Quick Answer
A rangefinder is not strictly necessary for bowhunting deer, especially in familiar terrain, but can be very useful for determining precise ranges and making accurate shots, particularly in dense or unfamiliar environments.
Understanding the Terrain
When bowhunting deer in the Wisconsin Northwoods, it’s essential to understand the terrain and the layout of the forest. Familiarize yourself with the woods, including the location of ridges, valleys, and any prominent features that can affect line-of-sight. Even without a rangefinder, you can estimate ranges by observing the size of trees, the height of vegetation, and the angle of the terrain. For example, a mature buck at a 20-yard range will appear significantly larger than one at 50 yards.
Effective Use of Rangefinder
If you do choose to use a rangefinder, make sure to use it in conjunction with other field techniques, such as reading body language and observing the deer’s behavior. For instance, if a buck is standing broadside at 25 yards and you know the angle of the terrain, you can use the rangefinder to ensure that your shot is within the effective range of your bow. Consider investing in a rangefinder with a high degree of accuracy and a compact design for easy carrying in the woods.
Techniques for Estimating Ranges
There are several techniques you can use to estimate ranges without a rangefinder. One effective method is to use the “yardstick” approach, where you measure the length of your arrow and compare it to known objects in the environment. For example, if your arrow is 28 inches long and you can see the tip at eye level with a 5-foot-tall sapling, you can estimate the range to be around 70 yards. Practice these techniques during off-seasons to become more accurate and confident in your shot.
