Tether buoyancy very positive in deep dives

[EliotBR (Eliot)]

Hi @ASCHENATO,

Most likely this is an issue of tether drag rather than increased buoyancy - I suggest you have a read of that thread

@ASCHENATO

I am thinking to add few weights along the tether to keep it a bit more close to a neutral situation.

If the problem is indeed the drag, then you can reduce the drag with a “clump weight” and/or a slimmer tether.
