DetailsThe Standard SeaQualizer is our original device. It has three depth settings (50-100-150) to choose from. This device is ideal for fishing in up to 300ft of water for most effective releases. As a rule of thumb fish should be released from between 1/3 to 1/2 the depth at which they are caught. So if you are fishing between 60-300 feet, this is the device for you.
