What is the apparatus you used to test the grippers? Did you assemble this yourself or did you purchase it? I have a lot of grippers I would like to test and this looks like a reasonable way to do it without having to stack loose weights on a strap. The design means it would even work with adjustable grippers, such as the Robert Baraban Adjustable Gripper or David Horne's Vulcan Gripper.
We designed and made the strength meter ourselves. The scale used in the device is a scale that measures the actual weight, and the measurements are very accurate. It is very important to measure the same measurement criteria.
I can close the COC 3 for one rep, which is around 125kg of grip force. When i test my grip strength with handdyanometer, it shows between 105-107kg. How is your testing devices showing 67kg on the COC 3????
Hello, thank you for your comment. The resistance strength of the spring varies depending on which part of the handle is used as the measurement reference point. To compare the strength of the GD IRON GRIP with that of the COC gripper, we measured resistance from the very bottom of the handle. We used this point to ensure consistency in our measurements. In practice, however, when you actually grip it with your hand, you don’t just hold the end of the handle. Measuring from a higher point on the handle more accurately represents the grip strength applied when you hold it naturally. This is why, when you close the COC3, the measured grip strength exceeds 100kg. Please keep in mind that we used the end of the handle as a reference point for consistent comparison.🙂 While the maximum level of the GD IRON GRIP EXT 90 is labeled as 90kg, our tests showed that its resistance strength actually exceeds that of the COC3, which is marked at 125kg. Since each manufacturer has different criteria for indicating spring strength, customers may experience confusion. For this reason, we uploaded this test video.😄
@@GD.Official That would be awesome if you had a website that showed all of your measured readings. Including on your other grippers like the 70 and 80.
An gd iron grip 100 with a rgc rating of 209 lbs at the 100kg setting equal to a coc 4.0 would be sick🔥 Lvl 1 50kg Lvl 2 60kg Lvl 3 70kg Lvl 4 80kg Lvl 5 90kg Lvl 6 100kg 10kg increments would be far better for progressive overload, Level 1 is too much for the most people though to Start with grippers, should warn people Not for beginners
We made this video for those who are curious about the resistance of GD IRON GRIP compared to COC grippers. The resistance guide of COC grippers is much higher than their actual measured resistance, while GD IRON GRIP rates its resistance levels more in line with actual hand strength. Because different grip equipment manufacturers have different strength rating standards, this video was made to demonstrate the approximate differences in real resistance between COC and GD IRON GRIP when measured under the same criteria. If we were to compare based on the guide of COC, GD IRON GRIP's final level should be similar to COC no. 2.(They said the resistance is 195lbs). However, when measuring actual resistance, it can be confirmed that GD IRON GRIP's final level is stronger than COC no. 3. Some customers often ask why the resistance is very different between COC grippers and GD IRON GRIP. Therefore, this video was created to show the strength of GD IRON GRIP at each level and which COC gripper is similar when measured under the same criteria.
@@GD.Officiali have all 3 of the gd iron gripper. Black, red and blue. It would be nice for a test of all them. But my question for this video is why you didn't measure level 5?. Would be nice to know the actual result. Thanks for this video. Keep up the great work :)
You should take measurements from the center of the handle to get more accurate and realistic measurements. Taking measurements from the bottom of the handle will give lower values than those established by the manufacturers. When the hand grips the gripper, the force is distributed near the center of the handle, not from the bottom end.
A better way to rate grippers is to use a certified grip dynamometer to measure a persons max grip strength, then find a gripper said person can just barely close. Repeat. I can just barely, once in a while, close a CoC2.5, and my best grip dynamometer reading is 87.3kg, so I’d rate the gripper around 195lbs. I believe pulling on the end of the handle of a 3 gave a reading of 68kg? That number is not realistic, in that the only way to measure grip strength is with a dynamometer. Other than for comparing grippers relative strength to each other, is there any useful comparison for pulling just on the end of the handle.
It depends how far down the handle you measure. Some measure the force from the center of the handle as your strongest fingers are actually the furthest from the end where the weakest finger is, the pinky. The further away from the fulcrum you apply the force the more leverage you get, but when our hand crushes a gripper all our strength is not concentrated exclusively on the ends of the handles.
Ya measuring from the ends is how you can accurately get a reading as all grippers obvi have an end to the handle yet not all have the halfway mark. Plus it's quicker and easier haha. Each gripper even from the same manufacturer will vary even up to 20lbs or more so it's a good way of telling how strong you actually are and what your really closing. I rate all of mine. I like these adjustable ones because it doesn't affect the left hand since it's a linear spring and the handles are as well. Normal gripper springs are made to be closed right-handed and always with one side of the spring towards your arm (the dog leg). So when you close it left handed the way it was intended to be closed it's more awkward and you can't close as much normally.
Hello! I'm sorry for the high price in India. We have to pay for very high tax and customs duty when we export our products from Korea to India. That's why we the price is higher than the US. I hope you can understand. 😥
@@GD.OfficialI understood but by God the price is almost double for so long I wanted to buy 1 myself but now maybe if someone gifts 1 hahah thanks for the reply
that is for sure not correct lol coc 3,5 is not 90kg more like 100-110kg..and coc 3 around 90-95kg real weight cause on dynometers i can squeze around 100-110kg and strugle to close coc 3.5
Check out the GD IRON GRIP 90, even stronger than the CoC No.3! 💪

This video sold me the GD IRON 90. Now I am waiting to receive it from amazon!
Thank you for your comment! :) I hope you will like GD IRON GRIP!
Those are some hard as grippers, a 96 1.5 coc is crazy
I was able to close it my self at 45 years old.... But I know a 17 years old boy who can close no. 2 ! Unbelievably strong for such a young guy.
That's what I was thinking. Usually they're around 85-90lbs

Please make a 120kg - 180kg gripper. Thank you for your amazing product. :)
Nice measurement device!
I'd say the numbers are probably off. In come cases by 10-20lb. But it's pretty consistent and pretty cool that theres an all in one like that.
Kindly compare with USI hand grippers also
Thank you for this video. Do you have a PDF reference for all COC and GD gripper we can see?
I think that's a good idea. We will measure the resistances of grippers later so that other products can be compared.😀

Why Capitan of crush is fake weight?
afaik they measure in the middle of the gripp so it's not fake
@@quisazaderak9257okay that make sense
This measurement is wrong. You don't press it from the end of the handler, but somewhere in the middle.
You have no idea what you're talking about.
@@TheStrengthScholar
Yeah? So what idea do you have? Where do you press your own expander?

ok now try to close them closer to the spring. the poundage will increase.

multiply1.5=real grip strength，Because the position held by the hand is further up
You should take measurements from the center of the handle to get more accurate and realistic measurements.

Dude doesn't know how grippers are rated lmao
strangely the account is from the manufacturer

Yeah they also send me a Bar extender when I ordered the I.G. 90. Haven't used it much though since I'm trying to maxout I.G. 80
74 dollars i buy 8 grippers
