Wow! A crustacean locator! I want one! @ 4:35 - stepper motor - @ 5:45 - magnetron - very strong magnet - @ 5:52 - the Toshiba thingy with the red arrow is probably a circulator to isolate magnetron transmitter from receiver input - without that, the mixer diode in the receiver would go "pop" at the first magnetron pulse. - @ 8:40 - the receiver IF amps and probably demodulator stages as well

I'll take your word for it. HA! You are a genius as usual! Thanks for the info. It's a neat chunk of dumpster junk! Soooo, magnetron, as same wavelength as a microwave oven??? Mr. Burns. When the tax check clears,,, guess what!? I'll finally have the shipping cash I've been waiting for, for oh, well, 6 months now!!???? Dang I can't wait. Have a one month old at the house and damn that booger drinks a lot of formula. I just can't wait. Cnt wait ! Steven

Steven King microwave ovens run at 2450 Mhz - i think most of these small marine radars run about 8 Ghz

Hay ya all, um havin a psychic moment on this one... keep the motor and wave guide, trash - EOL the electronics and PCBs,,, Get a nice speaker, mount it aiming into that wave guide, cut a sound slot along that cover, then make it into a mini Leslie!
