Swim Depths
Recording swim depths during a specimen session
This article explains how specimen anglers can record swim depths in CatchMate — either per rod using the inline depth button, or across multiple feature spots using the Swim Depths panel.
Recording a rod's depth inline
Each rod in your session's rod roster has a small depth button — it shows a wave icon, or the current depth if one is already saved (e.g. "54in" or "1.37m"). Use it to attach a depth reading to each rod position.
Steps
- Open a session (live or historical).
- In the rod roster, tap the Depth button on the rod you want to record depth for.
- An inline editor appears below that row, labelled Swim depth for this rod.
- If you have a peg profile saved for this venue and peg, a row of chips labelled Load from Peg X appears — tap any chip to pre-fill the depth from your saved profile. This is especially useful on multi-night sessions when you return to a swim you've fished before.
- Enter the depth:
- Metric: type a decimal number in the m box (e.g.
1.37for a gravel bar spot, or0.61for a margin position). - Imperial: enter whole numbers in the ft and in boxes separately (e.g.
4in the ft box and6in the in box for four-and-a-half feet).
- Metric: type a decimal number in the m box (e.g.
- To save this reading to the permanent peg profile as well, switch Save to peg profile on and type a descriptive label — for example Left rod, Right rod, Zigs, or Margin rod.
- Tap Save depth — or Save depth + update Peg X profile if the toggle is on.
What this gives you: The depth is attached to that rod for the session. If you also saved to the peg profile, the depth marker pins on the venue map update immediately.
Tip: If no peg pin exists on the map yet, a toast appears: "Peg X depth saved — Add a Peg X marker on your venue map to see depths there." Tap Open Map in the toast to go straight to the venue map.
Recording depths across feature spots
The Swim Depths panel lets you build a full depth map of your swim in one place, with a bar-chart visualisation of the bottom contour.
Steps
- Open a session (live or historical).
- Scroll down to the Swim Depths section and tap Add.
- Choose a position:
- Quick-select chips (Near Bank, 6m, 8m, etc.) are available, but for specimen fishing you'll usually want to tap the Custom position… field and type your own label — for example 30-yard bar, Island margin, Gravel run, or Open water.
- Enter the depth:
- Metric: type a decimal in the m box (e.g.
1.68for a deep gravel run, or0.61for an island margin). - Imperial: enter feet and inches separately (e.g.
5ft and6in for five-and-a-half feet;2ft and0in for exactly two feet).
- Metric: type a decimal in the m box (e.g.
- Tap Add. Repeat for each feature spot — the bar chart updates after every entry.
- When you're done, choose a save option:
- Save to session — stores the depths with this session only.
- Update peg profile — Peg X — saves to the permanent peg profile for this venue and peg, and refreshes the depth marker pins on the venue map.
What this gives you: A depth chart of your key feature spots, built up across multiple sessions and seasons — invaluable when returning to the same swim under different conditions.
Live vs historical sessions
Both work identically. Record depths in real time as you investigate a swim, or go back to an older session at any time to fill in depth data you didn't capture on the bank. Peg profile updates take effect immediately regardless of when you make them.
