Umm, look, a microwave oven
utilizes (would you believe) microwave electromagnetic radiation. That stuff has known detrimental effects upon human tissue. MIcrowave ovens have shielding which contains the energy inside the box. thus you can indeed stand next to one without harm to you or your gonads. Should you remove your gonads and place them inside the oven
, they could be cooked, but would not glow even then. I suppose that being a bachelor you might make such an error of judgement...
The depth sounder
emits pulses of acoustic energy of a frequency too high for the human ear to respond to. The coupling between the transducer and a nearby person both being in the air is very poor. There simply is no hazard to a yard worker, none, zilch.
