The second biggest complaint about the strap on the DC 30 was that it did not allow you the option of combining your Gamin Astro collar transmitter with your electronic remote dog training collar. One of the more popular features of the original DC 20 was that it was designed to be worn on the same strap as your ecollar. We lost that option with the DC 30, but we get it back with the DC 40.
The DC 40 will come on it's own strap, but adding your ecollar to that strap or moving the DC 40 to your ecollar strap will be a pretty easy option and can be done with basic tools.
The Garmin straps are 1 inch straps and will fit most Tri-Tronics, Dogtra and older SportDOG collars. You can mount the Astro on a 3/4 inch strap
for smaller Dogtra collars and newer SportDOG systems.
The thing to keep in mind if you want to run two systems on the same strap is that you must get good skin contact for the Ecollar to work properly. The Astro does not require that it be on tight to work, but your ecollar does. Correct positioning of the units will be critical to make sure your ecollar will work consistently.

We have run multiple tests on the DC 40 running them on both 1 inch collar straps and 3/4 inch straps with the remote training collar on either side of the Astro and have not had any issues. While I originally didn't expect to run my systems on one strap, I may just change my mind on that soon. We shall see.
