A Pricing Example

$7.83 is the daily expense if your accountant depreciates a $20,000 Watchfire LED sign using a typical 7-year depreciation. Our signs offer powerful advertising that captures the mobile audience. Can your local radio or newspaper deliver promotional messages this effectively for just dollars a day? (This is just an example; an appropriate sign for your location might be more or less than $7.83/day.)

Watchfire Financing Lease

Depending on the size and scale of your Watchfire sign, a monthly payment can be as little as that of a car payment.

From Michelle Yanda, Planning Dept. in the City of Manitowoc, Wis.

"Thank you for taking the time to meet with us about the graphics for our LED sign. Your advanced tips for the Ignite software and coaching for using AVI files were very useful. Watchfire has been exceptionally supportive with technical support since our sign has been installed. We would highly recommend Watchfire based on our first-rate experience you and your staff."

Steve Diveley, Diveley Development Corp. in Danville, Ill.

"I must admit to you that due to the cost of an LED sign, I second-guessed my decision to buy one on more than one occasion, often wondering whether the money may have been spent better elsewhere. Well, it has been just under 8 weeks since the sign was installed and I am becoming increasingly confident that I did indeed make the right decision. Up to the time we went live, our year-over-year sales were ranging from +2% to +5% per week. Beginning immediately, our sales took a fairly substantial jump and have stayed in the +6% to +11% per week ever since. I believe I can accurately say the sign has added from 4% to 6% to our weekly gross sales. It took me a long time to finally make this decision, but now that I have, I am sincerely glad that I did. I just wish I had been smarter 6 years ago when I first began looking into an electronic sign."

Ralph Semb, French King Entertainment Center in Erving, Ma.

"People always comment on our beautiful Watchfire LED sign and how they love the messages. Some even wait at the stop sign to see the temperature. We feel noticed again. Sales have increased. People enjoy returning to our business again. Nothing had changed for so many years; people would just drive by and not even notice we were here. Now-we are noticed again!"
