Experience in the surveying field since 1675 made possible an echo sounder system
which can considerably streamline the whole depth-measuring process.
The system can be used in dams, harbors, and a variety of other scenes. |

- In dams where the amount of mud piling up is measured. If the amount of mud piling up exceeds the limit, irrigation works, riparian works, and flood control works cannot be done properly.
- At the mouth of a river
- At harbors, for securing enough depth for vessels to dock.
- In first-class rivers
- In fishing ports
- At bottoms of legs of bridges, where excessive mud piling can cause legs to break.
- Flow of mud on riverbeds
- Since the TDM-9000B and the TDC-9B can talk to each other using BlueTooth
connection, there is no need for cable between the two equipment.
That means no more worrying of items on the boat getting tangled up by cables.
- Using the system can cut down on the number of people and time involved with depth-measuring work.
In other words, streamlining the whole depth-measuring work.
- It is now possible to store and manipulate analog data digitally.
- Improvement in accuracy
- Improvement in safety
- Measuring using bamboo poles was the very first form of water-depth measurement.
With this method, the maximum depth that could be measured was 3 meters.
Then, around 1929, came lead measurement, where a weight made of lead was attached to a rope with scale.
Lead measurement was used for military purposes, for finding submarines underwater.
- Around 1950, after World War II, the first vacuum-tube depth meter was developed in Japan.
This type of depth meter, which could measure up to 30 meters in depth, came to be used as a fishfinder.
- In 1963, Tamaya Technics Inc.,
using the 288 years of expertise in surveying since its foundation in the year 1675, has developed the first echo sounder in Japan using semi-conductor.
This is when Tamaya joined the business of water depth measurement for the first time.
Tamaya has been constantly improving qualities and performance of its echo sounders since 1963.
