I have a complete Batrium Watchmon 4 setup for sale:
It was in service from Jan 2018 to Jan 2025. Everything works, however some of the longmon data wires were cut to extend them, but I have both parts, you just need to reconnect them.
$500 (OBO) USD shipped anywhere in continental US. Contact me for shipping elsewhere. (new was $1100USD in 2018 when I bought it).
