You are correct that is the one that also does the draw loc thing.
Actually we have one of these HD-24 at our indoor range and yes it does really shoot very well, I was very suprised to watch a friend shoot a 300 5 spot indoor round with the HD-24, even though it looks like a small toy at full draw[8D] It has a very comfortable grip.
The cam on the bow is a Parker Cam and the Modules for Parker Cams work on it. I just got them a Parker SCH Module and they put it on the HD-24.
Shoots very quiet.
Rumor has it they are coming out with one in a larger version.
