Blue Tip reciever
It's really handy when fishing between docks when you don't have direct line of sight of your flag.
When ice fishing there should be little to no interference issues.
I think a better solution would be for this company to make a simple blue light that you put in your shanty that lights up if ANY flags go up. It take a micro second once out of shanty to figure out which one is up
Has anyone tried getting there money back from the company?
