Tigershark problem

[Peter67]

Yesterday i went out for the first time this year with my Tigershark in fresh water. When i went in disc. mode, the Tigershark was falsing all the time. It didn't made a difference if the disc. setting where low or high. It kept falsing. When i went in All Metal mode there was no problem and it didn't false. Anybody an idea what the problem can be?
Thanks.
