Replacement tracker not accurate

I just got a replacement cat mini tracker for my cat and it’s constantly saying he’s places he’s not at. It’ll say that he’s home in the power saving zone when he’s clearly across the street. My Apple air tag is more accurate than the tracker. He’s in a spot that is supposed to let me be able to live track him but it’s saying he’s home when he’s actually across the street. His old tracker never did that before even though the battery died faster it was more accurate. I’m not sure what to do.
