A Classic or an outdated relic? | NAP Thunderhead Broadheads Review

In this review, I tested a classic broadhead… the NAP Thunderhead!

These heads have been around for a long time. I actually like testing these older broadheads like this one, just to see if the newer designs have passed them by or if they really are still holding their own.

For these tests, I used my Bowtech SR6 set at 72 pounds, 27” draw. I’m using Bishop FOC King Arrows for most of the shots, but then the Bishop FAD Eliminators for the really hard impact ones.

So, let’s go through some of the design features and specifications and then put them to the test!

The NAP Thunderhead At First Glance

Let’s zoom in and check out the Thunderhead and then put it to the test.

nap thunderhead length

Here’s a good look at the 125-grain Thunderhead. It’s a petty cool, classic design. It has a cutting diameter of 1-3/16”. It has an overall length beyond the ferrule of 2”, so it’s pretty long by some of today’s fixed-blade standards, especially for 3-blade heads.

thunderhead blade thickness

It has steel blades that are 0.027” thick, which are pretty thin by today’s market standards.

thunderhead chisel tip

The tip is a hardened steel, chiseled tip that’s really pointy. I really like this chiseled tip. The ferrule is made out of aluminum.

thunderhead ferrule grooves

Notice that the ferrule of the Thunderhead has micro-groove channels in it.

The micro grooves in the ferrule are supposed to aid in flight as it carries the air around with it and it rotates, which is supposed to aid in penetration. This is similar to what the dimples on a golf ball do.

Thunderhead Testing

So, I was really eager to put the Thunderhead to test and see how it would hold up, especially since it has been around so long and has such a loyal following. Let’s see how it did!

Flight Forgiveness Test

In the flight forgiveness test, I shot one filed point and then two broadheads into the target at 40 yards.

Initial Sharpness: 225

thunderhead initial sharpness test

To test the “out-of-the-box” sharpness of the Thunderhead, I tested how much pressure it would take for the blade to cut through a metal wire (the lower the number, the sharper it is). It registered 225.

Penetration Test #1

thunderhead ballistic gel test

I shot the Thunderhead into a block of ballistic gel that was fronted with a 2/3″ rubber mat and 1/2″ MDF. It penetrated 6-1/4″.

Edge Retention Test

Thunderhead sharpness test #2

After Penetration Test #1, the sharpness scale registered the Thunderhead’s sharpness at 325.


Penetration Test 2 (layered cardboard):

The NAP Thunderhead penetrated through 59 layers of cardboard.

Angled Shot Test (1/4” MDF/Carpet)

thunderhead angled shot

I shot the Thunderhead into angled MDF fronted with carpet.

Durability Test #1 (1/2” MDF max 3 shots)

I also shot the head into 1/2″ MDF (3 shots).

Durability Test #2 (Steel Plate)

thunderhead steel plate test result

In this durability test, I shot the Thunderhead into a .22 ga steel plate (max 2 shots) to see how it would hold up.Here’s the head after going through the steel plate two times.

The Thunderhead looked brand new after going through the MDF and the steel plate and it still held up really well. But, the blades got a bit nicked up (“edge chatter”).

And then you can see the hole. You can see how it looks like just a ferrule hole with 3 slits coming off of it.

Durability Test (Concrete)

I shot the Thunderhead into a concrete block to see how it would hold up. The tip embedded really deeply into the concrete and I couldn’t get it out. I didn’t want to mess up my concrete by digging it out. And, this one blade got stuck right in the end into the concrete as well.


thunderhead after concrete test

Here’s the Thunderhead after being shot into the concrete. As you can see, the ferrule just broke off right there. The other two blades just stayed intact. They got a little bit nicked up there at the end but they still stayed in place.

And overall, after the concrete block test, it still spun decently, but it did just break in half. Now, that’s after going through the MDF 3 times and the steel plate twice. So overall, fairly impressive durability.

Final thoughts on the NAP Thunderhead

So what do you think of the Thunderhead?

When my buddy told me he was going to send me a pack of these, I was intrigued. I like to test every head. But, at the same time, I thought, “They are so old school. The newer stuff is going to be blowing it away.”


