Swim Depths
Putting specimen swim depths on the venue map
This article explains how specimen anglers can link feature-spot depths to the venue map in CatchMate, creating a personal depth chart of the lake bed that persists across every session.
Why peg pins matter
Saving depths during a session stores them in your peg profile, but to see those depths as visual markers on the lake map you also need a peg pin at the right location. Once the pin is dropped, every future depth save syncs to the map automatically — your personal depth chart grows with each session.
Dropping a peg pin to link your depths
Steps
-
Open the venue map — from Venues → [your venue] → Map, or tap Open Map in the depth-save toast that appears during a session.
-
Tap the location on the map where your peg or swim is. The Add Pin sheet slides up from the bottom.
-
Peg is selected as the pin type by default.
-
If you arrived via the Open Map toast from a session, the peg number is already filled in for you.
-
If you have saved depth readings for that peg number at this venue, a cyan preview card appears — for example:
≋ 3 saved depths will be linked
Gravel bar · 54in (1.37m) Island margin · 24in (0.61m) Open water · 66in (1.68m) -
Confirm or edit the peg number; add an optional swim name and notes if you like.
-
Tap Drop Pin.
What this gives you: A peg marker on the map with individual depth marker pins at the same location — one per saved depth entry, each labelled with your feature-spot name and measurement.
Viewing depths on the map
Once a peg pin is in place:
- Open the venue map.
- Tap the peg marker (the fishing-rod icon with the peg number).
- The peg info popup opens.
- The ≋ Swim Depths section (cyan card) lists all your saved depth entries — feature names and measurements in your chosen unit (ft/in or metres).
This works at any time, including between sessions — the depths are read from the permanent peg profile, not from the most recent session.
Auto-sync after the pin is dropped
You never need to re-drop the pin. Every time you save depths via Update peg profile — Peg X in the Swim Depths panel, or use the per-rod Save to peg profile toggle, the map pins update instantly. Over multiple sessions you build up a detailed depth chart of the lake bed without any extra steps.
