If you are planning to hunt at night, you will need a thermal or night vision scope to be able to acquire the target successfully. But, while both of these devices will allow you to see at night, there are differences between the two.
Each has its own dedicated application, and each has pros and cons.
Let’s take a look at the differences, so that you can easily choose the best option for you.
You need to know the basic difference between thermal scopes and night vision scopes so you can choose the one that’s perfect for your hunting situation. Hopefully, the following section will make the differences between the two clear. So, keep reading!
Thermal Scopes And How They Work
The word “thermal” refers to anything related to temperature or heat.
Thermal scopes detect the heat or temperature of the target and use the radiation to generate the image.
The image can be generated in black and white or various colors depending on the device. The image will becomes lighter or darker with the increase or decrease of its radiation. Therefore, warm objects look brighter through the scope.
Thermal scopes detect the heat of a target and use radiation to generate the image.
Pros and Cons of Thermal Scopes
Unlike night vision devices, thermal scopes can be used both in the day and at night. And, because they use radiation or heat source to render the image, you can easily detect objects even if they are hiding or camouflaged.
In addition, thermal scopes can cover a larger distance than night vision scopes.
On the down side, during extreme cold, thermal scopes become blind.
Additionally, thermal scopes are heavier and more expensive than night vision scopes.
Some thermal scopes render images in colors.
How Night Vision Scopes Work
Night vision scopes work quite differently than thermal scopes. Some night vision scopes render images in a green hue and rely heavily on a light source to render them. The light source can be ambient, like that of the moon, the stars, or the surroundings.
If there is no light at all, the infrared illuminator (IR) is used to generate light. Luckily, the IR is not visible to the naked eye. Therefore, your prey will not be alerted.
Pros And Cons Of Night Vision Scopes
Night vision scopes are lighter and also less pricey than thermal scopes. They are available in various models and generations. Therefore, you can easily choose one according to your budget and requirements.
Since night vision scopes rely on an available light source, an unfavorable environment can affect the visibility. For example, in the fog, rain, snow, and dust, night vision devices are not as effective.
Additionally, night vision scopes can’t cover long distances as well as thermal scopes can.
Night vision scopes rely on a light source like the moon or stars.
While hunting at night, you need to identify the target as your desired game animal, otherwise, you may end up shooting something else. And the choice between night vision and thermal scopes depends on the shooting environment.
Thermal scopes can detect animals from long distances, but could be confusing for hunters if there are other moving targets in the field of view.
Thermal scopes can easily detect animals or moving objects from a long distance whether it is day or night. Their detection is better than night vision scopes. Even in the roughest weather, they can help you see (except in extreme cold).
However, one thing to keep in mind is that thermal scopes render images in black and white, or in shades of multiple colors, which may be confusing for hunters and shooters if there are other moving objects in the target area. If this is not going to be an issue for you, then a thermal scope would work fine.
You might be new to the sport of bowhunting and be looking to learn all you can about it.
Or, maybe you are a seasoned bowhunter wanting to test your knowledge of the parts of a compound bow.
Either, way this one’s for you!
Parts of A Compound Bow | Interactive Diagram
In the interactive diagram below, you can click/touch the NUMBER of the parts in the chart below to reveal the names of the parts. You can read more about what each part is and does in the sections below the diagram.See how many you can get right!
Compound Bow Parts | Piece-By-Piece
In the above diagram of the Nexus2 by Prime Archery, you can view the parts of a compound bow. Find out more about what each part does by clicking the words below:
On a compound bow, the cams are the round, or oval-shaped discs that work much like a block-and-tackle pulley system. The cams are connected to the axles of the bow.
The cams act as the “multiplier” of the energy of the person pulling the bow string. This allows the bow to store more energy than the person pulling the bow string is actually exerting.
The bow has a “back wall” where the cams will not turn any more. This is where the archer is at “full draw.” At this point, there is a percentage of “letoff” that allows the archer or hunter to hold the force of the bow at a fraction of the actual pounds of pull being exerted.
For example, a bow that is set to a 70-lb draw weight with a 70% letoff will only take 21 lbs of force to hold at full draw. The energy is stored in the bow’s limbs until the archer releases, which unleashes the multiplied energery, propelling the arrow toward its target.
Limb dampeners reduce the noise and vibration throughout the limbs and riser of the bow.
When the hunter or archer releases the arrow the sudden and powerful uncoiling of the string on the cams produces vibration, which causes noise. The limb dampeners help to absorb that vibration, resulting in a quieting of the bow.
This absorption by the limb dampeners is especially helpful in reducing noise when hunting deer or other wild game and also reduces the amount of vibration that is transferred to the archer.
A compound bow’s limbs are connected to the riser and store the energy that is collected when the string is pulled and the cams turn. When the string is released, the energy from the limbs is transferred to the arrow, which propels it through the air.
