I noticed an ad showing a new HO coupler that used a magetic wand above it to uncouple. WEB page http://sergentengineering.com/
My question is, have you seen these and do they work. They look fairly close to scale, but are not compatible with Kadees, which I use.
I might use these on models for pictures, since they more real compared to most other couplers.
Please let me know if you have seen or used these.
