How Does Thermal Imaging Scope Work?

Not everyone is cut out to be a daytime hunter. Some of us prefer the night sky looming over us as we set up base and prepare ourselves for thrill of the kill. Or perhaps some of us prefer sleeping in and have no need to wake up early in the morning for a hunt. Then there’s some of us who may not objectively have an issue with hunting during the day…but we can’t for health reasons (think eye sensitivity to the sun’s beams, or perhaps hypersensitive skin).

All of these reasons are perfectly fine; we all comes from different slices of life, after all! But you can’t just automatically leap into the life of night hunting with no clothes on, so to speak. There’s equipment that you’ll need in order to make sure your hunt goes off without a hitch. I’m talking primarily of some kind of tech that allows you to see in the dark, such as a night vision scope or thermal scope. Take a look on these blogs for a comprehensive guide for thermal scope.

If you want my honest opinion, I think you should go for the route of thermal imaging!

Fascinating, What is Thermal Imaging?

Thermal imagery, also known as thermography, is the study of infrared images. It’s similar to a night vision scope, though differs in a few aspects. While night vision collects wandering light particles in the area, thermal imaging collects radiation waves, such as infrared or UV, and wandering heat. And while night vision is mainly used for night time hunting or surveillance, thermography can be used in all sorts of fields, ranging from security, law enforcement, medical, archeological, and more.
Also, hunting.
Lots and lots of hunting.

Niiice, So How Does It Work?

So now that we know the difference between standard night vision and thermal imaging, we should talk about the means in which thermal technology is able to pick up images with such ease, even in the brightest of days. The way this magic comes to life is first through the special lens that is engineered to zone in on infrared radiation. Once the lens picks up on the infrared signal, it’s scanned by the len’s built-in heat detection hardware. Once the scan is complete, it creates a unique pattern known as a thermogram.

The thermogram is essentially the collection of heat data saved by the thermal tech. Once it’s created, its then converted into electrical impulses. Soon after, the impulses are transferred to the signal-processing unit, which is a circuit-board that converts the heat data into pixels which form the final picture. And once that final picture is formed, that’s when we get the famous Predator colors plastered onto our screen. Depending on the colors of the objects, it can determine the intensity rate of the infrared energy (hint, red usually means a high amount).

That’s pretty awesome, isn’t it? What makes thermography so much more interesting is when you think about all the different fields who make use of it. For example, thermal imaging is used in medical practice for the purpose of scanning over areas of the patient’s body. This is done to reveal areas of the body that may be at risk for illness or may already be afflicted with deadly forms of cancer. This is often used in human medicine AND animal medicine.

How awesome is thermal imaging?!

My Guide For Choosing A Quality Rangefinder for Hunting

Whenever I’m looking for a new piece of gear to take hunting u make sure that I’m not wasting money on the item and that I’m not wasting space in pack that can be better utilized by some other piece of equipment. I don’t want my pack to be too heavy but I also don’t want it to have a bunch of stuff in there that never gets used. In short I want to carry with me exactly what I need and nothing more. This obviously gets tricky but I think I do ok when I’m out hunting.

One area that I’ve noticed can really take up a lot of space and not provide a lot of value is the wrong rangefinder. I’m not saying all rangefinders are bad and not worth the money – that’s not true at all.

What I am saying is that if you buy the wrong rangefinder, it will just take up space and weigh you down. I spent a lot of time looking for the best rangefinder for hunting when I was looking for a new rangefinder.

The answer isn’t as cut and dry as I would have liked because there are so many on the market and have so many different features depending on your needs. Maybe focusing on the best rangefinder isn’t as good of an idea as finding the one that best meets your needs.

To do that, we need to sift through all the features that are common on different rangefinders and figure out what ones do meet our needs. First, you need to start with what type of hunting you do most often.

Archery vs Rifle Hunting Rangefinders

One of the biggest differences in terms of rangefinders has to do with the features that the unit come with. There are rangefinders with angle compensation systems (though each manufactured calls them something different). What the angle compensation tools do is help hunters try and determine the actual distance the animal is away from you, while accounting for you being above or below the target.

Example: Lets say you’ve found a group of elk and chased them over a ridge. You move to the top of the ridge and have a peek over, and you can see them about 40 yards down the ridge. If you were to put your bow in and pull back for a 40 yard shot – you’d miss and the arrow would go below your elk, who would then run off. This is because since the animal is at an angle below you, that changes the distance you actually need to be at to hit the elk. Now, an angle compensation tool will help you determine what pin to use in this situation (It should be about a 36 yard pin). That way, you can head back to the truck hauling elk quarters, instead of with a near miss story.

Now, these features aren’t really worthwhile if you dont hunt archery, as you wouldn’t use them much (if at all) if you were rifle hunting. However, they do cost quite a bit and could be a great thing to pass on if you’re not interested in bow hunting.

What Max Range Do You Need?

Another feature that needs to be considered to find the best rangefinder for hunting is the maximum range of the unit. If you typically do most of your hunting from a tree stand, you’re not really going to need a rangefinder with a 1,000 yard + maximum range – you wont be able to see that far through the trees even if the unit you bought had the capability to do so (and even then, you couldn’t be sure you were ranging in your target and not a tree). I haven’t done much hunting in the trees like that, but a friend of mine that took me out had a rangefinder that had a max range around 600 yards, and said that it was more than he would ever need.

