Title: Variable ballast
Post by: Rüdiger on June 30, 2012, 03:25:30 PM

Depending on the depth in wich the Towfish should run, the weight can be changed.
I`m using 6 stainless steel weights a.500g that can be moved as needed on the threaded rod.

that is a great idea and certainly takes a lot of work out of adjusting for depth. 
Very simple and easy to adjust..
Good job.
