The transducer can be affected by pressure and/or noise from the prop; I didn't have much trouble with a portable Humminbird unit in that respect (suction cup mounted transducer and an Achilles 14/Honda 40.) The power cable was another story.
Yes you are right it's a Hummingbird, only problem i have had with mine is salt water got into the power outer pin plug and it snapped off,so have to wedge it in,always WD40 it after each trip sure most folk do that and i also have the cable streched out,curled up i don 't beleive the signal is as good when curl up,once speed is slowed down then generaly you get the acurate depth,mine is also suction cup,and i take it off and clip it on my bigger sib,all good tho,Happy sibbing you guy's i have not been out in months and now trouble at home,doh.
