Really stupid question x102c

9 posts in this topic

Please don't laugh. I got my new lowrance 102c tonight and my boat is 200 miles away, sooo.....I stuck the transducer in my full bathtub (metal bearclaw type) just to see how it worked. Anyway, I could actually hear the echo off the bottom of the tub and after a couple of minutes became concerned that the echo may be too strong being so close to a metal "bottom". Is it possible to damage anything other than my pride for even having to ask this question?

Not at all,if you put your hand over the puck you will be able to feel the sonar pulsing.Oh yea by the way did you mark anything when you were graphing your tub? grin.gif

Nope, could'nt mark anything, not the minnows I threw in there wink.gif or my hand running under the puck. I guess thats why I got concerned about ruining something

Thanks for setting my mind at ease guys. Glad to get a few laughs on my first post. I'll have to wait till Saturday to try out my new toy for real.

You can also just test it out over a hard surface without getting wet. A hard cover book on the floor does the trick or go into the kitchen.

The depth reading will be wrong doing it this way because sound waves travel more than three times faster in water than in air. Therefore, the graph will show a depth deeper than the actual distance the puck is above the hard surface because it takes longer for the reflected wave to return to the transducer which is thinking it's in a water column. Either way, it'll show that it works!

Yep, it shows a depth reading. No bottom per se, just a bunch of verticle lines from the bottom of the screen to about half way up. I would guess I need to actually have it mounted on the boat and in the lake to see anything like a real bottom picture.

      Was up yesterday.  Tried going out of Stoney Point the sand landing is undo able ice ridge out a ways and did not see any tracks going out.  The boat launch has a pressure ridge in front and looked like ATV were following the ridge  toward the point.\ There were two trucks out there no idea how they got there.  we finally went out of Pine Point.  Ice conditions are perfect. No slush no water on the road,   You cannot get out to the trench from here ice heave between. We drilled some holes and a lot of  5 inch perch. When we were going out we asked if the tullies were biting,and he said no  not yet Seems to shallow out any where out there. The was in excellent shape as a lot of wheel houses were coming out.  4 wheel drive was not used all day.  Ice cleats would have been nice to have.Hope this helps

      Most of the mercury pollution in our lakes is from rain.  That's why lakes deep in the back country also have consumption advisories.

      Drove by Grays Bay this morning. The one and only house left has now partially fell thru. Not sure how this one is coming out.
