Giraffe G4 Truck FAQs


Q. With the GiraffeG4 System, can I measure a bridge, trestle or tree from a distance before I get there? Because when I reach the  obstacle it might be too late.

A. The engineers explained to me that in order to measure the height of an obstacle from a distance the GiraffeG4 would have to send out a signal to the bridge, bounce it off the bridge, down to the ground and then back to the GiraffeG4…Triangulation! ….Impossible, it’s never going to happen…. wouldn’t be an accurate measurement and might cost a million dollars….

Subsequently, we designed the GiraffeG4 System. Yes, you are under the obstacle but the high points on your vehicle are still behind you…the GiraffeG4 will tell you exactly the height of the obstacle and it will continue to measure until you have cleared the obstacle…It is not too late…  it is too late when you’ve hit that bridge, trestle, tree or gas station canopy, and your trailer is crushed or for RV’ers your AC unit is lying by the side of the road and your roof is damaged…

You may be able to safely proceed , the GiraffeG4 will let you know …

If you do have have to back out or drive a new route, why not do it without extensive and expensive damage…that’s your choice…

Measuring from a distance is never going to happen, protect yourself with a GiraffeG4 System for around $200.

Q. When will it help me?
A. It will help in those situations where there is an overhead obstacle (bridge, trestle, tree) and there is no sign. Or they’ve added 4 inches of asphalt and haven’t changed the sign. Or a tree limb at a campsite that will knock off the air conditioning unit on your RV.

Q. What is the GiraffeG4’s range?
A. It’s range is from 1ft 8 inches to 12 ft. It will measure those heights from wherever it is mounted.That is, if the sensor is mounted at 6ft. It will measure accurately from 7ft. 8 inches to 18 ft.

Q. Will the magnetic adapter affect the signal or the accuracy of the unit?
A. No, the sensor is Pizieroceramic and is not affected by magnets.

Q. I do Pilot Car and survey work, how fast can I be traveling and still get an accurate reading?
A. You can travel up to 30mph and get an accurate reading.

Q. When traveling down the highway I turn it on and I get different readings that jump around?
A. Over 30 mph there is a wind shear effect above the sensor unit that will give you different readings. The unit uses sound waves which bounce off the wind shear.

Q. I live in Canada, will it measure meters?
A. Yes, when you program the unit you have a choice of feet or meters.

Q. Will it work in all weather?
A. Yes , the sensor unit is waterproof, but if it sits in weather overnight it does need to be cleared of snow and ice .

Q. Is there a difference between the GiraffeG4 System for trucks and the one for RV’s?
A. No, the only difference is the packaging. The GiraffeG4 was originally designed for tractor trailers, but RV’s face some of the same overhead obstacle problems.
