Yes, I've checked the output. On my wrist it's not detectable, on my neck it is. I CC'd fetch per Smartwork and I think I have a decent read on the amount of pressure she requires. I believe I used nicks on the CC fetch. She has been CC to here, sit, heel and kennel. When finances allow the ARC collar will be replaced, not a fan. All that said, my session to pile last night was without pressure, without my hand over her head from heel. She did well. I think I'll work that a couple times and reintroduce the pressure enroute.
