5. A long range beeper that depending on wind conditions can be heard from as far away
as 450 yards and it requires"NO" internal battery


Okay, I'll give. What do you mean "NO" "internal" battery? I have an Innotek beeper that's powered by a battery in the "reciever" at the other end of the collar and I have a Tri-Tronics with the battery in the beeper box. Not sure I like the Innotek style.
