Fish move with the seasons, and so does the way you should use a castable fish finder. In spring you scan shallow flats; in summer you look for deep, cool water; in fall you follow baitfish; in winter you drop the puck through the ice.
This 2026 calendar explains what to look for each season and which castable finders fit best. Always check your state’s fishing seasons and regulations, which vary by water and species.

2026 Castable Fish Finder Calendar
| Months | What fish are doing | How to use your finder |
|---|---|---|
| March to May (spring) | Moving shallow to feed and spawn | Scan warming flats and creek mouths; watch water temperature |
| June to August (summer) | Seeking cooler, deeper water and shade | Look for drop-offs, weed edges and thermoclines |
| September to November (fall) | Chasing baitfish as water cools | Find bait schools; fish move between shallow and deep |
| December to February (winter) | Holding deep, moving slowly | Use ice flasher mode through holes; fish deep basins |
Spring Tips
Water temperature readings help you find the warmest areas, which often hold active fish early in the year. Keep casts shorter and retrieve slowly over shallow structure.
Summer Tips
Look for sharp depth changes and weed lines. Early morning and evening are often best. GPS mapping helps you mark productive drop-offs.
Fall Tips
Bait balls show as clusters on sonar. Fish the edges of those schools.
Winter and Ice Tips
Only go on ice that local authorities consider safe. Use flasher mode, lower the puck into the hole and watch for fish rising to your lure.
Plan Around Regulations
Seasons, size limits and closed waters differ by state and species. Check your state wildlife agency before each trip.

Reading Castable Sonar: A Quick Guide
- Bottom line: a thick, bright line means a hard bottom; a thin or fuzzy line suggests mud or silt.
- Weeds: appear as upright, wavy marks rising from the bottom.
- Fish: often show as arches or icons; on a castable puck being retrieved, they may look like short dashes.
- Bait schools: show as clouds or dense clusters.
- Drop-offs: look like the bottom line stepping down sharply.
Practice on water you know well to learn how your device shows each feature.
