Questions and Answers

Where do you get the name WoBLR?
WoBLR is made from the words “World’s Best Level for RVs”. Our marketing team wanted to create a name that was interesting and referenced leveling; wobbling to level was the comment that generated inspiration.
What is the accuracy of a WoBLR?

The WoBLR is accurate to within .33 degrees of tilt, if you are less than a degree of tilt in both axis the ball and cross hairs will be green. See the RVIQWoBLR App Instructions on using the Zoom function to increase or decrease observed tilt resolution.

Where should I make my WoBLR's home?
The WoBLR can be placed anywhere in the RV, in any orientation.  The Home calibration function will determine two out of three pieces of information, determine which one it needs and prompt you, then zero out the errors and it is Home.

There are two restrictions to consider for WoBLR placement. First, the WoBLR is an inside device, it can be used outside, but is not intended to be stored outside.  Second, we prefer that you mount the WoBLR as square as possible, not perfect, but not tilted too much, or you will get an error message and be asked to try again.

What is the WoBLRs effective working range?
We estimate that the WoBLR will connect and level within ~100 feet.  There are many factors that can change this answer, and they are technical, but since most RVs are much less than 100 feet we feel sure that you will never lose connection due to its range.
Do it require a cellular plan or Wi-Fi to use the WoBLR?
No, the WoBLR is connected by Bluetooth Low Energy, BLE; you do not need to have active cellular service or Wi-Fi to connect to a WoBLR.
My Bluetooth headset cannot go 10 feet, how can your device work at 100 feet?
Bluetooth Low Energy is a version of Bluetooth found in all smart phones developed in the last 5 or so years; you have it and most likely did not know it.  BLE is how health monitors and other new personal Internet of Things devices connect to your Smart Phone.
Why is there a power switch on the WoBLR?
We are RVers, when we design a product we think of RVing and the needs of RVers.  Most folks store their RVs for long periods of time.  The switch allows the battery to be completely conserved during storage.  Otherwise, you would be replacing batteries about once a year if you turn your WoBLR off when not in use, your battery could last much longer.
Can I move my WoBLR to another vehicle?
Yes, you can, but your Home and Hitch calibrations and personalized RV data would need to be re-entered.
My WoBLR turned itself off, then suddenly turned back on, what does this mean?
The WoBLR has hardware features to help you.  A WoBLR will automatically go into power down mode after 30 minutes; this is to save the battery if you forget to turn it off.  Also, in this state, the WoBLR is motion sensitive if it detects motion while in this state it will turn back on.  A tap of the WoBLR will wake it up, but we added this feature so you can turn on your WoBLR when you start your trip and when you arrive at your site the WoBLR will be on and connectable to allow you to see how level your vehicle is at the start, to allow you to reposition to more level ground.
Can I use my WoBLR as a general purpose level?
Yes, you can, it has been used in many general purpose activities.  In camping, we have found it useful to level the picnic table, the grill and always offer to show a friend/new neighbor how the WoBLR works!  In the home is has been a real value leveling appliances and tables.
I have to change my battery; will I have to re-calibrate my WoBLR?
Yes, the WoBLR is a very sensitive instrument, when you change the battery it would be a miracle to get back to the factory calibrated alignment, our unit is that precise.  When you change the battery you must recalibrate Home Calibration.  If you want to calibrate the unit itself after the battery change, you must ensure that your unit is calibrated to a known level surface.  The calibration function is the setting menu allows you to store a new factory calibration.
I have two common jacks on my 5th wheel and am not sure what to put in the jack offset data?
The offset function calculates the arc length a point on the trailer traverse based on the change in attitude of the RV.  Enter the data as requested; the offset will be accurate at all points.
