BioSonix is a new product that emits fish feeding sounds through a transducer mounted to you trolling motor. Cost around $700. It supposedly increases fish catch by over 400%. Kevin Van Dam won two E 50s and the Bassmaster Classic this yr. using it and Arron Martens used it when he won this yrs W.O.N. US Open. My question is do ya'll think it is fair to use this product in tournaments where the majority of people would not have one due to the cost?
