SOUTH SL20 surveying boat adopts dual spray pumps for the propulsion system, and use differential motion to control driving direction of boat. This propulsion system greatly improve the disadvantages of propeller system in previous products that in case of aquatic plants are sucked into propeller and damage the propulsion system.

Coming with carbon nanofiber material and the innovative hull design, SL20 surveying boat becomes an outstanding hydrographic equipment with small size and lightweight, it is very convenient to carry to the field, and one person is able to accomplish the mission.

With moon pool design which running through the bottom, SL20 is able to carry the ADCP(Acoustic Doppler Current Profilers), echo sounder, RTK receiver or the other equipments,  which makes small boat be a combination system and implement surveying works to be diversified.
