Many strength athletes who have played with grippers, myself included, have wondered whats the difference between a captain of crush #3 and an HG300. In this post, I am taking aim at discussing the differences that i know of. You asked for it Jared.
First off the springs are wound with a CNC machine but are both from different companies therefore different metal and even vary among the same brand due to different batches of raw material, etc... CoC is usually better at sticking closer to a single strength but they still all vary some.
The winding of the spring has to stop eventually and leaves two ends for mounting the handles on. The distance between these two ends is what determines the final spread which is the distance between the two handle ends. Heres a picture. CoC is on the right and hg300 on the left. You cant see the tips of my hg300 because I filed it for training purposes a long time ago.www.flickr.com/photos/10077623@N06/3587054961/
Obviously the thickness of the spring matters. That is measured with a micrometer. I could only find the CoC spring diameter online and it was .281" Heres a comparison. The Hg300 doesnt look too far behind in spring diameter... if any. again... CoC on right.

Its easy to see the spread on the COC is alot bigger. Not only does it make it more difficult logistically in your hand it also makes the spring coil tighter when you close it and therefore its harder even with the same spring of a different spread. Even spreads differ in the same brand. Usually not by much though.

Another factor is the mounting depth of the spring. That is measured from the bottom of spring coil to the top of handle. If you think of the handles as an extension of the spring then mounting the handles higher up gives you less of a mechanical advantage just because your higher up on the spring. The only grippers i could find with mounting depth info is the gripboard MM cert grippers. but visually you can see the CoC is mounted a bit higher than the HG300.
The company ratings are #300 and #281. This is pounds-per-inch-force or some other shit. The HG is measured in the middle and CoC I dont know. Couldnt find any info on it.
Thats all the variables i can think of on the gripper side. What you should really be worried about though is what you can control like your set.
In my opinion they are both tough grippers but the CoC#3 is alot tougher and if you are closing say an HG300 for 4 reps(off the top of my head) you should definitely skip the coc2.5 and go for a #3.
Now do you see the reason for my MD journal title? btw, ask your website guy to allow use of the {img} function so i can embed pictures please. Im guessing its my low post count. You can trust me Jared.
This is how you do it baby.. stone cold at 11pm.
