Yea think having a SI unit up front would be beneficial seeing as how on most smaller local lakes I drop the trolling motor and fish up front the whole time. Just hard to justify putting $2k+ in electronics on a boat you only paid $4k for. Let me ask you this. Can you buy an extra power cable, transducer, and mount and just move a 998 si/di/2d from console to bow for a while until I figure out what I actually use more of? Or are those components really expensive?
