articulated wishbone vs dyneema

Nathan has a mares phantom gun.  He said the wishbone often seems attached then slips off.  Looking at how it is designed I could see it maybe just barely catching.  Any thoughts on the dyneema vs the articulated metal ones?

oh and by the way, the orange float line from dolphin scuba worked out great. 

Most of the articulated wishbones I've seen are ones that have been discarded in favor of the soft style.

I have two Makos with dyneema wishbones and think that's the way to go. I have a Picasso Century with the premade euro screw in bands and articulated wishbone. I bought the band adapters so I can make my own bands. I will be making bands for that gun using dyneema wishbones when the factory band wears out. The articulated bands can be dangerous if a band breaks.

Hey e2g,
Joe here! The orange float line conncted to a mesh bag with ab guts and a rock works out really well! My favorite.

Dump the articulated junk and tie up some dyneema.

With articulated wishbones you must make absolutely sure you seat it correctly into the groove on the shaft.  It is possible to get it in there a bit cockeyed-- it will hold but can let go at any time.  This happened to a buddy and it sliced his hand pretty good as he was swimming while holding the gun midshaft.

With dyneema, you know it's in there right.  Yes, it can break but it sure won't rip your hand or anything else like the metal wishbone will.

2 cents worth,

thanks for the tips guys, dyneema it is.  Of course his loading time was so slow it allowed this old man with a pole spear to out fish him the other day so maybe not

Do you have A pic of that! Im curious to see how it works this weekend!

went by aqua safari in Santa Cruz and the guy said that the shafts that use dyneema have really large grooves so are different than the ones that use the metal.  The one he showed me had little dorsal fins sticking up to latch on to.  He was worried that the dyneema would get cut on the rather sharp indents on the current shaft we have.  I'll probably just round the sharp edges on the shaft groove. Looks like I have to get a whole new band to get the dyneema.

Andy, you sure you want to have a chum slick when you are diving?  

Good point Eugene! Its fun hunting them down anyway!....

You can make dyneema wish bones pretty quickly by unscrewing the plastic caps that hold the articulated wishbone on to the band, then unbolting the wishbone from the caps.  Then insert the dyneema and into each cap and tie it off with a figure 8 knot.  This way you don't have to shorten up the bands to tie in the wishbone the traditional way. 

Many of the euro shafts have very sharp edges, especially on the entry level guns.  If the shaft isn't chrome plated you can sand the edges down and they won't cut through the dyneema.  I have seen the articulated wish bones loose a pin and become "disarticulated" (i.e broken).  I have also seen the plastic caps crack and the wishbones break off.  It seems like a lot of unnecessary possible points of failure.  I like the concept of euroguns, but I think that the Americans got the bands right.
