x7 is 500khz or 500 thousand points per second, x9 is 1000khz or 1 million points per second, so twice as fast to capture the same density of point cloud. Put another way, what you get in 2 minutes on the x9 would take 4 minutes on the x7.
True but still 2 minutes in this day and age is still a long time. with time needed to move the scanner you need say 2.5 minutes per scan minimim so that's a max of 24 scans an hour <200 a day. That's with all other equipment available not productive anymore, let alone the competition of slam.
As scanning speeds improve, receiving the $$$$ for the completed projects seems to be lengthening...;)

Only deliver after payment. I do this for all new clients. First 5 projects or so like this and then i change my due date to 14 days. Never longer.

I don't think the equation is anything like that simple as it neglects things like scanner range, level correction, imaging, running costs, recalibration costs and downtime, IP rating for working environment, scanner weight and portability etc... A device like like the BLK Gen 2 for example is very well suited to shorter range jobs and tight spaces, for outdoor works with longer distances, my feeling is the x9 could be more effective. As scan times reduce, we also have the effect that processing time in the office becomes more time consuming and costly than time in the field. If we're putting in fixed control, it is also the case that there's more to field time than scan time. There are many variables to consider when picking a scanner.

According to Trimble X9 Laser Scanner User Guide the shortest scanning duration is 59 seconds (indoor mode, images off, including self-levelling).
Image acquisition adds 1 minute or more to this depending on image count and HDR setting.

Here is an example X9 slice taken through a pylon, it's been coloured by plane in Undet.
We were only interested in the lower part of the pylon with the platform and cable sealing ends.

(wait for the full image to download)

That is incredible! Thanks for sharing.

I'm interested in using the X9 for collecting data for around 5 powerline structure spans approximately 500 feet apart from each other. Would the X9 be a good instrument choice?

We scan powerlines regularly and I am always on the lookout for a light scanner that can resolve details near the top of tall transmission towers. I have tested the following scanners - scanning the same 50m tall transmission tower.

BLK360 - when the tower is even slightly wet, you get not returns! Its like the tower wasn't there. Even when it's dry, the data is very poor. But that's not what the scanner is designed for.
Trimble X12 - lots of noise, lack of detail. Very poor results.
Trimble X9 - Decent results, but lack of detail near the tops of the tallest towers.
RTC360 - Really good, able to isolate bolts near tower top (X9 could not resolve them), some range noise. Nice data.
Leica P40/50 - Incredible detail, though lugging it over difficult terrain means you need the backpack (and some muscle!). Needed for the very tallest towers, or where distant range is needed.
