Criteria Used for Evaluation

Ease of Use

Even the most experienced hunter may not be able to masker elk calling which makes it important for them to use a product that will complement their work in the field. Some devices have been simplified to enhance performance. One such upgrade is the use of a press button product as opposed to a wind device. This ensures that you get a clean, clear and accurate sound every time. With mechanics that allow you to adjust the pitch and sound type, even a novice can hunt like a professional and achieve excellent results.

Wind instruments such as bugles require a level of skill and knowledge as well as interaction. This means that a hunter will have to alternate between calling and hunting in order to achieve the required result. For this reason, many brands have opted to go for a smaller design that will offer users a hands-free option. This not only increases maneuverability but also efficiency. Your ability to act quickly can be the difference between success and failure out in the field which makes a hands-free option quite valuable.

Many brands have sought to widen the mouth opening on their product to increase performance. This adjustment increases airflow which makes it easier for users to get the right tone and pitch. It also enables them to hold a note without becoming winded as a small mouth opening requires increased force to produce the desired result. It will also make it easier to move through the entire range of your device including the higher octaves.

Adjustability

Products that are constructed with a press button feature may seem simple, but they provide users with a wide range of options due to their adjustability. By turning the bellow button you can cycle through a number of different sounds. Each signifies something different to an elk and selecting the right one can provide a high success rate. You can also use the button to adjust the pitch of the sound. This gives the illusion of being closer or further away. With the sets generally available herd talk can also be simulated.

A bugle is a must have when it comes to hunting equipment and while some a specifically designed for diaphragm instruments, others can use a wider range of pieces. Adjusting the attachment used on your bugle can have a significant impact on hunting results. This is especially the case when it comes to your maneuverability as a tone top and a palate plate fit differently in your mouth and may affect how well you can get the sound you want. It is always best to try both so you can see which works best for you under various circumstances.

When it comes to bugles, the length and construction play a large role in sound quality. It is also a deciding factor when it comes to the range of sound you are able to produce and maintain when out in the field. The design dictates the back pressure that you get when trying to create sound. Some designs have a tapered venturi design which makes it easier to get the sound out clearly with a minimal amount of effort. You are also able to hold notes for longer periods of time without becoming winded.

Features

Some designs are constructed to be 100% freeze proof which ensures that your device works well even in cold conditions. These products function based on air flow and if your device begins to ice up it can have an effect on the sound produced. It can also create a challenge to use as more force will need to be applied to get any sound out. These heavy-duty designs are ideal for users who operate in extreme conditions. It also works well when used at night as this is when temperatures tend to drop to its lowest point.

If you are using a design such a bugle there are a number of benefits one of which is that some manufacturers make parts such as the grunt and baffle removable. The baffle regulates the air and the grunt helps to produce the sound. When these are damaged it can be difficult and close to impossible to operate your device. Being able to remove and change these parts with ease adds a layer of convenience when operating in the field.

There are some brands that offer a four piece set that is not only color coded but a combination of various designs that can be used to create a vast range of sounds. The more versatile your arsenal when out in the field the easier it is to adapt to any situation that may arise and the higher your chances of success. Each unit has a predefined range of sounds and can be used as a pair with another item in the kit to simulate herd talk.

Accuracy

The baffle can be used to lower the pitch when using a bugle. This strategy works great for close in calling. Some manufacturers have made their bugle multi-purpose with removable parts. This allows users to adjust the parts on their product based on the circumstances they encounter in the field. By removing the baffle your bugle can be used for a wider range of sounds providing a wider range of communication when calling to an elk.

There are brands that have increased the number of parts used within their products to give users more control, accuracy, and variety when using their products. For example, there are some devices that utilize over 10 moving parts. This increases the range on the product allowing consumers to get to higher notes with greater ease and less effort. It also ensures that they don’t go past the tone that is required for a particular type of sound.

Many brands offer designs that can simulate cow, calf and bull sounds. With four piece sets, however, you get a better-combined range of sound that leaves you with more in your arsenal when out in the field. Since your utility is spread over four separate devices, these are able to tune in more specifically to breeds within a species. For example, there are four piece sets that can be tuned to deliver accurate sounds for up to four different types of bull including spike and satellite.

