Really stupid question x102c

Question

jquittum

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.

      Eyeguy and I made it out one last time yesterday. Access points are getting pretty bad in our area. Was finding roughly 2ft of  very chunky ice in the places we drilled holes. With the warm weather and bright sunahine we had, I'm guessing we lost a few inches through the day Fishing wasn't exactly fast and furious, we did get our fish... but really had to work for the quality.  The area we ended up finding our fish was a shallow 6-10ft dark bottom flat, close to where they will move come ice out.   It soon became apparent the fish we were targeting were almost swiming with their back right against the bottom of the ice, infact my two best crappies hit while my bait was only inches below my hole.  Baits we found better success with were the Northland slugbug and The Impulse Mayflies in bright colors. Jig size didn't seem to matter much due to the depth we were fishing. As I am typing this, my thoughts are already turning toward warmer days spent chasing smallies on the river. The boat and yak are soon to be ready, rods will be strung and so on. It was one heck of a long winter.... fished with some real good people from this site I had more good days than bad, got some monster fish locally... for these things I'm truly blesaed.... like I said,It's been a long winter....I'm glad it's over Pic is of my last big ice crappie for the season

      I will certainly keep you informed about the progress of the hatchery. I expect to see the nets and traps go in within the next two to three days. The run should be very strong as the fish are already moving into Pike Bay strongly. Cliff

      Thanks Cliff for your Pike River deteriorating ice reports and pics . I. Really want to show my wife the hatchery when the action is really happening this year , I would assume you will be right on that when this happens , is there any way that you can give a shout out on here as to just when this scenario is happening up there . With the warmer temps being quite steady now , I would think the run will be rather strong this year when things get going ..

      I got the 4 smaller ones the other day. They are a little over 2" long and paid only $6.64 total to my door.  The quality seem pretty good, we shall see once I put them to some use!

      Thanks Leech! Ya you need a life jacket in a kayak. I have mine behind my seat, but Yes I should be wearing it.
