Scott I've been using a 1202 because it allows me to compare the stim levels on two collars just by flicking the toggle switch. It eliminates variances between two separate systems. I have a 200 but I don't have a dog that's so sensitive to the stim that he feels the charging pulse. I don't think that the Al Ruf modification will work with the grid because there's no way to mount the diode and the resistor between the contact points any more.

BTW it's not a reliability problem it's a problem because of the way that the circuitry is designed. At very low levels of stim the collar sends a "charging pulse" between the contact points. If you have a dog that feels the stim at less than a 10 on the dial, the charging pulse is actually higher than the 10 setting. Very few dogs, probably less than 2%, are that sensitive.

Lou,
I understand the reason for the low-level issue with the 200 and its charging pulse...sorry that I used the term 'unreliable', just didn't want to get into all of the electronics here....

I personally don't have a dog that is supersensitive to the stim with the 200 (below 10), but I use my collars on a BUNCH of different doggies. I never did Al's mod because most of my own dogs work just fine around 20.

I am just concerned because you stated that the SCG requires one to use a lower level of stim than is required with the standard electrodes, and wondered if using the SCG on a 200 would put the required stim level down into the range of the charging pulse.

Guess there's only one way to find out <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

The SCG looks and sounds like an idea whose time has come, and I can't wait to try it out.

What about the ability of this to withstand complete submersion in H2O , mud, or take direct impacts ? Any tests on that yet Lou ?

Scott,

I ordered the Grid and it should be in within the next few days. I have a Dogtra 200 NCP Gold and my dog is fairly sensitive to the stim. I typically leave it around 20 but I have lowered it to 10 or so and he still reacts to it (when he is very calm)...albeit not much at all, but it does seem that he feels it. But in his normal daily behavior, I have to put it about 20 to get a reaction and I need to leave the collar on pretty much all day so I thought the grid would be perfect.

I will let you know how he does with it...

Marc

Brad I haven't seen any difference in total immersion in water. I haven't done anything with mud. I've dropped the receiver several times on hard surfaces but it's landed on the box, not on the grid. If it landed grid-side-down the strap would cushion the blow.

The grids aren't perfect. I've been leaving them on my dog for the same amount of time that I used to leave them on (just about all day) but not moving them several times a day as I used to with the contact points. Twice I've discovered the red marks that signal the start of sores on my dog's neck. This dog, a GSD, has very thick fur, that under certain conditions mats down. On one occasion the grid had neatly parted the hair and was resting directly against his skin. Since the center "contact point" of the grid is a little taller than the rest and mine had a slight burr on it, it caused quite a bit of redness. I've since filed that center "contact point" smooth but you might check yours.

While the contact points may have done this same thing, I'd guess that because of the fact that I wasn't moving the collar around, it probably exacerbated the problem.

Does anyone who has this grid contact device know why the center contact in concaved? It makes no sense to me. The center point is actually sharp in relation to all the surrounding points.

I received my grid on Monday and put it on my 1100NC for training the next morning. So far it is a great investment. My dog gets a “18” stim so I played with both the grid and the contact points on my forearm. I really didn’t notice a difference in intensity between the two.

I used it all day at training and didn’t notice any failed stims due to bad contact with the skin like I did with the contact points. I was able to put the collar on a bit looser which I like.

Thanks Lou for mentioning it…..so far it’s working great!!

Does this contact pad work on all e-collars?

No. the spacing between the contact points need to be the same as with the loops on the grid, about 1 1/4". It won't work with bark collars that have the vibration detector between the contact points. Dogtra markets it but TriTronics has been silent on the matter. I don't know if they'll honor the warranty if there's a problem.

Lou, can this be used with a tritronic sport 80c? Or is there something like this for that e-collar?
