no actually, it seems to want to right itself but I will need the ocean to put it to the test....I have a feeling that it will work with a small flag at that height, but not the large flag.
in my pool (more very strange looks) it would right itself from completely upside-down, which is reassuring
here is the foam i used
any the update on the wishbone material?
well mine is about 12 hours old and has seen 0 dives....so I am not qualified to really answer yet 
I expect that it being a lifeguard product, the plastic is UV resistant, if so, that will last quite a while.
the foam I selected is two part marine closed cell urathane foam and I would imagine that it will be quite durable as long as the can remains intact
well i figure it's gonna crush below 33 ft...given that I am using a 60-80 ft (depends on the day) floatline and a 10 ft bungee, that would have to be in more than 100 ft of water...then the fish would have to run the additional 30 ft of the bungee's stretch to 130 and then pull the float down 30 more ft, so if I am in less than 160 ft of water, it cannot be crushed famous last words
i also think it would have to be a case where a shark steals my spear and fish and takes it away down deep....i agree that nothing I would spear here is big enough to take that float down 33 ft
Well, I finally got around to assembling all the parts of my float and doing my own version.
I ordered a 33" rescue can from the site in this thread and 2lb foam from US composites, got the flag pole at Home Depot and the tubing at Napa auto...I got a 2lb weight.
total cost was
38-can on sale
20- foam, I used about 2/3 of the amount I purchased
2- flagpole
3- tubing
___
63 that I spent considering i had the cable and swivel and mono. i also have enough flag pole left to make at least one more, enough tubing for two more, and enough foam to make a huge mess or for another project I have yet to invent.
Based on my calculations I should be okay within 1 atm and I cannot imagine anything I might run into on the reef being able to come anywhere near that depth...if I go blue water, I would probably use this as the terminal float and attach a string of lobster floats 20-30 ft in front of this to do the heavy lifting IF that is ever going to happen? pretty big IF for me <img src= " srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x" height="23">
some tips for anyone else trying this...
1) pour a small amount of the foam and watch it...learn how long it stays viscus and how long it expands for...I was not on point and made a mess and had to use two holes to properly fill the can
2) in addition to Dan's great idea about sealing the bottom of your flag pole holder, I used two chopstick to act as splints to keep it straight inside the can..I found this to be very nice as the tubing wants to bend slightly and this keeps it straight...also, let the can set with the flag pole in, this also keeps it straight for the initial set.
3) use duct tape to seal the cutout hole over the top and it will hold the expansion and result in a nice flush mount like the one with the flag......DO NOT mis judge the amount of time you will have before the foam reaches that point or it will be a lot harder and foam will pour out and you will be left with a less than awesome flush like the front hole
I used the 2lb foam and 2 lbs of lead..my total can's weight 6.75 lbs
i will likely cut down the flagpole, but I wanted to experiment with my huge flags and see if they had a chance before resolving to cutting it down to as short as possible.
the bungee is to hold the flagpole and flag while down and being transported (i tend to lose things that are not attached, esp in a kayak.
and the swivel is done that way intentionally...it is 400lb mono at about a 10" loop and 600lb SS cable (heatshrink coated) in an 11" loop.....my thinking here is not that they will combine, but that the mono will handle most runs and pulls but if it fails the more stout anchor should hold....trying to approximate a tuna sounding, but in truth, the can will crush before most anything else will fail is my guess.
always interested in criticism.
excellent..... anymore info on these magical tips to help the files run faster would be great.
i use the r3 setting which is 720 at 60fps..i like the ability to go slomo...i do not find the vignetting to be an issue on that setting as it is out in the corners and minimal.
the 1080 stuff is way too large and often will never play right on my POS computer, but it does look amazing on my 56" tv <img src= " height="23" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x">
for me, the key is to mentally gain control over as much as I can...that means relaxing with or without optimal conditions and with or without the immersion reflex.
I do my walks at a local park and I am very random about it... i will jog and then walk and then do an apnea walk, then walk, then jog, etc until I am tired, then I will pick a random object in the distance and try it get there apnea walking...sometimes i go fast, others slow, I try to imagine that it is the surface and there is no breathing until I get there....I find that if I am able to maintain relative calmness in this situation, it is an approximation
btw, that annoying dot in the middle of all the shots is somehow inside the camera not a flaw with Jeff's design....on the plus side, PoPro assured me that if I paid shipping they would clean, repair or replace it as needed, which I very much like in a company 
im gonna take it out sunday..it needs a depth test first without the camera, my plan was to stuff some rice paper in there and take it down to 40 ft a few times...then remove and inspect the paper..if it is dry, throw the camera in there and document some hunting ...if you want to give it a whirl on sat you are more than welcome...gimme a call
the real "proof in the pudding", so to speak, is the last shot..being able to read text demonstrates high resolution
because my neighbors are gross ??
it is heavily chlorinated too, that might add to the poor clarity
and here are the 1080 samples
here are the 960 samples
okay, things are going well so far...rather than upload the massive videos i just went with some screenshots to show the important points...
1) IT WORKS!! not to miss the big picture, the images are sharp and nice and regardless of anything else it is a huge improvement.
2)there is minimal vingietting in the 720 format, more than minimal in the 960 and none in the 1080.
here are the 720 samples
Oh that looks sweet! I'm calling dibs on testing it a little deeper
I figured you'd be up to it <img src= " height="23" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x">
Fletch that is a great looking rig...have you tested it? no leaks? i imagine it might add a little drag on ascent, but it still looks quite low profile.
be careful swinging your head quickly as the added mass might make the mask want to pull away from your face due to the centrifical force.
Howdy Sean, glad you made it over here. the place to be:)
I agree with Dan about diving being the bes training, but I do a similar thing to those tables every once in a while just to get my body used to wanting to breath and not doing it.. I also will do occasional apnea walks (on grass!!! not cement) for the benefit of adding phyiscal exertion and sometimes I will hit the treadmill with a snorkel..that makes for some very funny looks
awesome, glad it is doing the job
make a new thread for your build please