But, then when I started playing around with them and looking at them, I thought, “No, these are really well-made and well-constructed and designed.”

And the tests just proved just that. I can see why they have such a loyal following and why they’ve taken so many animals over the years.

Now, I will say that I think there are other 3-bladed heads on the market that do better than this one. But then again, this is better than a lot of them that are on the market as well.

So check out the score sheet in the description box and see how it performed in the areas that matter to you the most and see if it might be a good fit for you.

buzz centris folding e-bike

What’s All The Buzz about? [BUZZ Centris Folding E-Bike Review]

Looking for a fat tire e-bike to do some off-road riding?

And how about one that folds up as well? [Bonus!]

Well, in that case, let’s take a look at the Buzz Centris FAT Tire E-Bike!

The Buzz Centris fat-tire folding e-bike

This Buzz Centris model launched in January 2022 and is the newest edition of Buzz’s FAT e-bikes. But, before we dive into all the features of the Buzz Centris, let’s tell you a little bit about Buzz…

About Buzz Bicycles

The Buzz Bikes team believes that the freedom of riding should be fun and accessible for riders of all skill levels, regardless of what outdoor adventure you may be on, so that you can “buzz” through life!

buzz bikes ohio

Buzz e-bikes are designed in Dayton, Ohio by passionate team of bike enthusiasts who have a goal of delivering ultimate transportation solutions at a great value.

The unboxing of the Buzz Centris Folding E-Bike

Right out of the box, one of the positive features of the Buzz Centris is how easy it is to put together.

Buzz Centris folded up 1

So, here is a look at the Buzz Centris in its folded position. And, this is really pretty much what it looked like right out of the box, less the foam padding and packaging that we removed.

Once we took it out of the box and took the safety packaging/padding off, it literally took less than 60 seconds to put the whole bike together and have ride ready.

buzz centris folded up 2

The Centris folds up nicely, making it much more compact. so, if you’re going to put it in the back of a truck, inside a vehicle or an RV, it definitely makes storage a lot easier.

Now, the Centris does weigh 67 pounds, so it’s not exactly light. But, because it folds up so well, you can store in some tighter spaces and take it with you if you’re going to be on the road.

The Centris was super simple to assemble. We didn’t even have to really look at the manual very long to figure any of that out.

Key Features Of The Centris

So, let’s take a look at the key features of the Buzz Centris…

Tires, suspension, motor and brakes

The tires of the Centris are fat (4 inches fat, to be exact!).

buzz centris 4-inch tires

The Centris has 4″ wide tires, which are great for trail riding and on various types of surfaces.

The Centris also has front fork suspension which aims to be helpful when riding in off-road situations and more rugged terrain than your typical road ride. It’s even a great option for if you’re hunting on public lands where gas-powered vehicles are not allowed.

buzz centris front fork suspension

The front fork suspension gives extra shock absorbency to off-road terrains.

It has a 16” step-over height. It sports a 500-watt peak level rear hub motor.

Here’s a look at the rear hub motor of the the Centris.

It has 5 levels of power assist and a 6-speed Shimano Tourney Derailleur that provides precision shifting.

Here’s a look at the handle bar gear shifter.

Here’s a look at the Shimano Tourney Derailleur.

disc brakes on buzz centris

The Centris has front and rear disc brakes.


The Centris has a thumb throttle for non-pedaling power. So, if you decide you need a breather during your ride, you can use the thumb throttle and it will take over and you will be riding all-electric.

buzz centris thumb throttle

Once pedaling has begun, the thumb throttle can be engaged and the bike will run strictly off electric power (no pedaling!)

Buzz claims that the Centris can reach speeds of up to 20 miles per hour when not pedaling.

Now, you should take into account that the 20 MPH number is assuming a flat riding surface and also depends on the terrain you are riding (smooth, rough, etc) as well as the weight of the rider. (We’ll provide the results of our findings in this area a little later on in this review).

Front basket rack…

It also has front and rear racks for carrying things… like maybe a big buck or a big bass! (Well, maybe not, but you could carry a duffle bag or a backpack or utility pack in the basket!)