Most compound bow limbs are made up of fiberglass or composite material. Some bow limbs are solid, one-piece limbs. Others are “split,” having a gap between both sides of the upper and lower limbs.
4. Limb Pivot
Where the limbs pivot and flex on the riser.
5. Limb Pocket
The limbs of the bow rest in the limb pocket. These can be made of machined aluminum, ABS plastic or other composite materials. The limbs of the bow are secured in the limb pocket by the limb bolts.
6. Limb Bolt
The limb bolt is the crucial piece in connecting the limb pockets, which hold the limbs of the bow, to the riser.
Limb bolts are typically allen wrenc adjustable. Tightening the limb bolts increases the draw weight poundage of the bow. Loosening the limb bolts will decrease the draw weight poundage.
It’s very important that any adjustment to the limb bolts be made in the same increments. If the adjustments are uneven, the bow’s cams could get out of time, causing an improper tune.
If you need to adjust your bow’s draw weight, it’s a good idea to back the limb bolts all the way down and then start moving them both up the same amount.
The riser is the vertical portion and foundation of a compound bow. The limbs attach to it and it also serves as the fastening point for accessories such as the sight, arrow rest, grip, stabilizer, quiver, etc.
8. Sight Mounts
Sight mounts are holes in the riser that serve as the attaching point for the bow’s sight. The archer will look through the peep on the bow string and at the pin(s) of the sight to aim at the target or game animal.
9. Cable Guard
The Cable guard runs perpendicular to the bow’s riser. It keeps the bow’s cable out of the way of the arrow’s line of fire. It typically has rollers and/or slides attached to it to aid in keeping the cable on track.
10. Rest Mounts
Rest mounts are holes in the riser that serve as the attaching point for the bow’s rest. The rest is what holds the arrow in place while the archer is drawing and releasing the arrow.
There are many different types of rests. Some use prongs that the arrow will rest on, while others hold the arrow up and then fall out of the way when the arrow is released. Others, called containment rests, completely surround the arrow until it is fired and typically have no moving parts.
11. Arrow Shelf
The arrow shelf is the area of the riser where the arrow sits on the rest. While the rest typically holds the arrow off the shelf on compound bows, traditional bows (non-compound) usually have the arrow resting directly on the arrow shelf.
12. Stabilizer Mount
The stabilizer mount is a universal size threaded hole in the riser that is used to attach a stabilizer to.
The stabilizer helps balance and thus “stabilize” the bow when drawing and shooting, and also typically has vibration dampening properties. In essence, it helps the bow resist movement during the draw cycle and when shooting.
The back of the stabilizer also typically serves as the fastening point for the wrist sling.
The Axle is what holds the cams, in the same way a car axle holds its wheels. The cams have a hole in the center. The axle goes through the center of the axle and attach to the limbs.
14. String Splitter
Bows with parallel limbs (which eliminate cam lean) will have a string splitter. On these types of bows, the main part of the string that the archer attaches the release to “splits” just before the cams.
The splitter is what essential turns the single string into two strings, each going around its respective cam.
The cable(s) runs between the bow’s cams. They assist in moving the cams of the bow when the string is pulled back by the archer. It’s important to replace your cable(s) as well as your string as recommended per the bow manufacturer’s instructions or on the advice of your local bow shop.
The string of compound bow serves several functions. It is where the archer will connect their release. It is what the archer pulls (or draws) back and releases to launch the arrow.
Many archers will utilize a “D loop,” which attaches to the bow string and serves as a way to quickly attach the release to the string and also improves accuracy.
You should always inspect your string before and after shooting and hunting. A damaged string could end up being a broken string, which could result in serious injury to the shooter or others.
Any cuts or fraying should be addressed immediately and it is recommended that you take to your local bow shop for an assessment.
The “center serving” is coiled thread wrapped around the center portion of your string where you would nock an arrow and attach a D-loop. The center serving protect the center section of the string from wear and tear that results from nocking arrows as well as drawing and shooting the bow.
There is also serving material on parts of your bow string that go around the cams or through rollers that are attached to the cable guards. This helps the bow string stay together, especially in places that are likely to received the most friction.
18. Nocking Point
The nocking point is where the arrow, by way of the arrow nock, attaches to the bow string. The D-loop attaches above and below the nocking point.
The grip is the part of the bow that you hold while shooting. Grips are made of various materials such as wood, rubber, plastic, metal, etc.
The grip can also be a source of inaccuracy. For example, if you hold the grip too tightly, or twist the grip while shooting, you can cause your arrow to go off-course from where you were aiming.
20. String Stop
String vibration is a large cause for noise when a bow fires. A string stop helps dampen that vibration and thus reduces unwanted noise. The string stop is a rubber part that is often mounted on a post that is directly opposite of the front stabilizer.
The string stop not only helps dampen vibration, but also aids in better accuracy for the shooter, often resulting in tighter arrow groups at the target.
