Nanjing Versacorp Import & Export Co., Ltd. is a portable fish finder manufacturer and exporter. It was established in 2005. Over the past 7 months, we have put our passion and enthusiasm into the development of our new portable fish finder. Now we are proudly introducing an entirely new ultrasonic portable fish finder--- the FF06A to the market. We use the latest ultrasonic technology and algorithms to provide you with a highly efficient and reliable product. We redesigned the human-machine interface to make it more easy to read. We use a three buttons easy program method that is very convenient to operate. We use a PHILIPS and ATMEL processor units to build a complicated information processing center that can analyse thousands of echoes in a second. We use the environmentally friendly material and no lead-based electronic parts to protect the environment. In mass production we use no lead welding technique to keep you and your family members far away from poisonous material. We use the standard mini USB connector and UL approved data wire to avoid any external interference. We use a UL approved printed circuit board(PCB) to provide a stable and reliable system.
