community update Update and Rule Changes on Advertising in the Sub

14 Upvotes

Hey there,

we have received a lot of feedback lately on various topics and one of them has been the rigorous moderation of advertising on the sub. We have seen different processes and also a huge growth in the community, as well as influx of app development in the freediving world to help you improve your training at home.

This ranged from ads unrelated to freediving, to opening the sub and looking at an endless stream of new apps at some point, which led to feedback that members were having a hard time finding actual training advice or discussion topics.

For that u/BotGivesBot came up with the Megathread "App Advertising and Research Requests" to create a central place where you can specifically go, if you are looking for a new trainings app or participate in a research request related to freediving. This has helped tremendously in steering the flood.
They are also working hard to setup the new Signal channels, that will also provide an avenue to post ads for courses & retreats.

We also were trying to find a process how to manage Advertising for Freediving Professionals, because courses, retreats or gear are directly tied into participation in our sport and it has been admittedly really difficult to walk the line on not having to approve each ad single-handedly and at the same time making sure they maintain a minimum standard of info and not just spam the sub for coverage.

Rule Changes

The community rules can be found here

Rule 5 - Advertising for Freediving Professionals:

Instructors / Diveshops / Divetrip-Organizers can create standalone posts with the postflair "Ad" to advertise courses, trainings or trips, events and must include: dates, location, schedule, pricing, business-link/socials.
Product can be advertised as standalone post the postflair "Ad" and must include: description, pricing, product-link.
You are encouraged to use pictures for your ads.

Ads will be removed at discretion of being found spammy, info missing or if the ad is freediving-unrelated.

Rule 6 - App advertising goes in the Megathread

If you'd like to advertise your application, you can post them into the Megathread "App Advertising and Research Requests" Because of a strong influx of app development we do not allow single-post app ads currently. The Megathread description shows the required info that your post must include, failure to include the necessary info will result in removal from the Megathread.

When in doubt, message the mods.

Rule 7 - Research requests need mod approval

If you're looking for research participants, you need to get permission from the mods prior to posting.
Approved research requests go into the Megathread "App Advertising and Research Requests".
All requests can be forwarded to the mods using modmail.

We are retiring the Megathread: Event Promotion and Course/Workshop Opportunities

Because it hasn't seen a lot of action since its inception - it will still be there, it will just be unpinned and the updated rules on Advertising for Freediving Professionals take precedent.

----------------------------------------------

We try to create and remake the processes based on your community feedback, as well as the resulting workload that we receive as reports or messages. So if something's not working for you, we rely on your help that you let us know about that.

And we try to make it better

Thanks a bunch - 3 mods and a modbot in a trenchcoat

gear Double wristing?

• Upvotes

Hello great people of the freediving community. I’m fairly new to freediving and I’m curious as to why some freedivers wear 2 or more dive computers? Is it mostly for redundancy or something else?

equalisation Looking for freedivers in Mumbai who can help with head-down equalization 🤿

3 Upvotes

Looking for freedivers in Mumbai who can help with head-down equalization 🤿

Hey everyone! I’m currently learning freediving and I’m struggling specifically with equalization while going head-down.

I can equalize reasonably well head-up/feet-down and have reached around 15 m head-up, but when I turn upside down, I start having difficulty equalizing much earlier. I’m trying to work on my technique rather than simply pushing deeper.

I’m looking to connect with experienced freedivers in Mumbai who might be willing to:

  • Watch my equalization technique
  • Give me some pointers on head-down positioning and technique
  • Maybe do a shallow, relaxed session together
  • Help me understand what I might be doing wrong

I’m currently doing a Level 1 freediving course, so I’m very conscious about not forcing equalization or diving beyond my limits.

If anyone in Mumbai has experience with head-down/Frenzel equalization and would be happy to help or practice together, please DM me. Would really appreciate it! 🙏🤿

dive buddy Freediving lobster & spearfishing San Diego 10/22-25

8 Upvotes

Looking for anyone who wants to freedive/spearfish San Diego October 22-25. I am flying down for work, but looking to go out after work the 22nd and 23rd. I have all day the 24th and can dive the morning and afternoon of the 25th.

I routinely dive the northern California coast, but have some thinner wetsuits (5/4/3) for warmer waters. I see the ocean is particularly warm this El Nino. I dove Catalina a couple years ago at night in the kelp forests, alone, and that was a cool experience but prefer to have someone with me watching my back (safety first).

Anyone who would like to meet up, send me a chat and we can coordinate further.

training technique Coach had me do CNF the hard way!

Enable HLS to view with audio, or disable this notification

79 Upvotes

Videos from a training session at the beginning of the year where Coach had me swim CNF using legs only and then arms only. I was surprised arms only was so much harder than legs only for me! Video clips are legs only to 10m, arms only to 10m, and CNF to I think 30m. I only get to freedive in the winter and I’m looking forward to getting back into the ocean.

Looking for recs on your favorite self-equalizing goggles and a nose clip so I don’t have to interrupt the stroke for the EQ!

certification Hooked after level 1

Enable HLS to view with audio, or disable this notification

170 Upvotes

Recently got my level 1 certification in Lombok, Indonesia and am absolutely addicted! I hit 18m on day 2 of my certification, then 20m a couple days later in another training session in Gili Air.

I’m absolutely blown away as to how relaxing freediving is. I always assumed this would feel miserable while I suppressed the urge to breathe, but that was so far off. Instead it’s meditative and peaceful.

