During a recent discussion on a grip message board, someone stated that the RGC rating system was the best way to rate grippers. I was very quick to disagree. A gripper rating system i created is what i feel is the most accurate and easiest way to rate grippers.
I am reluctant to share this with you as i was with that message board, but due to popular demand and a peaked intrest in this state of the art system, here it is. The DGC.
* Please note, the DGC is still in testing stages and may be tweeked for convenience and accuracy. This is just the rough explination that i explained to the message board.
To start, you will need to take a large metal pole about 12 feet in height and put it about 4 or 5 feet into the ground, the deeper the better. Duct tape the dogleg side of the gripper (you will need a lot of it, almost a roll) to the poll about a foot above the ground.
Now you are going to need a large harness, capable of ensnaring anywhere from 3-12 dogs. Once you have that, go down to the local kennel and tell them you need to borrow some of their dogs. I had to slip the guy a 20 but yours might be more generous. To ensure the most accurate measurements you will need a lot of dogs ranging in weight and size.
Weigh each dog and record the weight and then place them in a large cage with meat hanging above them, just out of their reach.
Now you will need to affix a small rope to the harness and then tie the other end really tight to a strap on the no ductaped side of the gripper. Make sure it lines up with the bottom. By now the dogs will be pretty darn hungry for that meat and you are ready to begin.
You will have to play it by ear with determining how many dogs to start with depending on which gripper you are trying to rate. I found that about 3 medium sized dogs is equivalent to about a trainer, 4 for a number 1, 6 for a number 2 and 9 for a number 3 is a good starting point. Once you determined your base amount of dogs, attach them to the harness and throw the meat so they all chase after it. If the gripper shuts too easily, gather the dogs back and exchange one of them for a smaller dog or remove one completely as needed. If the gripper does not shut you will need to add more dogs. Once you have the gripper to where it just about shuts then add up the weight of the dogs and voila, you have your rating.
On a side note, I found to get more accurate measurements by actually holding on to the dogs for a few days and just giving them water. That way by the time you are ready for testing they will have been starved and want the meat even more. You will have to weigh them right before testing if you so choose this option. Also, instilling fear into their hearts and then scaring them away from the gripper has been known to work wonders for a few buddies of mine, but I myself have never tried it because there is great chance that some of the dogs may turn on you.
Happy rating!
