App/watch for open water swimming with depth meter

Hello,

I have 3 main activities : hiking, open sea swimming and free diving. IS there a watch or app to install in watch that can do a open sea swimming (distance, time, calories... I don't really need swolf and stuff like that because I swimm with a monofin and all those indications don not work for monifin swimming) and also indicates a depth meter (and diivng time would also be great) ? Because when one do open sea swimming with fins, one often also dive a bit...

Thanks !

  • On the Descent models you can use the Apnea activity.

    On other models, the OW Swim activity profile and a CIQ app for the depth can be used, but the pressure sensor is limited to the depth of some 3m only, so not of a much use for anything deeper than that (besides, that you'll see on the graph where and when you went down, and how long you stayed underwater). I wrote and still use such a CIQ app, but because of the depth limitation, I do not offer it in the Connect IQ store. See a sample data from it below (the last graph at the bottom).

  • have a look at this app: https://www.apnea.me/applications/ 

    not available in the app store (as explained on the web page) and with the general 3m limitation of the newer models. I tried it on my Forerunner 935 and it worked fine with regular diving (no dive computer, but with depth reading and timer). 

  • I've checked on the Descent model in a shop, we didn't find a way to have both distance, swimming time, depth meter and immersion time on the same activity, it seems that, for instance, if one is on an outdoor swimming activity, one has to stop that activity, then enter apnea activity, then switch back to outdoor swimming activity, wich is not very practical and also one can't have a full swimming session activity recorded.

  • I had this app on the fenix 3 HR I had some years ago, the GPS tracking was very unaccurate (very messy GPS track). When you say that you have depth reading on your forerunner 935, does this mean that you don't have the depth limitation appllied by Garmin on the latest models ?

  • The last time i used it, it was without a limitation. But I swapped to a Descent G1 as I wanted a proper dive computer...

    And GPS underwater...?

  • Not GPS underwater of course, but let's say I go fir a 3km or more swimming session with fins or monofin and want to have some depth and immersion time reading (and also recording) while making some freediving dives during the swimming session ? I don't want a dive computer, but more a swimming session recording with the psosibility to have depth and immersion time when I do some dives during the swimming session, up to 20/30m. The other possibility is to have a simple free diving septh meter like the OMER Mistral on the other wrist. I suppose a Fenix 6 can support 20-30m immersions as the fenix 3 did.

    Are you telling you swim with a monofin and have the watch above the surface? Under a swimcap? Or on a buoy? And still bad GPS signal? If so, then it is not a problem of the app. And if not (having the watch under the surface most of the time, as I would expect at monofin swimming) then there is no chance to get the GPS position.

  • You are wrong, it works, but that is not the question. Who spoke about bad signal issues ? That wasn't the query : is there a possiblilty to have depth and immersion display within a swimming app or swimming infos within diving app, or multisport activies combining free dive and open water swimming ? It doesn't seem to be possible.

  • You are wrong, it works, but that is not the question.

    No, GPS does not work underwater, even just a few millimeters of water will attenuate the signal sufficiently. If you get the position while monofin swimming, then the watch must be getting repeatedly above the surface

    Who spoke about bad signal issues ?

    You:

    I had this app on the fenix 3 HR I had some years ago, the GPS tracking was very unaccurate (very messy GPS track).

    The messy GPS track was certainly not caused by the app - that's what I am trying to explain.

    is there a possiblilty to have depth and immersion display within a swimming app or swimming infos within diving app, or multisport activies combining free dive and open water swimming ? It doesn't seem to be possible.

    You can add the depth to the OW Swim activity with a CIQ app (Data Field type), as already mentioned. On newer models, the max depth is limited to 3m, but it is not the case with the Descent models.

  • Are you serious ?????  And I'll let here this very unpleasant conversation because you seem to have difficulties to really understand things and are pretty agressive and always ready to "give lessons", si let me give precisions in order to you to understand the things (if possible).

    Regarding the GPS tracking, it was very bad with the apnea app and GOOD WITH the swimming activity factory app, that's why I said that. This fact was recognized by the developper himself, he didn't, if I understood welll, include good GPS algorithm. At least at that time, the purpose was to mark a specific dive position probably, not making a GPS track.

    Then-, obviously you didn't really swamm some distance with a monofin, I do that for almost 20 years. First of all a monofin can swimm horizontally, not only verticaly for diving, it was made in first time for swimming, not diving. So as a human being usually has 2 arms, generally pointed above the head to have a better water penetration and a better balance that allows to keep the head almost not moving and keep the front snorckel  above the surface as you may know, if you put your wrist a bit above the water one out of 3/4 movement, which is enough to have a GOOD ENOUGH GPS TRACK on a swimming session. You also can use your arms to swimm sometimes (crawling style ? Idon't know the name in english) because having your arms and hands above your head is quite unconfortable if you swimm several kms for a certain time, it relaxes your arms, because satying for 90min with still arms ahead can give some tendontisis, I can ensure you. All that together can make VERY GOOD GPS TRACKS with the proper app in monofin swimming.

    You are unbelievable, I swimm with monofin for 20 years and tell you I can have goog GPS track and you say "No you can't", Quite funny and ridiculous if I didn't have to spend some time to explain what sould be obvious for someone who have a minimum experience in that perticular sport.

    Here is track made by a Amazefit T-Rex Pro, not the best GPS, track is not a perfect line, swimming in waves can sometimes make difficult to have a perfect trajectory, but with no fins swimming the track is not really better if the surface of the sea is not perfectly still. So still not possible to have a correct GPS track in minofin swimming ?



    Do you still think it is impossible to have a proper GPS track while swimming with a monofin ? If it is the cse, I can't do anything more.
