Freediving Safety Course

(1/3) > >>

Thought I would share this free safety course that Ted Harty published online. It is a great reminder on the safest way to buddy dive and an intro to blackout/LMC rescue. All you have to do is enter your email and create a login. Took me about an hour to go through the content and it is definitely worth it. Below is the link.

I would love to know peoples opinions on Ted's buddy method, and who (if anyone) is currently diving this way. Not calling anyone out at all because I'm just as guilty as the next guy, but I have yet to meet another diver who sticks next to me the whole time and is at the surface within arms reach when I come up. But then again, neither am I. Definitely something to consider.

It is a great method, and should be adhere to whenever possible. The problem here is visibility, it is very difficult, even with a float line to follow your friend during his dive. With deep dives I will usually try and stick as close as possible to my partner and follow with one up and one down. The one up, one down I feel is the best way we can dive safely with low visibility. Let your partner dive, during this start your breath up, watch him surface for 30 seconds to a minute then take your turn. It is very important to observe your partner at the surface for a bit because a black out can happen after they resurface.

Thanks so much for sharing

Just yesterday I added a new section discussing how to provide safety in bad viz. I had several students ask questions on how to deal with this, so I added a new section.I don't need to tell you guys that plenty of people dive where their buddy goes out of visibility.

I will also be adding a new section today or tomorrow on the dangers of hyperventilation.

Thanks for all the effort to put together a great course and sharing it with the community.

The tips for diving in poor visibility were helpful and certainly a real issue in our waters (I mostly dive Sonoma county, sometimes mendocino) where an astounding day is 20 ft vis but its often 5-10ft and plenty of days where I went out and it was hard to see the tip of the spear without a light.  Tracking the float line at the surface works, but wondering what everyone's thoughts are on how to protect your buddy if they black out under water.  Seems common that the floatline is just attached to the gun, which means an SWB would likely leave the diver drifting away from their gun and therefore hard to find or even know if they are in trouble.  When doing freediving for depth in the past I've used a lanyard, but never with a speargun or polespear.  Has anyone ever rigged an easy 'tear off' velcro lanyard to their float line?


Blackouts underwater are rare.  Maybe 10% happen underwater.  Recovering or locating a blackout victim underwater prior to them drowning in poor visibility conditions is highly unlikely.  The most effective way would be to follow the floatline.  In the absence of a floatline, or if the unconscious person releases their speargun you would have to search for them.  Depending on depth, current and other factors, recovery could be a couple minutes after the initial blackout.  With no way to perform CPR in the water should it be necessary, rescue may be unlikely.

If this is really a concern to you I can make two recommendations:

One, get a freedive recovery vest.

Two, don't dive in murky conditions.
