Sent in all my info and they declined it, said my receipt was not proof of purchase. What? Said it didn’t have paid in cash or paid with Visa of whatever on it. I went on to ask if she could tell me how I can purchase the update and she told me I would have to call Lowrance so I asked her who she worked for and you guessed it, she said Lowrance. I’ve got $8000.00 worth of Lowrance products on my boat and they giving me grief about $35.00.
