices that provide an unfair advantage—such as thermal imaging scopes or night-vision optics—are often restricted or prohibited. Always check the specific rules in your province or territory before heading out, and remember that ethical hunting is about fair chase and respect for wildlife.
Technology as a Support, Not a Substitute
Electronic aids can make hunting safer, more efficient, and more precise, but they should be viewed as tools that complement—not replace—the hunter’s own skills and knowledge. The best hunters remain those who understand the land, read the signs of nature, and act with care and responsibility.
When used thoughtfully, GPS units and rangefinders can elevate the quality of the hunt—for the hunter, for the experience, and for the wildlife itself.
