Equipment

Equipment

Track your gear, log its service history, and see at a glance what needs attention before your next dive.

Note

Where to find it: Select Equipment in the navigation rail on the left. The page opens with two tabs: Equipment (individual items) and Sets (named collections).

Adding gear

Tap the + button to create a new equipment item. Every item requires a name and a type; all other fields are optional.

Fields

Field	Notes
Name	Your label for this item — e.g., "Primary reg"
Type	Category (see types below)
Brand	Manufacturer
Model	Product model
Serial number	Useful for warranty and service records
Size	Free text — S, M, L, XL, or a specific measurement
Status	Current state of the item (see statuses below)
Purchase date	Date you acquired the item
Purchase price	Cost and currency code (e.g., USD)
Last service date	Most recent service; used to compute the next due date
Service interval	Number of days between required services
Notes	Any additional information

Equipment types

Submersion recognises 18 equipment types:

Regulator, BCD, Wetsuit, Drysuit, Fins, Mask, Dive Computer, Tank, Weights, Light, Camera, SMB, Reel, Knife, Hood, Gloves, Boots, Other.

Statuses

Status	Meaning
Active	In use and in good condition
Needs Service	Mark items you want to service soon
In Service	Currently at the shop or being repaired
Retired	No longer in use; kept for history
Loaned Out	Lent to someone else
Lost	Cannot be located

Note

"Overdue" is not a discrete status. It is a computed property: when today's date is past lastServiceDate + serviceIntervalDays, the item is flagged overdue automatically. The icon turns red and a warning banner appears on the detail page, but the status field itself remains unchanged.

Service records and maintenance reminders

Logging a service record

Open an equipment item, then tap Add in the Service history section. Each record captures:

Field	Notes
Service type	Annual Service, Repair, Inspection, Overhaul, Part Replacement, Cleaning, Calibration, Warranty Service, Recall/Safety, Other
Service date	Date the work was done
Provider	Shop or technician name (optional)
Cost	What you paid (optional)
Next service due	If you know the next target date, set it here — this updates the item's next-due display
Notes	What was done, parts replaced, etc.

The Service history section on the detail page totals all costs across records and lists every entry. Tap any record to edit it; use the overflow menu on a record to delete it.

Service interval and due date

If you set a service interval on the item, Submersion calculates the next due date as lastServiceDate + intervalDays. The detail page shows:

• Last service date
• Next service due date
• A countdown or overdue indicator (positive = days remaining, negative = days overdue)

When service is overdue, the item's icon changes to the error colour and a banner appears at the top of its detail page.

Maintenance reminders (iOS and Android)

On mobile, Submersion can send local push notifications before service is due. Global defaults live in Settings → Notifications:

Setting	Default / Options
Service reminders	On / Off
Reminder schedule	Select any combination of 7, 14, or 30 days before the due date
Reminder time	Time of day to deliver the notification (default 09:00 local)

Notifications fire when the app launches and — as a backup — during background refresh. Tapping a notification opens the item's detail page directly.

Per-item overrides are available in the edit form under Notifications:

• Use custom reminders — override the global schedule with a different set of day intervals (7, 14, 30) for this item only.
• Disable reminders — suppress notifications for this item entirely, even when the global setting is on.

Leaving both switches off means the item inherits the global settings.

Tip

The reminder system only fires when a service interval is set on the item. If you have not set an interval, no reminder is scheduled regardless of the notification settings.

Equipment sets

An equipment set is a named collection of items — for example, "Tropical" or "Cold water drysuit". Sets let you select a full configuration in one step when logging a dive.

Creating a set

1. Open Equipment and tap the Sets tab.
2. Tap + to create a new set.
3. Give the set a name and an optional description.
4. Select the items to include by tapping them in the list of active equipment.
5. Save.

You can edit a set at any time to add or remove items or rename it.

Using a set on a dive

When logging or editing a dive, find the equipment section and tap Apply set. Select a set from the list to attach all of its items to that dive at once. You can still add or remove individual items after applying a set.

Tip

Sets reference items, not copies of them. If you later retire an item that belongs to a set, the set remains intact but that item will appear as retired when the set is applied.

Tank presets

Submersion includes built-in presets for common scuba cylinder configurations. Presets record the physical attributes of a tank (water volume, working pressure, and material) so you do not have to type them each time you add a tank to a dive.

Built-in presets

Preset	Volume	Working pressure	Material	Rated capacity
AL80	11.1 L	207 bar (3 000 psi)	Aluminum	77.4 cu ft
AL63	9.0 L	207 bar (3 000 psi)	Aluminum	63 cu ft
AL40	5.7 L	207 bar (3 000 psi)	Aluminum	40 cu ft
HP120	15.3 L	237 bar (3 442 psi)	Steel	120 cu ft
HP100	12.9 L	237 bar (3 442 psi)	Steel	100 cu ft
HP80	10.2 L	237 bar (3 442 psi)	Steel	80 cu ft
LP85	13.0 L	182 bar (2 640 psi)	Steel	85 cu ft
Steel 15L	15.0 L	200 bar	Steel	—
Steel 12L	12.0 L	200 bar	Steel	—
Steel 10L	10.0 L	200 bar	Steel	—
AL40 Stage	5.7 L	207 bar (3 000 psi)	Aluminum	40 cu ft
AL30 Stage	4.3 L	207 bar (3 000 psi)	Aluminum	30 cu ft

Note

Pressures for aluminum and high-pressure steel tanks are derived from exact PSI-to-bar conversions (1 psi = 1/14.5038 bar), so they display correctly in both bar and PSI. The rounded values in the table above are for readability.

Custom presets

Go to Settings → Tank Presets to create custom presets for cylinders not in the built-in list, or to add local variants.

Default tank preset

In Settings → Tank Presets, you can mark one preset as your default. The default preset is:

• Applied automatically when you add a tank to a new dive — the volume, working pressure, and material fields are pre-filled from the preset.
• Optionally applied to imports — enable Apply default tank to imports to fill in missing tank fields (volume, working pressure, material) on imported dives that do not include complete tank data. Fields that already have values are never overwritten.

The system default is AL80. Deleting the preset marked as default resets the default back to AL80.

Tip

The default preset sets the physical tank attributes only — volume, working pressure, and material. The start pressure for a dive comes from Settings → Default start pressure, which is a separate field.

Equipment usage stats

On the detail page for any item, Submersion shows how many dives and trips that item has been linked to. These counts are live: tapping the dive count filters the dive list to show only dives where that item was used; tapping the trip count filters the trip list similarly.

The equipment summary (visible when no item is selected on wider screens) shows a quick overview:

• Total items in your catalog
• Active items
• Items with service overdue (if any), with a shortcut to each
• Total purchase value of all items where a price is recorded