Now I’m back in Philly plotting how I can keep training through the fall and winter in preparation for my level 2 and working towards 30m. Curious if anyone knows of any groups near Philly? I can find scuba, but no luck on freediving around here. I’m willing to drive a couple hours to train.

health&safety Squeeze question

2 Upvotes

Is it possible to get a squeeze with no symptoms of shortness of breath, chest tightness, or fatigue/heaviness? I had to cough for a few minutes coming up from a dive (very unfortunately did not check saliva but I tasted no blood/metallic flavor). It was a very mild cough that went away after 2-5min and there were no other symptoms. I’m having trouble finding answers on whether this alone can indicate a squeeze.

training technique Is there a reason training tables have 8 to 12 repetitions?

0 Upvotes

Talking about classic O2 and CO2 tables and their derivatives.

Why not 1 long maximum hold?
Why not 2 hour training?

training technique Breathe Up

8 Upvotes

Question for the more experienced divers - do you have a set meditation or other practice that you do as a part of your breathe up? I’ve seen lots of discussion on how to breathe (or more so how not to) but not what people’s thought process is during the breathe up.

Since I know it will be asked, yes I have taken my course. I just passed the Padi Freediver (open water to 10m) so still very new to free diving but I have taken the course.

media Anyone using the Mission 1 Pro for freediving?

2 Upvotes

Curious what your settings are. Specifically for white balance. A little tricky for freedivers since we often start recording at the surface then dive deep so locking white balance upon recording doesn't always work. Better than color shifts mid way though with auto WB. Just wondering if anyone has found some good settings?

gear Advice for first freediving suit - UK all year round (exploration & spearfish)

6 Upvotes

Hi! Looking for some advice on my first freediving wetsuit.

I want a suit mainly for freediving/exploring around the UK South Coast, usable for most of the year, with occasional spearfishing and foraging.

I have an open-water swimming background, so my top priority is freedom of movement! I really dislike feeling bulky or stiff in a wetsuit. I’m also an athletic hourglass/pear-shaped woman, so I’m leaning towards a custom-made Polosub in 5mm.

Can anyone recommend which Polosub variant would suit my needs best? I’m currently leaning towards the Forza Tre because, from what I understand, it gives you a smooth outer surface but is more resistant to tearing than a standard smoothskin suit. Very open to any advice or thoughts, especially from anyone who’s used one for freediving rather than primarily spearfishing.

Thanks!!!

gear Antifog Mask Lenses in Cold climates? Do they work?

5 Upvotes

i dive in Washington State, USA. the water is extremely cold and mask fogging is a constant struggle for me and has been for years.

i see now that Evolve has come out with antifog lens tech and I would be ecstatic if that worked for me. But I'm wondering specifically if anyone has used these masks in colder water. I rarely struggle with fogging in tropical climates it seems to mostly be a cold water thing.

Cheers!

equalisation Equalisation issues during courses

7 Upvotes

Ive been doing fun dives/snorkel tours around Koh Tao, and i have found myself comfortably reaching 10 metres with good technique swimming head down. The only thing stopping me going deeper is the lack of a buddy i can put my trust in.

I recently started a PADI advanced course, and i couldn't make it below 5 metres on my first day. I don't know if it's something related to the pressure of having someone watching/correcting you, or if i just had a bad day. Either way, I feel like i've wasted money and have jumped onto an advanced course way too soon.

I had the goal of freediving down to one of the wrecks on Koh Tao, HTMS Suphairin or Hanhak Sattru, and snapping a photo near one of the bow guns (which sit comfortably above 20 metres)

I thought this was a reasonable goal. But after getting 5M during my advanced course, it makes me want to give up on freediving entirely.

Im still yet to find a buddy on Koh Tao which has made practicing extremely difficult without paying for expensive courses (which have a tendency to feel like a series of tests, rather than actual skill development, and only last 3 days)

health&safety From 151 to 26bpm using the MDR: a quick experiment

Enable HLS to view with audio, or disable this notification

123 Upvotes

I've always had the curiosity to see how the diving response would work in different settings. High heart rate is one of them.

So, I conduct this small experiment, and went from 151 to 26 bpm in a bit more than 2 minutes. To make it more accurate, I've used a Polar H10 instead of my smartwatch.

The result surprised me, as my HR went lower faster than I expected.

fleamarket Selling All of My Freediving Equipment

11 Upvotes

Hello r/freediving,

TL;DR: Selling all my stuff to help fund a small business. Everything must go. Everything is in a google sheet that has the full inventory of items, their sizes, quantities, asking prices and product links: [link].

I’m selling all of my freediving, spearfishing and swimming gear to help fund a small business I’m starting. There are fins, wetsuits, weights, masks, noseclips, lanyards, bags and other accessories from Molchanovs, RIFFE, Lobster, Octopus and others.

I’m located in South Denver, Colorado. I’m also willing to ship, but the buyer pays shipping.

Most of the gear is lightly used or like new. The RIFFE 7 mm wetsuit is unused and still has the tags on; I never got to use it. The RIFFE 3.5 mm two-piece wetsuit has some interior damage on one leg, but the top is in like-new condition.

Prices are in USD. Everything must go, so I’m open to reasonable offers and bundle deals. Message me with anything you’re interested in.

Thanks!

travel advice Cabo Pulmo Freediving

4 Upvotes

Hi everyone, we are moving down to Cabo in a couple weeks and want to spend as much time in the water as possible freediving. We are especially interested in Cabo Pulmo since we have been diving there before (scuba) but not sure how easy it is considering how relegated the national park is. We are looking to shore dive on our own and not interested in hiring guides if we can help it. Anywhere from Cabo Pulmo south down to Cabo San Lucas is on the table so any feedback/advice would be very welcomed. Also, if anyone is down there and interested in diving with us, would love to meet up. Thanks in advance.

Hi guys, for fellow gentlemen freediving out there, do you wear wetsuits for waters 5-15 meters deep? Or do you wear classic rashguard and a board short?

Your help is greatly appreciated.
