The beam’s "dead zones" can be very large if you are on slopes or
shelf breaks.
•
In rubber and metal boats (without a double bottom), you can use the
device directly through the bottom of the boat. To do this, pour some water
into the boat (to create a reliable acoustic contact) and press the sensor
to the bottom.
•
Depth measurement through ice is possible on the first ice when it is
homogeneous, without air bubbles and frozen snow. In this case, it is
necessary to ensure reliable acoustic contact between the sensor and the
ice (pour water on the ice or melt a small spot of ice under the sensor with
a lighter).
•
When the sensor is immersed deeply under water (about a meter or
deeper), it is possible to register signals reflected from the surface of the
water, and not from the bottom.