21. Cable Splitter
On some bows, the cable splitter is a ring that connects the cable to two separate cables, thus dampening vibration and noise of the cable during shooting.
“Axle-to-axle” is not a part of a compound bow, but rather a reference to measurement. Axle-to-axle is the measurement from the center of one cam to the other. The axles go through the center of the cams.
This axle-to-axle measurement is often used to determine how forgiving the bow will be in regards to arrow flight accuracy when taking farther shots.
A bow with a longer axle-to-axle height may be more forgiving that a shorter one, but may also be difficult to maneuver in tight-quarter hunting scenarios.
23. Brace Height
The “brace height” is not a part of the bow, but rather a measurement, in inches, of the distance between the “throat” of the grip to the center of the bow’s string.
A shorter brace height means a longer “power stroke,” which is the distance from the grip to the center of the string when the archer is at full draw. A longer power stroke typically means a faster bow, as it increases the amount of time that the arrow is attached to the string.
There’s nothing like the adrenaline rush of being in close to a deer or other wild game and releasing an arrow that finds its mark.
But, what if you’ve never felt that rush? What should you know to begin the quest of being a successful bow hunter?
In this article we will do our best to get you started in the right direction. Let’s just call this N1 Outdoors’ Bow Hunting For Beginners 101.

So, What Brings You To Bow Hunting?
Maybe you’ve always hunted with a rifle or other firearm. Maybe you’ve mastered gun hunting and simply want to try your hand at a new challenge.
Or, maybe you’re totally new to any type of hunting and just want to learn what this bow hunting thing is all about.
Whatever your situation or age, we think you’ll find that bow hunting is not only fun (you’ll want to say “Bowhunt Oh Yeah!”), but helps teach patience, discipline, attention to detail and focus. And, there is certainly a special sense of accomplishment knowing you have been able to take an animal at close range and provide meat for your family and friends.
If you haven’t taken your state’s hunter safety course, be sure to sign up and do that the first chance you get. This will help you learn safe hunting practices whether you are hunting with a bow or a gun.
You will also learn the hunting laws and regulations of your state, deer hunting tree stand safety, as well as learn how to identify game.
It’s possible that if you’re interested in learning to bow hunt, that you’ve already been watching videos or TV programs about bow hunting. But, if not, there is certainly no shortage of videos about bow hunting tips. And, while videos are great visuals to learn from, don’t discount the wealth of knowledge you can glean from bow hunting blogs and articles.
When getting started in archery, it’s a good idea to talk to your local bow shop for recommendations on what type of archery equipment and supplies you should begin with.
Your local bow shop is a great resource for anyone wanting to begin their bow hunting journey.
You don’t have to look long on social media to know that there are more than a few companies pushing their archery equipment and supplies. Of course, they all look good and sometimes it’s difficult to know what exactly you need.
As a bow hunting beginner, you may be overwhelmed with the choices of bow hunting equipment that is currently on the market. Your local bow shop can help you find your way through the sea of bow hunting advertisements to equipment that’s right for you.
The bottom line is that your local bow shop should provide you with a wealth of information when it comes to figuring out your equipment needs. And, of course, it’s always great to support local business, right?
Once you have decided on and purchased your bow hunting equipment and supplies, it’s time to do some target practice! But, before you sling an arrow, you need to inspect your equipment. Be sure you don’t have any cracks in your bow limbs, fraying of your bow string, or nicks or cuts in you bow cams . Also, be sure you have waxed your bow string recently.
You may have a local range or archery shop to shoot at, but you may also choose to buy your own target for practice at home.
If you choose to shoot at home, always be sure you set up your target in a safe location where there is no chance of an arrow shooting toward any individual. This includes never shooting towards houses, streets, sidewalks or any other location where people may be standing or passing by.
It’s also a good idea to place a backstop of some kind behind your target. This will help to block an errant arrows that miss the target. Be sure your backstop is much larger than your target.
Once you have gotten familiar with the operation of your new bow hunting equipment by shooting at a target, you can start to prepare for various bow hunting scenarios.
While shooting at a stationary target is certainly something to master, deer and other game animals don’t always still and broadside, allowing you to take a perfect shot. So, you should practice shooting your bow from various positions, including inclines, declines and sitting positions.
You may already be a hunter that is learning to bow hunt. But, if this will be your first hunting trip, be sure before you get your hunting license before your first trip.
You can contact your state’s Department of Natural Resources to purchase a license. Some local outdoors shops also sell hunting and fishing licenses. You can also go online to purchase a license for the state you live in.
As you get ready to take your new bow hunting skills to the field or the woods, continue learning as much as you can from experienced bow hunters. Be teachable. Your learning curve will be much less steep if you listen well and put into practice what you’ve learned.
Just as when you practiced target shooting, check your bow hunting equipment thoroughly, including your broadheads, before taking into the field.
You may feel that learning the basics of shooting your bow will surely lead to instant success. We certainly wish you bow hunting success.
