Interfacing fish finder take 2 - #64 by rixius - Project Guidance

hey i just want to give some update. I've tried to use AJ-SR04M as the driver for fish finder transducer and its work with pretty decent result I know it have diffirent frequency but it still work. I think if we can make 200KHz with just same voltage level as AJ-SR04M it will work fine. I've tried the fish finder (not Aj-SR04M) too in deep ocean and it have about 40 m depth reading limit. next week ill try with more accurate measurement. even tho that AJ-SR04M has 6.5 m limit and since
