Swim Depths
Understanding peg profiles for specimen fishing
This article explains what a peg profile is in CatchMate, why it matters for specimen anglers building long-term knowledge of a swim, and how it connects to the venue map.
What is a peg profile?
A peg profile is a permanent, named set of depth readings attached to a specific venue and peg number — completely independent of any individual session. For example, your profile for a lake might contain:
- Gravel bar · 54in (1.37m)
- Island margin · 24in (0.61m)
- Open water · 66in (1.68m)
Peg profiles persist indefinitely across sessions and seasons.
Why it matters for specimen fishing
Specimen anglers invest serious time investigating swims and locating features. A peg profile turns that effort into lasting knowledge — a personal depth chart you can review before any session and build on over years. Unlike session records, peg profiles are not tied to any single trip; they represent the lake bed itself. Depth profiles outlast individual sessions and remain accurate even when session records have been archived.
How to build a peg profile
You create or update a profile from within any session — live or historical — using two routes:
Per-rod inline editor:
- Tap the Depth button on a rod in the rod roster.
- Enter the depth (e.g.
1.37in the m box, or4ft and6in the in box). - Switch Save to peg profile on and add a label (e.g. Right rod, Gravel run, Zigs).
- Tap Save depth + update Peg X profile.
Swim Depths panel:
- Scroll to Swim Depths in the session and tap Add.
- Add entries for each feature spot — custom label and depth.
- Tap Update peg profile — Peg X to save all entries at once.
Both routes update the same profile. There is no limit on the number of entries.
When the profile syncs to the map
- On every depth save: whenever you tap Update peg profile, the depth marker pins on the venue map refresh immediately.
- When you first drop a peg pin: depths already in the profile are linked instantly when you place the pin on the map.
See Putting specimen swim depths on the venue map for the full pin-dropping walkthrough.
Using the profile during a session
When you open a rod's inline depth editor, CatchMate checks for a peg profile at the current venue and peg. If one exists, Load from Peg X chips appear — one per saved entry. Tapping a chip pre-fills the depth in a single tap, saving setup time at the start of a session or when repositioning a rod during a multi-night stay.
