Not sure why, but they quit making the tri beam, so you'd have to buy a used one - if you can find one.
so at 5' even at a 20 degree cone you would only be seeing 1.75 feet or so. Thanks for the info but the juice isnt worth the squeeze. were not fishing 10" pan fish up here. Half the time we are laker fishing they come in so fast that they dont even register on the flashers.
