Set of 3 Nash r3 bite alarms and receiver in excellent used condition. They are fully tested and all the various functions work as they should. They also have batteries fitted and are working perfectly. They are all red led heads. Please study the pictures for condition as you’ll see they are really good. I’ve set the heads to 1/3/5 on the receiver but you can change that if so wish. I’ve copied the following from the tinterweb
