Deeper is one of the best-known castable sonar brands, with a lineup that ranges from the entry-level START to the more advanced PRO+ 2. Their pucks connect to a phone app and are popular with shore and ice anglers.
At the time of writing, Deeper’s own sonar units were not consistently listed on Amazon US, so we explain the lineup at a high level (see Deeper’s official site for current models and specs) and recommend strong castable alternatives available on Amazon, plus a mount made for Deeper PRO and PRO+ owners.

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.
