LUCKY Portable Wireless Fish Finder for Shore Fishing

Product Information

Finally, can someone explain my the basic of coil inductor (the 2 metallic square coil on the board). I google about this. They have 5 pin. 3 on one side and 2 on the other. I think the 3 pins are like potentiometer that allow to adjust the coil inductance value. The other end is fix and will act like a transformer? In any case, both coil inductor are not clearly connected to an IC. There is some transistors in between. I try to follow the signal path but my misunderstanding of the 5 pin vs the transducer input make this job much harder. I also think that the inductor on the rigth is only for reference signal since I don't see any connection with the transducer while the other one is connected to the transducer. I finded time to look into the circuit in more details. It is too big to be ruled in one post... I would like to share were I am now before I go further. your input will help understanding the next step. Its 2.8” display is again a stark contrast to the stereotype portable gadget.

Of the 16 pins, only 7 are connected and strange enough, pin 9 (IC final output pin is not connected - or I failed to find the link yet). I was expecting a lot from this pin.... (: What this IC do with only 7 pins? Can someone figure this out with my finding below? Somewhere in the process, a timer is needed to control time between pulse and echo. Or the transducer frequency already integrate the time? inch ips screen visual fish finder]-this fish finder is mainly composed of a 4.3-inch ips screen display host and an ip68 waterproof lens to form an underwater camera system. it is a good helper for those who like to fish and breeders: help you observe underwater terrain , monitoring fish, you can also clearly see whether the fish bites the hook through it, making ... In addition to the depth, the LBT-1GPS also shows the water temperature and voltage of both the boat and fishfinder battery on the color display. Its price and size is the biggest deception; the tool is anything but cheap and shoddy. Uh…I think we will do fine without the fuss of cables and wires on the next fishing adventure.

Also need demodulation to remove any AC noise out of the transducer signal and convert to DC. Like a high pass low pass audio filter + DC conversion?
