Ive seen that project but not sure it will really work that well given the design choices.
As for 80cm, is a challenge. Especially if the transducer is at this depth and only a few cm from the bottom.
By the time the pulse is received, the transducer is still ringing from transmit, so it is hard to measure.
My boat draft is 60cm, I will be trying also at shallow depths, I think it might have to detect depth an adjust pulse length, perhaps use active dampening and so on.
Despite this other depth sounders I have used can measure below 1 meter depth so not sure exactly what you are doing.
