"freediving" floats

There are such floats out on the market with all the bits in place but i guess you want to save the cash and make one yourself. Not a bad idea if you put some time into it. I bet you can even make it better yourself than what you get from a shop. That's my advice though i am not an expert.

I think you want a float that scores at least acceptable in the following aspects:
- floatability - it should be big enough to stay afloat with the weights and a freediver on top of it - be it for an immediate rescue need or just to pull up the weights and line at the end of the dive. Best would be to have a tune made of 2-4 compartments, in case one goes bust, it will still float but this is not the case with a regular auto tyre tubes.
-durability - both from the elements as well as the divers - a duckdive done wrongly and the monofin can cut right through the tube. Best is to have the tube all covered with a durable fabric and tied it up on the top and bottom - middle section.This will also work well if you want to store stuff in the middle of the tube and keep it covered from elements or high waves. You should opt for a bright colour - make it yellow or orange to be visible from afar for boats, skijets and why not, birds who need to take a rest!
-extras - you may want to attach 4-6 clips to which one can easily clip a large items (monofin) or snorkel, camera etc without having to open and close the inner "hatch" of your device.

Hope it helps!

Hi Leighdu,
Have something similar but with a large holed fishing net warapped around it and cable tied together at the bottom. A spool of rope sits on the top and passes through the netting and connected to the weights on the other side. When leaving the spool is drawn up and about 1m left loose the weights then thrown up and over on to the centre of the netting with a seperate line for towing back. Also makes a handy kayak in calm water if you have a paddle.

Check out ADRs other setup. Pretty slick. [ame="http://forums.deeperblue.net/showthread.php?t=66323"]http://forums.deeperblue.net/showthread.php?t=66323[/ame]

just another example.......

The idea is to have less to carry around without compromising your training - two factors to have in mind, type of dives/training and local conditions.

If you plan CW, CNF and there is no or little current - 10-15kg of weights should suffice, I'd say - the line will be fairly straight down (but never perfectly straight no matter how much to put on the line!)

For free imersion or anything else that you want to pull up and down the rope, you may want to double the weight. This also applies for strong currents and bigger waves that can pop up and down your rig. More weight would be a big hassle to handle, in particular to pull it up at the end of the dive unless you plan to leave it in place for a while and use it over several times.

hope it helps

I use for diving in lake only 2kg for constant weight for 50m of line.

The bouy has 60kg bouyancy so very good to go back in free immersion if that is my training. In the sea you would need more depending on line and conditions 5-10kg should be more then enough.
