Fox Micron Mr+ Fish Bite Alarm. 3 black Fox alarms that will link to the remote speaker. 2 Fox alarms work flawlessly and the third will work if you tap the side to turn it on. I'm not sure what is causing that. The Camouflage alarm is not Fox and does not link to the remote speaker but does work flawlessly. Shipping to the lower 48 of the United States only.  2 of the Fox alarms have covers.
