I don't have that one but a few others. I'd get they're cd to hear the elk and practice ALONE in your truck driving. I like the new "I make a da bulls crazy" or something model, you can get a lot of variety out of it... and of course the Hoochie Mama is a great novice call.
There can be too much of a good thing with antler rattling.
I like to hit the horns together for a good 30- to 40-second rattling sequence and then hang them up and resist the urge to hit them again.
This works to the hunter's advantage, because if a buck has heard it, he may have been 300 or 400 yards away and he comes in and he's not exactly sure where it came from.
When finally is time to rattle again throw a slight change-up into the routine.
The second time, don't rattle as loud...
