Fox pro hammer Jack

[ruttnbuck]

I've had this hammer Jack for a couple years and last year it started acting up as far as the decoy attachment would only spin around in big circles rather then jump and bounce around like it's supposed too... not sure what's going on with it but I've replaced the batteries of course and it still not right.  Wondering if I should try lithium batteries...  I don't want to send it in for repair if it's something easy,  so has anyone experience this with they're decoy attachment? Thanks
