lawrance paper graph

[rick susor]

Anyone know what a x-15 paper graph is worth?

[Hawgeye]

If in good condition and transducers included by the looks of Ebay, anywhere from $75 to $135. I have one that I am dealing on selling and am going to let it go cheap since I have a contact that is buying my graph paper(19) rolls. It works really well, just is too cumbersome in my 17'er. I wish they made a graph for a good price with as good resolution and processing speed...

Hawkeye have you looked at the New Zercom thats out. It is a Liquid Paper Graph. From what I've seen and heard it should be great. Very Detailed....

[Hawgeye]

Airwave, that Zercom does look great! Is that unit any faster at processing data than all the LCD's out there? That is the biggest thing that I miss about flashers, they are instantaneous, well almost instantaneous!

Airwave and Hawgeye,

You are speaking of the Zercom LPG 2000. You can see and read about it on our web site at; www.zercom.com. Select the LPG 2000 from the menu. To get a pdf file download, click on one of the bottom three buttons on the LPG 2000 shown. To see the additional features and menus in the Super-Users mode, select the top button. You will find that the LPG 2000 is a very adjustable depth sounder with 320 vertical pixels, 16 levels of available grayscale, and many adjustable features.

Want instantaneous readouts? Than check out the RTS window. RTS stands for Real Time Sonar. This is a variable width window that shows information in real time (hence the name), just like a flasher. It looks like a traditional flasher display that has been straightened out vertically, except that the LPG 2000 uses an LCD with 320 vertical pixels. No blown or broken bulbs here. When the RTS window is at a setting of 1 or 2 (out of 8), it shows information as a traditional flasher does - meaning it will flash if a fish enters and leaves the transducer cone angle. In addition, the LPG2000 can show 4 different signal strength levels using 4 levels of Grayscale. How many flashers can do that? The stronger the return signals the darker they are shown. If the fish stays in the transducers cone angle, it shows a steady reading. Now, open the RTS window up on a setting of 3 to 8 and the LPG2000 can show up to 120 different signal strength levels using horizontal lines to show signal strength. For those of you who are familiar with an oscilloscope, it looks like one turned on its side. Sound complicated and hard to understand? Relax, the stronger the return signal is the longer or farther to the right side of the display the return lines will be shown.

I could go on for pages, but I know that it works great on the lake here in Eufaula Alabama! Send me an e-mail if you have questions.