… and the rear rackk.

The Centris also has an LCD screen that displays your speed, battery life, and the electronic pedal assist level.

buzz centris electronic controller

The controller shows the speed assist level as well as the current battery charge, mph and odometer readings.

It also has an adjustable seat height.

buzz centris adjustable seat

The seat of the Centris has multiple adjustments.

It’s got a removable lock-in battery with battery cover, and inside is a 48-volt rechargeable battery, that according to Buzz, will give you up to 40 miles per charge and recharge within 2-6 hours.

Again, you want to keep in mind that these are estimates and they are going to be based on things like rider weight and also the type of terrain that you’re riding on.

The Centris’ battery is 48-volts and locks in place.

Another neat feature is that is also has a headlight.

The headlight is easily assembled and is controlled by the LCD screen display buttons.

Warranty of the Buzz Centris

The Buzz Centris sports a 2-year limited warranty on the electronics and it has a 10-year warranty on the aluminum frame. And, the Centris is UL-tested.

buzz centris bell

And one very, very important feature… a powerful little bell (OK, so we’re not huge fans of the bell, but it is mandatory in some states.)

You can get the Buzz Centris fat-rie E-Bike, with all its features, for $1199, which includes free shipping to your doorstep!

Test Ride

We got the Centris charged up and ready to go. Then, it was time for the fun part… we took it for a spin!

What we learned

After a 3-mile test ride we can tell you… the Buzz Centris is a ton of fun!

We rode it on a flat surface to test the speed and then went straight into the woods and rode trails that had both inclines and declines.

buzz centris riding on the road

The Buzz Centris, with a 180-lb rider, reached a top-speed of 20.1 mph while using only the controller (no pedaling).

Over the course of the 3-mile ride, the battery stayed on the fully charged indicator! So, the battery life seems to do very well.

riding buzz centris in the woods

We rode the Centris off-road through wooded trails and it did well.

We also did a speed test on the road to see if it would in fact go 20 miles per hour, as the specs stated.

It actually reached a top speed of 20.1 miles per hour, using only the all-electric thumb throttle (no pedaling)! So, the top speed of 20 mph is as advertised!


The one thing that we’d like to see improved would be the suspension. During the off-road trail riding, the suspension bottomed out pretty hard a few times as I went over some rougher parts of the trail.

Final Thoughts on the Buzz Centris

All in all, the Buzz Centris is a great ride. And man, what a ton of fun!

And, it was actually pretty actually quiet. The motor does make just a little bit of noise, but nothing real significant.

So, if you’re looking for an electric folding bicycle to enjoy in the woods and on off-road trails, this is a great option for the money!

We are excited to get to do some more testing of the Buzz Centris fat tire electric bike. We hope you enjoyed the review. Ride safely!

black widow arachnid broadhead review

Arachnid Broadheads Review [6-blades?!] | In-Depth Analysis

In this review I tested the Arachnid broadhead from Black Widow Innovations.

Now, this is a really cool head!

So, let’s check out this Arachnid and then put it to the test.

I’m using Bowtech SR6 set at 72 pounds and I’m using Bishop FOC King Arrows for most of the tests. But, on the really hard impacts tests, I’m using the Bishop FAD Eliminator.

A close look at the Arachnid Broadhead from Black Widow Innovations

Below is a good look at the Arachnid. Now, it doesn’t make a really wide hole but I imagine it’s going to cut a lot of tissue and open up that 1″ hole fairly well in an animal.

black widow innovations arachnid

This is a cool-looking head and it has got some really unique features. First of all, it’s 6 blades with a 1-inch cutting diameter, giving you a total cut of 3 inches. The blades are made out of stainless steel.

arachnid broadhead tip

The tip is made out of A2 steel, which is much more resistant to impact than typical stainless steel, about double the resistance to impact. So that’s going to make that tip extra durable and strong.

Now, another neat thing about the Arachnid heads is that they come with 3 extra beefy chiseled tips that are made of A2 Tool Steel, just like the blades.

