Multi Dog Training = Different Clickers?

[Freedom]

I was wondering if anyone has used different sounds when training multiple dogs?

I came across this Clicker+, with 4 possible sounds. I only need 2, as I have Lacey training and will start Marlin soon.

Do you think it important to use different sounds for 2 dogs?

Here it is at Clean Run:

And here is where you can hear the 4 sounds it makes:

I use the same clicker for all 3 dogs.... hasn't seemed to make a difference in how they learn. When I'm working with one dog the others are in down stays. They know when they are being worked and when the click is for them.
If your dog doesn't have a reliable down stay then I would just take the dog being worked into a room by itself. :)

Ok, thanks!

IMO, not necessary. If you're trying to work with only one dog, just go into a different room. I usually go on the back deck with whichever dog I'm working with and everybody's happy. If it's raining, I'll go into a bedroom or the dog room, and a lot of people suggest the bathroom ;)
