For me it has been a huge help. Like everyone says it won’t make inactive fish bite but you can change change change to try and get a bite. It may cause you hours of time messing with fish that won’t bite but it should never cost you hours of time fishing water where there are no fish. I personally if at all possible will sadly not fish without it anymore. Also like said it gets expensive first you get the scope and head unit and think your done. Did good got it all on sale. then you want bigger then you want the heading sensor which then you need nema2000 cables and connectors then you’ll want a second unit. Then you’ll want to link it all together which you’ll have to buy a network hub and cables. Welcome to your next addiction. All that said I’d do it all again!
