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! Ideal for all bait boats including the Lake Reaper and is the Fish Finder used in the Lake Reaper with Fish Finders fitted!

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). One reason for its multi-functioning capacity is the portable and compact size of the gadget. It is small enough to fit even in the hand of a petite female, which means you could easily accompany it on a kayak or a small watercraft without it overcrowding your little vessel.

Quality Control

Furthermore, you can also switch to wired mode to make it compatible with your chosen fishing type. Depth Capability 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? After seeing the power of its sonar, I can finally understand why the company calls it one of the best castable fish finders. The puny size of the device has no impact on its sonar potential.

LUCKY Portable Fish Finder Fish Detector Device Handheld

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! 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? 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? Alluding to my earlier comment about wires and space, the unit has wired and wireless modes to let it adapt to the kind of fishing scenario you have in mind. If you have the force to throw it 147ft far, things will run without any glitch. 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.

R&D Capabilities

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. x AA battery box with switch (This is added by ourselves as we think its the best way to power the signal box!)
