"... I have noticed that if you descend to 80 feet and cut your motors..."
It's the killing of the motors that has more effect than the depth.
Now as far as "parascope depth"...
There is a key that sets a default parascope depth but this "depth" is not the only one at which your parascope "works." Even at the default setting your scope can be washed out by waves (even tini ones) and you can lose contacts you're looking at. In other words, you can set depths that are shallower and deeper than what is required to use the parascope, so in effect you have a RANGE of depths at which you can use the parascope effectively without broaching the boat nor totally submerging the scope making it useless. Thus, the default "parascope depth" setting is actually a mid point between a range of possibilitites. That the sound gear doesn't function at the shallow end of this range doesn't bother me because I can use the scope and use the sound gear.
No Problem.
