Deeper Smart Sonar is a wireless, castable echo-sounder compatible with iOS and Android smartphones and tablets. Wi-Fi connection enabled to maximize both the distance between the sounder and the device holder up to 330 ft / 100 m and the depth range up to 260 ft / 80 m.
A depth finder may refer to any of the following: Sonar: use of underwater sound propagation to measure depth; Fathometer or fishfinder: a device to locate fish at various water depths; Echo sounding: a technique using sound pulses to measure depth; sounding line: a length of rope used to measure water depth
In this case, no cable drum is required but sophisticated electronics are needed at the transducer and receiver. The display on a net sounder shows the distance of the net from the bottom (or the surface), rather than the depth of water as with the echo-sounder's hull-mounted transducer. Fixed to the headline of the net, the footrope can ...
Underwater housings for smartphones are available with a variety of depth ratings and features. These can be less expensive than dedicated underwater photography cameras. The simplest form is a waterproof pouch, best used for shallow-water photography. [6] Some smartphone housings are limited by operating system.
It provides the operator 180 degrees of selectable coverage via electronic switching of sonar stave arrays circling the towed body. The newest AN/SQQ-32(V)4 upgrade contracted in 2011 includes a high frequency wide band (HFWB) modification that greatly improves shallow-water minehunting capabilities in high clutter environments.

They may be anchored in shallow water, or free-floating in deep water. and may be part of a long term early-warning system, or actively used to hunt down enemy vessels. The position of the target is identified by analysing the time difference of the same sound signals either emitted or reflected from the target and received by three or more buoys.
A sailor and a man on shore, both sounding the depth with a line. Depth sounding, often simply called sounding, is measuring the depth of a body of water. Data taken from soundings are used in bathymetry to make maps of the floor of a body of water, such as the seabed topography. Soundings were traditionally shown on nautical charts in fathoms ...
Water surface searches are procedures carried out on or over the surface of a body of water with the purpose of finding lost vessels, persons, or floating objects, which may use one or more of a variety of search patterns depending on the target of the search, as the direction and rate of drift vary depending on the characteristics of the target and the water and weather conditions at the time.
