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 Depth profiles outlast individual sessions and remain accurate even when session records have been archived.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:

  1. Tap the Depth button on a rod in the rod roster.
  2. Enter the depth (e.g. 1.37 in the m box, or 4 ft and 6 in the in box).
  3. Switch Save to peg profile on and add a label (e.g. Right rod, Gravel run, Zigs).
  4. Tap Save depth + update Peg X profile.

Swim Depths panel:

  1. Scroll to Swim Depths in the session and tap Add.
  2. Add entries for each feature spot — custom label and depth.
  3. 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.
