Okay, time for this old dog to learn some new tricks. At issue is suspended schools of kokanee, maybe down 40' in 70' of water. My Marcum LX7 will sure point them out in the water column but they roam in schools. If you drill over them you're guaranteed hot action but if you miss the school by fifty paces, you'll never see a one. Been on both sides of that crapshoot. It occurs to me that sidefinder technology may be the answer. Looked at the Panoptix but the laughably low, low sticker price ($1500) stopped my heart. Decades ago the Fishin' Buddy was touted as having that capability but I never heard if they actually worked. Anybody ever turned their fishfinder transducer at an angle and mounted it to enable rotation below the ice? Better ideas out there?Btw--- I put together a dandy jigging machine to pull them over to my location but I still need to get more or less within range for that to work.
There we go. Won't take much Afro-Irish engineering to get something approaching what I had in mind. As appleye reminds us, we used to use re-purposed boat fish finders for that purpose. Which prompted me to check down in my bone pile and there was an old Eagle Fishmark finder that I had bought 30 years ago with just this project in mind. Still in the box unopened. Man, am I getting senile! I'll take it from here. Thank you gentlemen.
I :clap:regret that that the Sonic Ice Hopper that JonPerry mentioned appears to be no longer made. However, the concept of rotating an angled transducer puck surely is no great leap of mechanical engineering.Co_Dinky… the Wolf is a little out of my natural range so I'm working the Mile instead. On that lake they traditionally cruise in an area about 1/2 mile x a mile with a couple of intervening islands and depths from 30 to 90 feet. Up and down the water column chasing plankton. I've got a good jigging machine but as for finding the "highways", I wouldn't know where to begin. Glad you got over them yesterday. Ain't that amazing fishing?
