Chronograph Testing the 85# Biocomposite Turkish Grozer Bow 

That horn layer on the belly side looks sooo nice 😲

Also do you know why you can't shoot straight? Because you're not strong enough, or conditioned for that weight and you are going to blow out your shoulders. If you keep shooting arrows to light for your bow your either going to have your bow explode from violent delamination or the arrow will snap on release from paradox and drive the back half of that arrow right through your bow hand . Don't say I didn't tell you so .

80 pounds is way to much for you? You'll get permanent injuries if you continue like that. The pain in your shoulder should be an indicator. Lower your left shoulder down. And the pain in your right arm just means you're not pulling with your back enough. And don't do these experiments with light arrows. That's war bow poundage. You'll destroy the bow with light arrows, and you run the risk of braking the arrow and having it go through your hand upon release.

Hi Tim, thanks for keeping these videos around, they are very helpful. I am kind of surprised with the performance though. Just this past weekend I chronographed my Great Plains recurve, which is 60 lbs at 28" draw length measured 199 fps. A C shaped reflex bow 85 lbs should be measuring way above 220 fps (at 28" draw length)

You gotta use both hands equally... Many warnings about long term injury from imbalance in old archery traditions. Ottoman style was you pull the bow 600 times on each side before you get to use arrows... always practice equally with both hands according to that tradition... Why not? it is fun, easy to be equally good on both sides, especially if you do it from the start. You will be able to have more fun because of less aches...

Nice results! I think the errors might be occurring because you don't have the plastic diffusers on top of the wires. They're meant to be used on a sunny days when there's too much sun light.

Nice shooting there. That bow is FAST! But I suspect you may not be drawing it to a full 28". You can check by marking the arrow at 28" and get someone to see if the mark gets drawn to the back of the riser. You will be surprised how much our body tissue gets compressed drawing a heavy bow. My draw was 28 with a 30# bow but only 27" with a 45# bow and I suspect even less with a heavier bow. Also your arrows are under spined from the angle they stick into the target. That tends to rob energy from the shot and could be dangerous especially with such a heavy bow.

Tim, I don't believe draw weight directly correlates with arrow speed. Heavy draw weight Asiatic Style Bows are generally used to propel heavy arrows...allowing for higher kinetic foot pounds of energy to more easily penetrate armor. Arrow speed is more directly related to the efficient transfer of energy (stored in the flexed limbs) to the arrow. You can even reference Grozer's website and see that he displays some older speed records for a few of his bows...they have far lower draw weights. IE: Laminated Turkish bow @ 45# with 226 fps, An Assyrian Biocomposite @ 56# & 237 fps and another Assyrian Biocomposite @ 61# & 243 fps! For most circumstances that require effective and efficient killing (hunting for example) the draw weight of the bow is less important than accurate shot placement. (Certainly accuracy is better achieved at a draw weight which the archer can easily hold for 10 seconds) Most US states have a minimum draw weight required to hunt large game. (Deer, Elk, Moose and Bear) For example, Colorado requires a minimum of 35 # Draw Weight. This bow is out of your effective draw weight range capability. Propelling those light weight arrows will cause damage to the bow. Even Grozer will cancel any expressed or implied warranty, if the archer uses arrows below a specific number of grains per inch...as it is similar to dry firing the bow. This is not a Flight Bow.... As well, even real Flight Bows have a considerably shorter lifespan, because of the intensity of stresses inflicted on them. Just my thoughts. Grozer sure does make beautiful bows. 🙂🏹👍

Grozer Biocomposite Turkish short bow is 375 Euro plus 30 Euro delivery directly from Grozer, Hungary. Longer Turkish Bio bow is 405 Euro plus delivery.

I could not find the Turkish bow on eBay, can you tell me what you searched, thanks. +Tim Piatek

That thing is pretty quick! I would bet it could reach comparable speeds to what you were saying Grozer himself achieved. I think it will be easier when your muscles stop being so sore. Now if someone can just get a PVC bow to shoot that fast!

You can clearly see how much of a deadly weapon a bow can be by just looking at these arrow zip through the air at such amazing speed. An arrow would probably pass through a man at 20 meters shot out of this bow

speed of arrow is measured before hitting the target at the distance that is used average 22 m, hunting and battle writes in 7000 written data and sources, and the rest are stories and lies on the measurement of forces other time

that bow is amazing!

Thanks Tim! I feel like your fastest shots did not get recorded, you probably hit 222~ there . Iv'e made a bunch of sinew backed bows but never tested the speed. These chronos seem whack, is there a more reliable way to record arrow velocity? Also please post a link to the bow.

How would you string that bow? I'm a complete beginner but really want that Turkish bow!

but respect for you thats u keep live the tradiition

Are you pushing those shoulder blades together? It help a lot with heavy bows

I think you would have been happier with the results if you had used a thumbring releasee from the right side of the bow....

I saw 134lb Turkish bow it shoots 653 meters

Thanks for your hard work. How does it feel compared to an PVC of about the same shape?

What is the weight of the arrow?

speed of arrow is measured before hitting the target

I’m surprised a fiberglass bow of that weight and design shoots that slow. I’ve seen primitive wood bows that shoot the same speed. Something is not right and you should get your money back.

wonder how this would go with my 32'' draw.

your pulling technique is wrong. a Turkish bow is pulls with a zihgir

Dobar video.

Where did you get the bow and how much do they run?

do you still make bows

excellent! I want to get good at horsebow to go hunting.

Wow very ligth arrow, wich is the minimun gpp on this biocomposite bows??

why you don't make Videos anymore??

I wonder, did you test the bow later on after this?

alive..

60 ponuds are enough for 240 feet/sec why do you suffer with a 85 lbs bow???

Hello tim. Did you do speed test to mehmet golhans sipahi

Are you up to selling that beautiful bow yet?

Thumb ring bro, it’s traditional

where in the world did you find a 85# turkish bow?

Grozer bow it is made in Hungary!

Hi Tim!nice bow and nice shooting.Look at my friend Peter Bogar s Bogar Archery videos.Rob.

Turkish bow is small but very strong

this is Turk bow need thumb ring.

You can shoot better using a thumb-draw if you are shooting with a turkic bow.

85# !!! give your self a break superman .

it is nat real bio composite it is centetic with epoxy with sinew :)

thanks

Why would you ever need a 85# pull? Unless a bow is so poorly designed that you need such a hard pull to give enough speed. 60# in a well designed traditional bow will take down any big game on the planet.

can i buy this bow from you

Why would you want to torture yourself with an 85lb draw!? wouldn't it be much more comfortable and fun with a much lower draw weight?

My 50# norka bow shoot faster than a 85# biokompositbow

-62 lb Longbow shoots 200 ft per second

thumb release god dammit!

get a normal chronograph.. this one is crap for sure!
