Fishing big glide baits offshore on electronics is a different skill set than fishing them shallow. Here's an advanced breakdown of when and how to work them over deep schools.
When to pick up a glide offshore
The ideal scenario is a school that's extremely grouped up and tight, especially sitting on the bottom - when the whole school rises together, the biggest fish in the group is the most likely to commit. Roaming, actively chasing fish are catchable too, but other presentations may outproduce a glide there. For scattered singles, a glide usually needs an extra trigger - current, wind, cloud cover - something already pushing those fish to want to eat. On a bluebird-sky, dead-calm day, you typically need the competitive pressure of a genuinely large grouped school to get a real reaction. The tell that a bite is coming: watching one or two fish turn and start swimming toward the bait on electronics while working it hard, and then the whole school rising at once until individual fish are no longer distinguishable on the screen.
What positions fish on points and ledges
In summer, current is the primary factor, with forage (gizzard shad, threadfin, bluegill) as the secondary factor. Three area types matter most: the front-facing point (typically gets the most current and holds the most active, biggest fish - the first choice when available), the current break point (where fish roll up to feed, then retreat nearby when current is too strong to hold the main point), and secondary points still related to the main lake (worth targeting once heavily-pressured main areas get hammered and fish relocate to relieve pressure).
Boat positioning and casting distance
Start shallow, hugging the point to check for any active shallow fish, then reposition on the tip of the point facing out deep - the reverse of the typical deep-and-cast-shallow approach, which keeps the naturally-rising bait in the strike zone longer as it's worked back up. When scoping a school, stay as far away as possible: if a school reads 20 feet wide, aim to have its far edge sit 80-90 feet out, make a full 100-foot cast, and give yourself 30-40 feet of working room to pop the bait hard and trigger the whole group - casting too close, directly on top of, or short of an unseen fish risks spooking the entire school before you've even started working it.
Working depth, follow-ups, and color
Clearer water calls for working the bait 10-20 feet above the fish; stained water with 3-4 feet of visibility calls for working much closer, 5-7 feet above their heads. After working through a school with the glide first, switch to a drop shot if fish return to the bottom and reposition, or a jerkbait/minnow bait if they scatter rather than regroup - targeting the individually biggest fish that separated. On color, purple gizzard is the near-constant offshore choice on a full-size Boss; downsize to a Baby Boss with bone in more stained water when local forage runs smaller. Tie direct rather than using a snap for better feel on how the bait is working, especially offshore.
