Does this model have 2 different ways of showing the waveform-either as a thin line or as a line with the area under the curve filled in? Also, does it come with batteries or a case?

Yes, you can press the button to change the display. One press turns it on, two presses change it, then you continue pressing the button until you get the display you want. It comes with batteries, a case, and a string tie.

Yes, this model does show several different types of display options... It inverts displays (so you can easily read it from left or right hand), it has both line and filled waveforms or no waveforms (just PR and OX) if you want. It came with batteries and I have had this unit for about a year and never replaced the batteries yet... I honestly don't remember whether it had a case, but I have never used one if it did. I just stick it in my pocket or leave it by my bed...

My brother built it into the goggles that come with his steampunk outfit, so he seldom uses the sound response mode. His best guess, though, is that the electronics have to be powered up in order to listen for sounds, regardless of whether there are any, so there would still be battery draw.

If you're asking if it has battery operated voice snippetsNo. It doesn't. At all. =/It's a pretty cool figure nonetheless though.

It comes in a clear, cheapy plastic case and does have a fingering chart. I think it had a short cleaning stick but I'm not exactly sure because I have a ton of those all pitched together.

It does come with a suction cup transducer, which holds extremely well. I don't know if you can wire it directly but it works very well with the battery that comes with it. I have used it for 10 hours straight with no problems. It recharges very fast. Overall I am very satisfied with this sonar.

Yes it does . has audio output and it light. Add your own surveilace software and you can add more features.

no batteries. smooth 360. it also has markings for partial increments (e.g. 45 degrees, etc.)

It has two small LEDs on top of the unit when it is recording, IIRC. One might flash. Easily covered with tape to hide them. I returned mine because the battery mode was useless and quality poor, but probably reasonable for the cost.

There seems to be a battery inside because I have unplugged this several times and it keeps the settings. BTW, I really like this unit. Only issue is the instruction guide, but once you figure out how to do the setting this unit is great.

The output is a modified sine wave, though I don't know what it looks like. I picture it being a pixellated version of the real thing, with an unknown number of successive approximations to the sinusoid (like, step functions rising to .3, .5, .7, 1.0, then down again). I have used the unit to feed into the external power supply to my MS Surface pro, and it worked fine for the last two summers on a fire lookout. As I remember, sometimes it appeared not be charging the batteries in the Surface, but then, later, they would be charged. That might have been a spurious interpretation by the power monitor in the computer. Anyway, it was an excellent solution for back-country use.

This is the second unit they've sent me and this one doesn't work right either. It will tone fine, but does not test the line correctly. But to answer your question, yes, there is a switch to go from test to tone.

With a voltmeter or multimeter. There are also hobby parts that can be plugged into the balance port to sound an alarm when cell voltage gets too low, if you want to check it in the model.

I gave this item as a gift and have not seen it in use, but it does have 2 octaves. It has turned out to be a great energy user for an 11 year old who is learning disabled and autistic. If you have any other questions, I will try to get an answer for you. Hope this helps. -Anna Lucinda

When I purchased mine I got the answer to that in the literature that it came with as a modified Sine wave. However unless you are using this for medical physics the difference between the two is minimal. I hope that helps. Mine has worked fine for running a small refrigerator and TV while we camp.

Flat, with label and small holes underneath (this is the only correct answer on here). I have one. I should know. Also, description says, "Audio & Video Recorder". Mine does not record any audio, so I am returning it.

Yes, came with one small careing that held the light. No batties. It's ok if you just place it in figure chess. But you need two more for more of the effect if you want to display it complete. Lights on and all. Other wise. It's ok just as it is. I did not put my in.

I don't know much about batteries beyond AAA and AA batteries, but the one that came with the scale is flat and round. It says +3V on one part if the circumference, then on the other side it says CR2032
