The wetsuit tab recommends a suit for a water temperature. It starts from a ladder of seven temperature bands, shifted by whether you run cold, average or warm, then adjusts the answer from what you logged in similar water, and tells you why in one sentence.

1

Open the wetsuit tab

In Zenfinder, tap wetsuit in the switch at the top. See Zenfinder.
2

Set the water temperature

Under conditions, use the minus and plus buttons beside water temp. This is the same temperature the logbook tab uses.
3

Say how you run

Under you run, choose cold, average or warm.
4

Read the answer

The suit appears at the top under suit, with a sentence explaining it.

​
The ladder

The ladder lists seven bands, from no suit in the warmest water to neoprene drysuit in the coldest. The band for your temperature is marked. By default you see that band and its neighbours; tap show all seven bands to see the whole ladder, and show fewer bands to fold it again. For average, the bands are: cold moves every band to a thicker suit, so at most temperatures you’re recommended one suit warmer than average would give. warm moves the bands toward thinner suits in water of 10 °C (50 °F) and above; below that, it gives the same bands as average, whatever the hint under you run suggests. The ladder on the page always shows the bands for your current setting, in the units the toggle shows.

​
How you run

you run is yours to set. Zenfinder doesn’t change it for you. If your logbook disagrees with your setting, the line under the control says so, for example “your log leans cold: 3 of 4 dives. tap cold to shift the ladder.” This appears when at least two of your dives have a cold or warm warmth felt and at least three in five of them agree. Otherwise the line explains what the control does.

​
How your logged dives change the answer

After the ladder picks a band, Zenfinder reads the dives you logged within 2 degrees of the temperature that have a suit in their wetsuit field and a warmth felt verdict. A dive logged at exactly 0 °C isn’t read.
  • A cold verdict (cold or very cold) in a suit at least as warm as the ladder’s suit says the ladder’s suit is too thin. The answer moves one step up the ladder from the warmest suit you were cold in.
  • A warm verdict (warm or very warm) in a suit no warmer than the ladder’s suit says it’s too much. The answer moves one step down the ladder from the coolest suit you were warm in.
  • Verdicts that agree with the ladder don’t move it: cold in a thinner suit, or warm in a thicker one.
  • If both directions appear, the one with more dives wins. A tie leaves the ladder’s answer.
  • zen never moves the answer.
A single cold dive can move the answer if nothing contradicts it. The sentence under the suit always names the suit and number of dives behind the change, for example “you logged cold in a 3 mm near this temperature on 1 dive, so 5 mm.” If you disagree, change the answer with choose a different suit. Next to each band, chips such as cold ×2 count the dives you logged in that band in exactly that band’s suit. The shorty band never shows chips, because the logbook’s wetsuit field has no shorty option and a logged 3 mm is a full suit. To give Zenfinder more to work with, fill in wetsuit and warmth felt when you log your dives. See Log a dive.

​
While your logbook loads

The ladder’s answer doesn’t need your logbook, so it shows straight away. Until your dives arrive, the sentence says “reading your logbook…”. If they can’t be loaded, it says “couldn’t read your logbook, so the ladder stands alone.” and shows retry.

Add the suit to the weight calc

The wetsuit answer doesn’t change the weight tab until you say so.
1

Check what it replaces

Under for the weight calc, the line below the button says what the suit will replace on the weight tab, for example “replaces 3 mm full suit”, or “the weight calc already wears this.”
2

Tap add to weight calc

Tap add to weight calc. Zenfinder moves to the weight tab wearing the recommended suit.
To use a different suit, tap choose a different suit and pick one from the list. It goes on the weight tab the same way. The suit replaces every body piece on the weight tab (suits, tops and bottoms). Your hood, gloves and boots stay as they were, and the suit keeps the age your previous suit had. A note on the weight tab says what was replaced, with restore previous kit to put it back. The button stays until you change the kit yourself. See Estimate your weight.
The tab says “estimate. test it before you dive.” Check your weighting at the surface before you descend. For more on weighting, see scubazenapp.com/weighting.