And they are really big!

arachnid broadhead extra tip

The Arachnid comes with three heavier tips made of A2 tool steel. With these you can up the weight from 100 to 125 grains.

So, you can either shoot it in a 100-grain or in the 125-grain, just by unscrewing and screwing in the other beefy, chiseled tip.

So, I like that modularity, and I like that 125-grain head makes up that weight not just by adding a heavier washer, which really doesn’t do anything to strengthen the head or make it fly better.

But, by adding an extra beefy tip, you’re making that head a lot more durable.

Also, you’re putting that weight all the way at the front which is going to increase your front of center just a little bit as opposed to putting the heavier washer back here.

The blades are relatively thin at 0.027″ thick. That’s probably due to having 6-blades and being able to make the weight.

black widow arachnid single bevel blades

The blades are also single bevel, on the front and the back of the head, which is really interesting. It’s probably done so that they don’t get too narrow, too thin. If they were double bevel at 0.027″ thick, they might be too thin.

Because the blades are sharpened on the back as well, if you are pulling out of a target, that will make it a little easier. And, if it’s backing out of an animal, it will be cutting tissue while it backs out of an animal.

arachnid broadhead ferrule

The ferrule is made out of 7075 aluminum, so it’s a pretty short ferrule and it’s a pretty stout aluminum. So, I thought the durability would be relatively good.

Now, one thing I will say is, when you’re putting the head together or when you unscrew it from your arrow, those blades can fall out really easily; a lot more easily than a lot of different designs.

And so, you have to be extra careful. They come with bases that you can screw on when they’re not in the end of your shaft just to keep the blades in place.

And, you really want to use those because it is pretty frustrating trying to get them all lined up and get them snagged on your arrow.

Black Widow Arachnid testing

I was really eager to put it them to the test and see how they performed.

Flight Forgiveness Test

I tested the Arachnid to see how the heads flew vs. a field point.

Initial Sharpness Test

The initial sharpness test result of the Arachnid was 150 on the Sharp electronic tester.

Penetration Test 1 (2/3″ rubber mat, 1/2″ MDF, FBI Gel)

arachnid ballistic gel test

The Arachnid penetrated into the rubber mat/MDF/ballistic gel 6-7/8″.

Edge Retention Test (sharpness after Penetration Test 1)

arachnid sharpness after first test

After the first penetration test, I re-tested the sharpness… 225.

Penetration Test 2 (layered cardboard)

The Arachnid penetrated through 57 layers of cardboard.

Angled Shot Test (1/4” MDF/Carpet)

Here’s a look at the angle shot test setup.

Durability Test (1/2″ MDF max shots)

arachnid after 3 shots through MDF

The head was in perfect condition after the angled shot test and 3 shots through the MDF. Now, it’s on to the steel plate test…

Durability (22 ga steel plate max 2 shots)

Here’s the head after 2 shots through a .22 gauge steel plate.

arachnid broadhead after 3 shots into steel plate

It held all of its blades perfectly. None were lost. None were bent. The edges did get pretty mangled up as you can see. And, the tip got a little bit blunted. But again, they all held in place and they made really nice holes in the steel plate (that’s pretty cool hole with those 6 blades and a really round circular hole in the center!)

Concrete Test

In the final test, I shot the Arachnid into a concrete block. Below is the Arachnid after that test.

Now, at this point, it had already gone through the MDF 3 times and the 22 gauge steel plate twice. There was a bit of a wobble to it after the concrete test. The ferrule also got a little bit bent.

But, other than that, man, it held together very well in this zero penetration test.

Finally, I shot the head into a concrete block…. The tips got bent somewhat and it had a slight wobble in the spin test.

Final thoughts on the Arachnid Broadheads

So, that what do you think of the Arachnid?

Man, I have to say that it performed a lot better than I was expecting it to.

lusk archery grade of the black widow arachnid

I didn’t think it would fly as well as it did or penetrated as deeply as it did or be as durable as it was. So, I was pretty impressed with it here.

Be sure to check out the total cumulative score and the corresponding Lusk grade! Happy bowhunting everyone!
