How The GiraffeG4 Sentinel System Works

Vehicle with the GiraffeG4 Sentinel Tracking App approaches "Low Clearance" bridge.

The Tracking App measures and downloads the exact height and GPS location of the bridge onto a database.

Driver of 13'4" truck gets a USER App warning that the bridge ahead is too low before the truck is at bridge. They'll take a different route.

How The GiraffeG4 Sentinel System Works for Tree Limbs and Power Lines

“Low Clearance” limb is manually measured.


Driver inputs height and GPS location of tree limb into the Tracking App database.

User App provides a warning and a height flag before they hit the hidden tree limb.

GiraffeG4 Sentinel and APP Instructions


    The system works good.  Thanks again for the personal service.  I really appreciate GiraffeG4 LLC for the amazing personal service.


      I’m glad somebody finally came up with something that can measure tree branches along the road, I knocked the cover off my AC unit last year on a back road in New Hampshire… I’ve tested the GiraffeG4 a few times and I think it’s going to help…I like it so far…

        The Giraffe G4 is the best thing I’ve ever purchased for my RV. It keeps me safe on the roads in Connecticut and protects my wallet, big time! All RV owners should invest in the G4!

          It measures accurately. I would definitely recommend it. Great customer service.



            This is so awesome for our business! We haul equipment and this is great for all the traveling and everywhere we go! Our drivers love it and we do to!

              I’m originally from Georgia, I haven’t made it to Hawaii cause I can’t get there-the other 49 I’ve pretty much covered all of them. I’ve done everything from dump trucking to semi’s over the road, I’ve done a little bit of all of it, I’m 29 years in. If you’re going to NY, Philly or Chicago the GiraffeG4 is a great tool to have. All the bridges are mismarked. I used to haul prefab houses down in Georgia-18ft high. I wish I had the GiraffeG4 back in those days- I wouldn’t feel safe traveling without it anymore. I would recommend it to any driver, all drivers, they should have it.

                Using the GiraffeG4 gives me the extra bit of confidence – along with my high pole to protect the load, if I have contact on the pole and need to back up to remeasure the GiraffeG4 gives me a readout of the height so I can inform the driver of the height. The GiraffeG4 is a great tool for the high pole car operator and for the driver with no pole car. This will give him the measurements as he is slowly going under a bridge that may be mismarked and he will be able to stop and back out and save the load from being damaged. PS: I have fourteen years experience and I think GiraffeG4 will give you the edge to do a great job and to protect the load.

                      I like the GiraffeG4. I have a commercial GPS that has put me places that I didn’t intend to go and I trust it to keep out of trouble. I’d give it 5 stars if it came with a longer coax cable…

                          was looking at a Land Line magazine and saw your ad. Just like you to know I've had one of your Giraffe units on my last two trucks and I can't tell you how many times it's saved my ass. I've had it so long I see your on gen4 and I'm sure I have the gen1 and it's still working great. If you are in a heavy haul you can't go wrong with this product. Thanks again for a product that works and keeps working.
