I have the blue tips alarms you mentioned and I really like them. Pricey they but have not let me down. It sends a signal to my smart phone and the phone plays a ring tone. I use the fishy fishy jingle from McDonald’s. I even modified one of my tip downs to have it on and it works great. I have BD frabil and HT rail style tip ups and all work pretty well except I think the BD’s are a little harder to turn in colder weather. I just have them set for northern and use the others for eyes.
