I recently bought a new skeeter that has the oxygenorator system. I too have notice a difference in the fish in a positive way. For example, fished barren this weekend caught a nice 5 pounder that looked as if it had been through the rigors of spawning. Caught the fish at 7:15a.m and at the end of the day that fish was every bit as mad as the smallmouth that accompied her. Well worth the money and I hear they are easy to install. I believe all you do is hook up to the battery and they automatically come on when there is water covering at least 1/2 the face. Good luck.
