I guess it also depends on what type of buisnesses you're looking to start?ÿ

@dmyhill really appreciate the input and you are correct, the 0 side of the rod is a standard measuring rod so it could be used for levels, the 10, 20...

@dmyhill the resulting accuracy in the field can be verified by the redundant measurements obtained by the rod quite quickly and easily. Measure using...

@field-dog when a manhole or structure is open and the rod is placed on the pipe there is generally a fair amount of free space to move the rod from 1...

@jitterboogie we are currently developing a longer rod and we are aware of the flex issue with standard rods so we manufacture our rods with aircraft ...

@dmyhill technically the rod is calibrated to the trigonometric principle, so its mathematical accurate. The only error that would occur would be due ...

@field-dog you are correct, the 10, 20 and 30 sides are calibrated to the cosine of that angle, when the level bubble of that side is level the measur...

@guy-townes we have one but its a pain to attach and maneuver into structures and sometimes its unable to reach recessed pipes. it also seems to act l...

@plumb-bill the rod is made from aircraft grade aluminum not fiberglass, so even when fully extended it still does not flex any noticeable amount. it ...

@jim-frame the cool part about the vert rod is that each side is already calibrated, put the rod at 30 and the measurement you read is the cosine of t...
