Mastering Your Hunting Optics
Binoculars, rangefinders, spotting scopes and field glassing tactics
Whether you are scanning distant ridges or closing the gap on a trophy animal, your optics are among your most critical tools in the field. However, high-quality gear is only effective if you know how to use it to its full potential. Experienced hunters understand that optics should be more than expensive accessories worn around the neck. They are essential instruments that require specific tactics to master.
To help elevate your glassing game, the experts at Venture Hunting & Outdoors have put together a practical guide on using binoculars and rangefinders effectively. From systematic scanning techniques to quiet harness setups and smart rangefinder placement, the right approach can help you find animals sooner, move more efficiently and make better decisions in the field.

Strategic Glassing
The primary goal of glassing is to locate animals before they locate you. This process often starts long before the sun comes up. A successful glassing session is not just about owning a good pair of binoculars. It is about being in the right place, using your eyes carefully, managing your movement and giving yourself enough time to properly scan the country in front of you.
In open country, on ridgelines, across gullies or when looking over broken timber, animals can be extremely difficult to spot with the naked eye. A flick of an ear, the curve of a backline, the shine of an antler or a change in texture on a hillside can be all you need. Binoculars and spotting scopes help pick up those details, but only if you slow down and work the country properly.
Preparation and Comfort
A successful glassing session often begins by reaching an elevated glassing knob before dawn. Once you have reached your vantage point, the most important factor is getting comfortable. Whether you are using binoculars or a spotting scope, being in a stable, comfortable position allows you to remain still and focused for longer periods, which is essential for spotting well-camouflaged game.
If you are uncomfortable, leaning awkwardly or constantly shifting around, you are more likely to miss movement and more likely to give away your own position. A comfortable seat, a steady pack, good body position and a clear view of the area you are scanning can make a major difference during a long glassing session.
Light and Search Patterns
Lighting plays a massive role in what you can actually see through your glass. Ideally, you want to glass with the sun behind you, illuminating the face of the mountain or terrain you are scanning. This helps bring out detail, improves contrast and makes it easier to pick out animals that would otherwise blend into the background.
Looking directly into the sun is far from ideal, but if it is necessary, you can improve image quality by using your hand to shield the front of the lenses. This simple technique reduces glare and improves clarity, even in difficult lighting conditions. It is a small habit, but it can help you keep scanning effectively when the light is not working in your favour.
Rather than scanning a hillside randomly, use a methodical approach to ensure you do not miss any nooks and crannies. One highly effective method is to treat the terrain like an Excel spreadsheet. Start at the top left of the area you are scanning and move horizontally across a row. Once you reach the end, drop down to the next level and move back in the opposite direction.
By being systematic, you ensure that your optics' field of view covers every inch of the landscape. This is especially useful when animals are bedded, partially hidden or standing in broken terrain where only a small part of the body might be visible.
Stability in the Field
In the field, you will not always have a tripod or perfect base. If you are glassing while walking or if there is a steady breeze, you can increase your stability by bracing your binoculars against your gear. The steadier your image is, the easier it becomes to identify detail and movement at distance.
A simple trick is to grab the brim of your hat or cap while holding your binoculars. This creates a more rigid support system and helps prevent your view from being rocked around by the wind. It can also reduce hand shake when you need to make a quick scan without setting up a tripod.
Field tip: Slow glassing is usually better than fast scanning. Pick a section of country, stabilise your view and work through it in a deliberate pattern before moving on.
Stealth and Gear Setup
The way you carry and access your optics can be just as important as the optics themselves. Every movement and sound in the bush matters, especially when you are in close quarters with animals. A well-set-up binocular harness, a secure rangefinder position and a quiet lanyard system can all help reduce unnecessary movement and noise.
While many binocular harnesses use magnets for easy closure, some experienced hunters avoid them for one primary reason: noise. In the final stages of a stalk, the slap of a magnetic lid closing can be loud enough to alert a pig, goat or deer.
Choosing a harness that can be opened and closed silently, such as those with manual tuck closures, can be the difference between a successful hunt and watching your quarry run away. A good harness should also protect your optics from the elements, such as rain, while remaining quiet and easy to use.
Rangefinder Placement
For bowhunters, efficiency of movement is paramount. If you are a right-handed shooter, you will likely be holding your bow in your left hand during the final part of a stalk. Therefore, it makes the most sense to keep your rangefinder on your right-hand side.
Having it on the opposite side requires unnecessary movement across your body, which can increase the chance of being spotted by an animal. A small gear placement decision like this can have a big impact when an animal is close and every movement counts.
Lanyard tip: Attaching your rangefinder to your harness with a short cord or lanyard is a smart tactical move. It allows you to quickly range an animal and then simply let go of the device to prepare for your shot.
The cord prevents the rangefinder from thumping onto the ground or making noise, allowing for a split-second transition that can determine whether you are able to draw your bow in time.
Rangefinder Tactics
A rangefinder is an integral bit of kit for modern hunters, providing the data needed for ethical and accurate shot placement. This is especially important for bowhunters, where small distance errors can make a big difference due to the trajectory of an arrow.
One of the most important features to look for in a rangefinder is angle compensation. When hunting in steep hills or mountains, the vertical distance to the target is not what determines your shot's trajectory. It is the horizontal distance. A rangefinder with angle compensation automatically calculates this for you, whether you are aiming uphill or downhill.
Do not wait until an animal is standing in front of you to start measuring distances. When you settle into a spot to call or wait, take the time to range various landmarks. Range rocks, bushes, trees or even cow pats in an open field.
Knowing that a specific shrub is 20 metres away and a rock is 30 metres away allows you to react instantly when an animal appears. This is especially critical for bowhunters who must account for the significant trajectory of an arrow.
Planning the Stalk
Rangefinders are also invaluable for planning your approach in open country. By ranging the animal and the available cover between you, you can make informed decisions. Knowing that a deer is at 100 metres but the last bit of usable cover is at 50 metres helps you visualise the stalk and increases your chances of success.
This is where a rangefinder becomes more than a tool for the final shot. It becomes part of your planning process. You can map out where you need to move, how far you can close the gap and when you may run out of cover.
Bowhunting reminder: Pre-ranging your environment can save time when an animal steps into range. If you already know the distance to nearby cover, rocks, trees and open gaps, you can focus on staying calm and making a clean shot opportunity.
Recommended Optics Gear
From binoculars and spotting scopes to specialised harnesses and two-in-one rangefinding binoculars, there are many options to choose from. The right setup depends on your hunting style, the country you hunt and how you prefer to carry your gear.
If you spend time scanning ridges, open flats or distant gullies, quality binoculars and a stable glassing system should be high on your list. If you are bowhunting, a reliable rangefinder with angle compensation and quick access can be just as important as the bow itself.
