Just my two cents
I have fished all the older names electric and manual as crew as a kid on charters or for pleasure along the way. Hell we used old thermal printer sonar or the old print disks. I m a bit old school and my belief for least headache and a bit of sweat once in awhile. Hands down manual Scotty's on a tilting swivel base, 5 foot tele boom , couple hundred feet of cable and the setup is bullet proof. Years and years of fish pounding enjoyment hassle free. If I do another boat down the road I would buy them again in a heartbeat no question. You can get them cheap sometimes on kijiji you don't need to get them new( bulletproof)
Cheers