I live in the west and hunt a lot in Wyoming, so when I’m out hunting for antelope, there could be a couple hundred yards between me and the antelope when I first see them and when I can actually figure out a way to get on them close enough to get a shot off. A good rangefinder with a maximum distance of 800-900 yards was something that I found a lot of value in when I was looking for a new rangefinder.

Glass

Good glass is what will make or break your rangefinder. Getting good glass with good coatings is crucial to helping you get the best picture you can while ranging in your targets in the field. Good glass will make the picture on your unit clear when you’re ranging in that white tail that’s 440 yards away. A clear picture will do a lot of good in helping you determine what shot you need to take and how to get close enough to take that shot.

As one of the guy from OpticsAddict.com that I’ve hunted with before says “dont skimp on optics – you’ll pay for it in the end”. I agree with him wholeheartedly, and think that you should get the best rangefinder that suits your needs and that you can afford. They are expensive, but they arent worth the constant missing that having a low quality rangefinder could set you up for.

Other Things to Consider

We’ve gone over what we think are some of the more important things to consider when looking for a rangefinder. Those arent the only things that come with a rangefinder, so there are a few more things to consider when getting a new rangefinder.

Magnification Level

Personally, I think 6x a great magnification level and will suit about 90% of hunters. That level of magnification will help you easily see a target clearly at 500+ yards, and will help you get a good eye on the size of the animal as well as the sex of the animal. Keep in mind that a rangefinder doesnt make it easier to range in your target with more magnification – it just makes the target easier to see through the viewing window.

Size, Weight and Hand-Feel

One thing that doesnt often get considered when making a rangefinder purchase is the hand feel. What I’m talking about here is how the unit fits in your hands, and how easily that you can operate the unit with just one hand (as that is what you’ll probably be doing a lot). If the unit is uncomfortable or difficult to operate with just 1 hand, then you probably wont end up using it often as you’ll find that it’s more trouble than it’s worth and stop using it because of that.

While they are minor concerns, size and weight should also be noted. Most rangefinders weigh pretty close to the same amount, with the difference between the lightest one and the heaviest one not being more than 1/2 a pound. Not significant, but still something to consider. Every pound helps when you’re quartering out elk over 3+ miles.

Rangefinders come with a lot of bells and whistles, but typically they arent usually that heavily used when you’re actually out in the field. Get a rangefinder with the highest quality optics you can afford, and you should be fine. If you’re looking for the best, check out this hunting rangefiner reviews from Eric . This is a great suggestion Now, those are just some of the things we look at when we are thinking about the best rangefinder for hunting. What are you looking for in a new rangefinder?

How to Choosing the Best Hunting Rifle?

The starting point for determining the best rifle is to consider the game to be pursued. A rifle for rabbits or coyotes will be very different than a rifle for moose or mountain bighorn sheep. A rifle that is too powerful for a given animal will result in unnecessary recoil and loss of meat. A rifle that is not powerful enough to dispatch the animal quickly in normal hunting conditions and ranges is unethical and often illegal.

Rifle Calibers and What Those Numbers Mean

After deciding on the game to be pursued, the next step is to pick a caliber, which is the approximate diameter of the bullet expressed in inches or millimeters. There are numerous rifle calibers available, from “varmint” calibers like the .17 and .223 used for coyotes and prairie dogs, all the way up to the large rounds used for Africa’s dangerous game, such as the .375 and .458. Among the most popular calibers for whitetail deer are the .308, .270, 7mm and .30.

When there are two numbers in the cartridge name, such as .30-06, only the first number refers to the caliber. The second number can refer to several things. With some, like the .30-06, the second number refers to the year the cartridge was first available – 1906. Sometimes it means a new “wildcat” round was developed using the cartridge from existing round, as in the case of the .25-06 – a .25 caliber round based on the .30-06 cartridge. The second number can also refer to the grains of black powder used in the original round, as in the case of the venerable .30-30.

There can be several different specific types of ammunition for each caliber, and these will generally include the name of the manufacturer that developed them, such as the .300 Winchester Magnum and the .30-06 Springfield.

Choosing the Best Caliber for Shot Distance

Another important consideration in choosing a rifle is the terrain in which it will be used. If most shots will be taken at 100 yards or less, a slug gun or a rifle with a larger, slower bullet such as the .30-30 Winchester or .35 Remington works very well. If the rifle is to be used over longer distances, 200 to 300 yards, then fast, “flat-shooting” rounds such as the .243 Winchester for deer or the .22-250 Remington for varmints are good choices. Cartridges like the .30-06 and .308 are excellent all-purpose rounds for large game.

Other Considerations When Choosing a Rifle

Once a hunter has determined the type of game to be hunted, the appropriate caliber and round, and the typical shooting distance, the rest becomes largely a matter of personal preference.

Bolt action guns are the most popular, but other types such as lever action and pump action have their devotees as well.

A longer, heavier barrel is better for longer shots, whereas a short-barrelled “brush gun” like the .30-30 is great for getting off quick shots in the woods.

Some hunters prefer the look and feel of natural wood stocks, while others prefer synthetics, which are less affected by temperature and humidity.

If the hunter is sensitive to recoil, that should be a consideration when choosing a rifle. Caliber isn’t always an accurate indicator of how much a rifle “kicks”.

Price is often an issue, and there are usually several good choices at each price point.

A good hunting rifle, properly cared-for, will provide years of faithful service and enjoyment. In many cases, they become treasured family heirlooms handed down from generation to generation.
