..I bought mine from Kellyco when they had lifetime warranties,the 1st of the detecting season of this year,I had to have the battery pack lead replaced ;mine broke off(I always thought the lead since new was too short),so I had them add 2 FEET to it at Radio Shack(Not really;just a few more inches);it was done the next day;charged $5.00-Less than it woulda cost me to ship it to Texas and back...
