Question Wishbone compatibility

[Kartonschachtel]

Hi,
I'm pretty new spearo and looking to replace some parts of a speargun from a friend which I can use on my travel destination. So I was wondering which wishbone to buy for the Beuchat espadon sport. Do I need to get one from the same brand or are they more or less compatible can I use this one?

Can I also use a dynema wishbone on this gun?
Btw. are the arrows of the same diameter compatible or do I need arrows from Beuchat?
Is it likely to loose an arrow, so should I get some spares?
Thanks for the help.
Kind regards, Oli

All of these are compatible with each other or at least they should be. You'd be better off just using bulk rubber by getting threaded inserts, see pic. They allow to use a dyneema wishbone

Honest opinion about Beuchat shafts: overpriced and mediocre. Used to have only those for over 5 years. Newer ones are better but too expensive for what they got to offer. Just get anything that is 17-4ph steel or/and 45+ rockwell scale (heat treatment) as long as it's cheaper. Beuchat has Euro type trigger mech so pretty much any shaft will do except American ones

...but it looks like it is using a bulk rubber loop band already (or can through a muz-

-zle hole, without need for the threaded adapters?).

I use all Dyneema wishbones now; I started out with a very nice Rob Allen rail gun which used them so I stick with them. But if you use a regular spear, you'll need to smooth out the wishbone grooves so that they don't cut the Dyneema. I did that for 2 very good Omer XXV spearguns which came with good Omer French Articulated Wishbones - I happily used the factory configuration for several years but when it came time to replace the bands I opted to switch to a cheaper, more powerful (& possibly safer for fingers?) RA-style Bulk Rubber loops (so no need for adapters & more rubber for power & stretch) with Dyneema wishbones; having carefully smoothed all the wishbone notches (again, RA-style).

Hi guys,
Thank you very much for your help.
I will both systems, metall and dyneema give a try with 2 shafts.

BTW Dyneema wishbones are also quieter, if the wishbone touches the barrel
