gts - get yourself a fine plastic inner tube from a fax paper roll. Cut it about 4" long.With a bit of practise you can produce, admittedly, a much weaker call of varying ages but it works fine during the rut when the beasts are working on half a brain - and that half secured between their rear legs. A 'young' call will bring forth an approach for investigation. A more mature call might bring forth rapid reprisal at the trot so ensure that you ARE carrying a rifle and that you are prepared to shoot the animal you are teasing as a suitable cull.
I was once chased off the hill by a cheesed-off stag after teasing him. It was a downhill run. I didn't habe a rifle but I didn't fall - 'Not sure I was touching the ground either, but what saved me was that the old fellow didn't want to leave his girls for too long and was satisfied to chase me off. I never repeated that game.
