This is a decent collar. The range isn't as far as we need. The batteries are drain really fast.

older model sd-105/s
does each transmitter have their own frequency and will they overlap and cause both receivers to respond and shock both dogs from one transmitter? or can the transmitter frequency be reprogrammed so the frequency doesn't overlap?
SPORTDOG RESPONSE: This is a great question. On most of our transmitters you can adjust the transmitter channel so that you could have 2 transmitters on the same channel if you wanted to be able to control more than transmitter to control 1 collar receiver. The SD-105/105S/350 does not offer this capability. There is around a 1 in 50,000 chance that 2 transmitters would share a channel. If this has happened to you, give us a call at 800.732.0144 and we can get you fixed up.
