Park Zone PZ-1600 Precision Parking Aid

I got this unit because my wife would pull into our garage a little too far every now and then. This left a tight space in front of her car where we store cat food, pop, grocery bags, etc. so it always made for a tight fit. The straw that broke the camels back is when my wife cut her left on her front license plate trying to squeeze through. Granted, if she wouldn't have pulled up so far, she wouldn't have cut her leg. But what's done is done so I wanted to look at options to help her park in the garage perfectly every time.The tennis ball idea was the obvious one but I work in the garage a lot so I didn't want to keep walking into a hanging tennis ball. For the $20 price tag, I decided to give this one a shot from Amazon. If I didn't like it I could send it back because Amazon's return process is AWESOME and FAST! No need on this unit though.There are 3 pieces to this unit: the "stop light" (red, amber, green), sensor unit, and coiled phone cord that connects in between them. I simply mounted the stop light on a set of cupboards in front of her car using heavy duty velcro (in case I ever needed to remove temporarily). I installed the sensor unit just below the cupboards about 2 feet away from the front bumper and then connected both with the coiled phone cord.Setup is EASY! Just make sure you have the car parked where you need it and point the sensor toward the bumper. Press the On button (right on the front of the stop light) and it cycles through the lights and "learns" the distance in just a couple of seconds.The unit can detect the vehicle from 16 feet out so when the car approaches the sensor, the green light illuminates. As you get closer to the sensor, it turns to amber and then finally red when you should stop. It works perfectly and best of all, my wife loves it. There are many days when she comes home from work and just wants to pull in the garage and get our of her work clothes but the system is so easy that she takes the extra second or two to watch the lights and stop when she hits red.There is an option to connect an AC adapter on this unit but I am using 15-minute rechargeable batteries so I will opt for the clean installation. Also, even though the stop light unit is mounted on the front of the cupboard, we can still open the cupboard door without disrupting the sensor system. The coiled phone cord can easily stretch to about 4 feet so no worries there.This unit is HIGHLY recommended!

VERY EASY TO INSTALL, I ACTUALLY WANT TO TALK ABOUT OTHER POST I HAVE SEEN ON THIS PRODUCT. FIRST OF ALL THIS PRODUCT DOES NEED A BETTER PROGRAMMING SECTION IN THE BOOK PROVIDED. SO WITH MY ASE CERTIFICATIONS AND DIYS MT WHOLE LIFE , I WANTED TO HELP OTHERS. I FOUND THAT UNIT BY PRESSING BUTTON 1 TIME LIKE STATED UNIT DOES NOT PROGRAM PARKING PLACE CORRECTLY. HOPE THIS HINT SAVE YOU SOME TIME #1 WHEN AIMING LASER OR CELL SECTION TRY NOT TO GET 2 DIFFERENT TYPES OF MATERIAL (EX. PLASTIC AND METAL) I USED THE LIC PLATE.( SOME STATE DON'T RUN FRONT PLATES SO JUST SAYING U SHOULD GET THE POINT. AS MY FUSION HAS PLASTIC THEN METAL CHROME STRIPS IN THE GRILL, IT WAS MESSING WITH THE UNIT, TRUST ME....#2 WHEN PLUGGING MAIN UNIT IN ( IF THIS HOW YOU DO) LETS SAY WHEN SUPPLYING POWER BOOK SAYS PUSH BUTTON 1X AND LIGHTS WILL GO THREW THERE SEQUENCE THEN UNIT IS PROGRAMMED. WRONG. SAVE YOUR SELF A LOT OF TIME HOLD THE BUTTON IN TILL RED LIGHT FLASHES (2 PEOPLE MAKES EASIER) THEN IT WILL GO SOLID WHEN IT GOES SOLID RELEASE THE BUTTON WAIT FOR IT TO GO OUT, THEN BACK UNIT OUT AND PULL TO SPOT. NOTE LIGHT WILL CAUSE GREEN LIGHT NOT TO GO OUT( GARAGE DOOR LEFT OPEN) # 3 HINT WOULD PUT UNIT ABOUT AN INCH TO INCH AND A HALF PAST WHERE YOU WANT YOUR FINAL STOP POINT TO BE. THERE IS A DEGREE OF VARIANCE IN THE UNIT. OTHERWISE WHEN LIGHT GOES RED YOU WILL NEED TO INCH FORWARD ABOUT AN INCH. THAT DON'T BOTHER SOME. HOPE THIS HELPS A LOT OF YOU, AND I AM STILL TRYING TO GET A HOLD OF MANUFACTURE TO FIND OUT IF RUNNING AC OUTLET AND POWER GOES OUT WILL BATTERIES ACT AS A POWER BACK UP. NOTHING STATED IN BOOK. ALSO I KNOW YOU WOULD THINK SO BUT, IT DEPENDS ON HOW UNIT IS WIRED AND I WAS NOT GONNA TAKE APART IN CASE I NEED A WARRANTY RETURN, NO SEALS BROKEN.... AGAIN HOPE THIS HELPS AND I AM SO GLAD TO GET THOSE STRIPS OFF THE FLOOR. OVER ALL I LOVE THIS PRODUCT. HOPE THIS HELPS YA.
