What are these things?

That’s a good question.

The VultureNet is a long range (in excess of 1 mile range) two way, wireless system designed to be easily installed on tip ups and fishing poles to alert the user when a fish is on.  The system consists of a Sensor and Handheld.  The sensor can be easily installed on tip ups and slip bobbers for ice fishing, traps for trapping, and fishing poles for bank fishing.  Additionally, the device can be used to monitor game trails by simply using the trigger magnet feature on the Sensor or by buying the model Motion Detection enabled.