Materials

Aluminum is used to make the frame of some diaphragms which gives the product a number of valuable properties. This material is strong and resistant to rust and similar forms of degradation. The longevity of this product is therefore prolonged and it also offers users increased durability. When it comes to sound, this metal is an ideal choice as it makes it easy to tune the device which provides a wide range of sounds when utilized out in the field.

When metals are used to form the frames of diaphragms, they can be quite hard to the touch during use which makes it rather uncomfortable. It also affects your ability to use the product effectively which is why many of them are covered in rubber. This material is strong and highly resistant to environmental damage which is ideal for consumers who operate in fields under extreme conditions such as rain. In colder temperatures this coating protects your device and prevents it from freezing up, keeping the sound quality consistent.

Latex is used to create variations in tone when in the field. In order to be effective pressure needs to be applied to the latex. This feature is present on most bugles and some of them may allow a user to manually adjust the pressure that is applied to the latex. Some tubes are designed to be used with diaphragms. This adds an extra layer of sound to your bugle and can increase its authenticity. This combination is commonly used in cow calls.

Style Concerns

The palate of some of these products is placed in a more forward position, right behind the teeth. This provides users with a higher measure of control and prevents them from gagging on the device. Since the force is being used to create the sound is less, consumers have more versatility and maneuverability when using the product. This gives them the advantage of getting more sounds out that are authentic and clear without getting winded or having the device stick.

Practice Makes Perfect

Cow and calf mews are by far the most common and more essential type to master as they are the most regularly heard sound out in the field. By mastering this sound and knowing when and how to use it you can have a great deal of success, especially if you are hunting in the woods.

Take Time to Educate Yourself

The elk is one of the most vocal creatures, especially when you compare them to deer or moose. So when it comes time to attract them, you should first try to educate yourself on the different types of sounds that elk can make and what each individual noise means. This might require some dedication on your part, but it will only pay off for you in the long-run when you are better able to understand the creature you are hunting. Chirps, mews, bugles, and barks are all very different sounds that elk can make and can mean the difference between elk-to-elk water cooler talk or one elk alerting others than danger (a hunter) is nearby.

Other Factors to Consider

Accessories

This type of product does not generally come with accessories; however, when sold in sets and combos, there is a lot that can be obtained in your product kit. Four piece diaphragm sets, for example, are generally shipped with convenient cases that can be used to store your device before and after use. It can also be carried on trips, however, depending on the size of the case, it can be a challenge these cases tend to be made out of hard plastic. When the metal structure of the diaphragms knock against the sides of the case, the sound can scare away elks in the vicinity or even give away your position.

When acquiring a bugle, it can be noted that they may at times arrive with a lanyard. This accessory is designed to attach to your device allowing you to hang it around your shoulders or in another convenient plays for quick and easy access. When operating in the woods your ability to move quickly can mean the difference between success and failure.

Other great accessories include instruction videos that may be offered along with your purchase. These contain vital information such as the type you will have and the details of how to create and perfect each one. This is a great feature for Advanced as well as novice users.

Use

Based on the type of device you acquire basic calls such as mews can be created. Ranges typically cover cow, calf and bull. If you acquire a bugle or diaphragm you can increase the variety of sounds you are able to produce which can make your trip even more successful. When used in unison or combined with similar products a user can simulate herd talk. The pitch of a sound can be tuned for close calling and some brands can even provide a distinction of sound between to breed of the same species.

Frequently Asked Questions

q: Does size matter?
a:

Yes, in every regard. The size of your diaphragm for instance has a direct impact on your ability to vary sounds. If your device is too small, it will not fit into your mouth properly which can present a challenge when it comes to maneuvering to achieve a desired tone or pitch. If it is too big and not properly positioned it can cause you to gag making your sounds inconsistent.

q: What are the benefits of having removable parts on your bugle?
a:

The bugle is ideally designed to create bull sounds. Removing some parts and replacing it with others can help to refine or amplify the sounds created using the diaphragm. Planning ahead for the combinations you will use while out in the field can help you to get the most out of your device.

q: Can all be used with a bugle?
a:

No, they cannot. Elk calls such as diaphragms are designed to be used with products such as the bugle, however, reel calls and other similar designs are not suitable for a bugle, but they carry a wide range of tones and pitch. Both these facets can be tuned and enhanced, however, they cannot be attached to the mouthpiece of a bugle.
