Is this a good deal for me? Im looking at trying to do some spider rigging for crappie. Would this be a good finder? And is the price good? Is there anything I should watch out for so I dont get conned or tricked into buying something that isnt what it was advertised as? Thanks for any help here. Was priced at $200 and a half hour after I asked what model of the helix 5 it was, Price dropped to $150. Kinda seemed an odd thing to happen after I expressed interest in it? I thought so anyways?
