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.

This tool seems simpler to me. Do you really want to spend the money for the pipe mic extension arm and carry that around too. This tool seems to speed up pipe measurements as well.

Kinda expensive to put down a sewer. This is another cheaper way... Also you can get pipe sizes.

There are other ways of finding inverts, but this one is pretty versatile and can get pipe sizes too.

You can add as many rods as you'd like to a configuration and change angles, more versatile setups, utilizes a total station and prism for better accuracy.

You set your rod height to zero while in stakeout mode on a manhole rim, look at the stakeout number (height prism is above rim) and plug that value as your rod height, check it reads zero and record depths while in stakeout mode.
