THIS IS A DISCONTINUED PRODUCT,THEREFORE NO GUARANTEE FROM MANUFACTURE. GREAT ALARM SYSTEM , REQUIRES 2 AA BATTERIES. WHEN FISH BITES, POLES MOVES AND TRIPS BUTTON FOR A LOUD RINGING SOUND. I MET THE INVENTOR (83 years old), WE BOTH LIVE IN SAME TOWN, AND I OFFERED TO SELL SOME OF HIS PRODUCTS. HE HAS HUNDREDS LEFT, BUT I INDICATED I WILL START WITH A SMALL NUMBER TO SELL, AND AS THEY SELL, I WILL CONTINUE TO MARKET FOR HIM.
