Umm may explain some weird noises from my receiver at the w/e as one of
these was being used. Had a look (as you do) IMO it's not precise enough for
feature finding the range isn't anywhere near long enough and the units
sensor needs to be rechargeable at the very least. now show me one that will
give an exact depth under the sensor and bottom make up then were talking
(range of 100 yds as well). Oh and why does the sensor have to look like a
toy boat why not just a plain tube oh well probably wouldn't catch as many
fisherman with a tube.
