buoy for training

[lopen79]

hi
any one can give me an idea how can i make home made buoy that very helpful in freediving training .. i need that one of tube and large pocket in the middle for robe ...what is the material of choice
thank you :martial:martial

 

[Magpie]

A big car or lorry inner tube maybe? Then tie some netting on the inside.

i am planning on ordering one seen near the bottom of this page. I have seen and used them and they are very good:

F.I.I. Freediving Instructors International - from the beginner to the instructor

 

[lopen79]

yes azapa that is what i mean thank you so much
i tried one like this in dahab and it was so practical

This looks very nice! And the price is honestly..extremely low! I think this is ideal for training!

I use something similar to the one azapa has recommended. This one, very heavy duty: Trident Heavy Duty Canvas Divers Float DF95 with reviews at scuba.com

 

[azapa]

that looks real good Eric, maybe even better. I like the optional (of course) flag holder too. I have ordered Martins and will revue it in July (!) when I'm in the states and get my hands on it.

i can honestly say this float is brilliant, i have had one from Martin for a little while now and it works very well. only think it misses is a system for locking the rope off when you are pulling it up. (15kg lead on a 65m rope!) takes it out of you so investing in a yacht cleat system is well worth it. otherwise the material is very robust. keep in mind that you must purchase the tube seperately (about $15) but still a very good foat.

An option that I used before I got that was to just blow up a tire tube and zip-tie a plastic milk crate (stolen haha) in the middle.

Sanso seems to be selling floats and lanyards too now:

[lopen79]

Interesting. There are good 1 m and 1,5 m lanyards, too.
I didn't found any further information about prices etc. Maybe more information by email only?

sport chalet sells a smilair one to erik's but its only $35 for the canvas and the identical heavy duty innertube is 16.99 i beleive. it has handles around the side and lots of spots to hook or tie stuff to... i just had to buy some nylon rope for 10 bucks for 100ft at home depot then tie a 5lb weight to the end..

ACTUALLY upon further looking i can see that it apears to be the exact same one. has a double zipper on top one pouch goes into the center of the innertube and the other is to store stuff youd like to keep dry. except its 20 bucks less.... sports chalet rocks! lol

We live in a huge tide area and as a result....
We'd be adjusting something like this all the time.

If installing in such area's, what can be done to keep the line taught at BOTH ends
for free immersion use as an example ?

Manual line adjustment may be the only way but idea's are welcome.
We could see 2 to 3 meters of height change in a short dive session.

 

[dforcucci]

I use this inexpensive "quick tender" as a way to easily adjust the length of the line and to stop the line off when you are pulling the weight up. We use a 37lb weight so it helps to be able to take a break from pulling it up 120'.
QuickTender

There is also this product which is probably structurally better-

Neat floats. Though as an abalone diver in northern Ca these floats were a dime a dozen. I think Target even used to sell them in Santa Rosa...
They are indeed very handy.

 

[myfish]

That'd be a quick easy adjustment.

I think however that we are going to drop a training line in on a semi
permanant basis using a counterweighted system.

we'll anchor the main rope ( diameter ?, colour ? ) and bring that upto
a system of 2 large bouy's with a semi rigid bridge between them to stop
the counter weight drawing the mainline and counterweighted lines together.

We haven't dived on leashes yet so we are reserving the actual overall design
until we've seen a line/plate/leash system in operation.

A very simple solution is to use a simple long fender buoy and roll the rope arround it:

Yes that seems to be the simplest one I have seen, minimized number of parts . For resting and rescue situations a fender long enough is better than normal round boat buoy....by round boat buoy I don't mean here a freediver's round tube system, which is good too.

This is not so compact or simple, but good:
A selfmade system with 2 buoy (normal round boat buoys are ok in that 2xb construction). There is a 50-60 cm long 20-50 mm galvanised metal tube/pipe between them.
You can put your feet against the metal pipe when pulling up a rope when floating on your back on the surface, it's extremly easy and effective. It's a very big benefit especially when there is a heavy (FIM) bottom weight, or a long rope, or heavy wheather, or in a (bad deep) BO situation a freediver in rope when you are pulling the rope up.

We have one consruction where we have 4 buyos, 2 in both ends, like a minifloat system. The metal pipe is 10 cm over surface and it's covered with soft waterproof insulation plastic, except in the middle where the rope goes down. You can use your old extra neopren - glued as a tube - as cover too. Minifloat system is stable and soft covered metal pipe very good for resting between dives. It's not so heavy system though, we can carry it easy hundreds of meters from a car to water.

If you make a little bigger system with 2-4 metal tubes and maybe a little wood or plate or board or...., you can put there a little electric outboard motor:
Minn Kota Motors
No need for a boat rofl
Waiting for a pic, if somebody already has made a motorised floating system for freediving
If not, the day will be close.

...And yes.... I'm a engineer...with many mobile floating contructions for freediving in my mind...rofl
