Somewhere in the process, a timer is needed to control time between pulse and echo. Or the transducer frequency already integrate the time? I don't know much about LCD. I only know that the depth appears a the top rigth corner. The fish, weeds and stuff may be build out of numerous pixel? Ready to go - easily find where your next catch is hiding with the deeper start fish finder! the lightweight and sleek design makes for a seamless reel without any messy wires or fiddly external batteries required. ideal for shore anglers and family trips who want to get on with catching! Furthermore, you can also switch to wired mode to make it compatible with your chosen fishing type. Depth Capability This has a built in compass which tells you which direction and speed your boat is sailing and the distance to the marker and the home point. This is incredibly helpful for night fishing!

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? There are a number of Fish Finders on the market which run on WIFI connectivity. This limits your range to a maximum of 75 meters which is not enough for most lakes! Our Fish Finder has a 300 meter range which will cover almost all lakes! Ideal for all bait boats including the Lake Reaper and is the Fish Finder used in the Lake Reaper with Fish Finders fitted! Impressive specs - our portable sonar fish finder boasts high-level specs that help you make the most of each trip! casting far out to 165 ft / 50 m and also deep down to 165 ft / 50 m with a 40° sonar beam for ultimate accuracy and coverage. this under water fish finder also has a night fishing mode. I measure 18 pF for all capacitors. Probably it is wrong because all the part are interconnected? I probably read parallel capacitance of the circuit and this is why it is constant?Pin 12 (RSSI output pin) is connected to ground through a parallel arrangment of a 18 pf capacitor and a 1M resistor and it is the only pin that is connected to the microcontroller (pin 1). You can also take help from its shrill alarm to instantly know about the presence of fish in your vicinity. This feature tilts the balance in your favour during nighttime fishing and ice fishing. LCD Display The display is another distinguishing part of this little guy. 2.8” LCD is better than other portable fish finders not only because of the size but also because of the quality of the view. Those are The IF amplifier input pin and IF amplifer bypass pin. (see picture of the typical schematic from the IC datasheet).

built-in 5000mah battery]-this visual fish finder has a built-in 5000mah rechargeable battery, which can be used continuously for 5-8 hours when fully charged; it can also be charged with a power bank, which is convenient for outdoor use; 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? This model has a small handheld device with a rechargeable battery, upgraded sonar & receiver box + battery box with switch to power the receiver. All needed to work with the lake reaper & other bait boats!The screen contains three colour tone adjustments along with tinkering options for fish icons. Meaning, you can fine-tune the unit to make it more responsive to the planned fishing type.

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. 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. We have made sure this fish finder comes with everything you need to work with the lake reaper and other bait boats! 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 ... 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.Smart technology - use innovative, cutting-edge technology to your advantage with our fish finders & depth finders. by generating its own wi-fi, our start depth fish finder won't eat up your mobile data and automatically saves every scan with time and location for easy revisits! I tried to connect to the microcontroller with a serial device on the soldering pad. They are connected to RX / TX of the microcontroller, V+ and gnd. But I was not able to see or trigger any data transfer event. I used realterm and a rs232 cable "spy". Rx or tx was not blinking or doing anything.
