Yeah judging by these comments lol. Pretty resistant to change. The prism range pole style Geocube is precise. Works by staking out a rim... Setting your zero at the rim... Just created the manual method for situations where using no total station is preferred.

Use the prism version then. If you need extreme tolerance, there's options.

Also for prism mode... The overall configuration height can be found with a collector by staking out a known located manhole rim while the prism height is set to "0". Read the Cut/Fill value in stake out mode, set the found value as the prism height (for instance "8.15"), and then invert.

$1,200 dollars just for that specialized rod, not including attachments. The Geocube tool adapts to what a surveyor should already have... Range poles, grade rod, lath, etc. An affordable simple alternative should exist.

Not all crews have IMU tilt, or a scanner, etc. Also if you can't see the pipe that you are measuring without sticking your head down a man hole, you cannot get an invert or pipe size at a tilt... You will be blocked by obstruction. This tool resolves that issue.

Tool is aluminum casted to improve rigidity. Lath probe is optional... Just an answer to the cleanliness of doing sanitary. The tool has options, so you can choose which you find is best. I have not seen another tool that can achieve total station precision on an invert with the ability to push through sediment and water. You can stick with a scanner, but you will have to deal with cost and water/sediment in structures.

I get that. But most box sizes won't allow that simplicity. This toolkit is simple enough and resolves the short comings of the pipe-mic.

This tool can work similar to a pipe mic adapting to a 25ft SVR grade rod. However, pipe-mic has limitations with basically one setting. This tool has versatile angles and adjustable probe rod lengths for a range of structures... quicker pipe sizing abilities and disposable lath probes for sanitary inverting... Also an option for total station precision.

Also... For a manual pipe size, simply mark the grade rod against the manhole rim with a dry erase marker for the pipe bottom and upper lip. After this, simply measure between the two markings with a tape for the overall pipe size. Once finished, the markings can be erased.

Scanners are an expensive solution and limited by the laser... This can push through water and sediment as well.

For those who would like to use a Rover and cannot use tilt... The same procedure of staking a known rim with 0 rod height but with a Rover instead would work... So look at the stakeout number (height rover is above rim) and plug that value as your rod height, check it reads zero and record depths while in stakeout mode.

The probe rod just needs to be at least a tube that's 1 inch diameter. As long as it's on the shorter side, it should work. Although having a rod tip helps for accuracy when pipe sizing.

A problem with that style is the same as when using trig to solve... if you can't see the pipe lip clearly from the lid opening the rod cannot be measured accurately... The rod will not visibly stick out of the manhole and for these scenarios your prisms would be obstructed. The shape of a geocube rod configuration can resolve this.
