I have one I keep meaning to list for sale. I’ve had it quite a while. It still works. I think the brushes could be replaced as the screen is a bit dimmer and sensitivity seems like its less than it used to be. Bought a tri beam transducer for it and still picks up a 4mm tungsten jig in deeper water on the 12 degree cone angle without any trouble. Will do it on the wide angle too but sensitivity has to be cranked up higher.
If looking to get something cheaper that still functions this one could be an option.
Let me know if you are interested.
