Note, regarding the question, 'What is an 'XLT ~ Exceptional Unit'? 

I have now easily serviced a couple hundred lidars. Once in a while an organically, super nice unit comes around. This is that one. Naturally balanced (hold it in your hand when spinning and it's quiet and the spin is smooth as silk!).  The mirror's AR coatings are super consistent and clean. The imaging data is tight (the screen shots are from the inside of my 12x12 office).  It's the gem that shows up in ~1/20.  If you have thoughts of wanting a really nice unit, this is the one. 

Bundle description: Offered is a fully upgraded ‘Plug and Scan’ VLP-32c Lidar, with a new GPS/GNSS unit, all new accessories, documentation and software.  This packaged bundle is ready to scan right out of the box and includes the following:

• The Velodyne VLP-32c Ultra Puck Lidar has no operational hours since serviced (it has .5 hour runtime for testing). Servicing included: 
• The Firmware has been updated to 4.4.0.0, the latest stable release
• The units configuration and calibration has been updated to match the firmware
• A Brand New, upgraded upper bearing has been installed with a high quality NTN (Japan) bearing. Quiet, smooth, deep groove - ABEC-7 (vs. factory installed ABEC-1).  This is a much needed upgrade!
• Drum balanced (rebalanced) more precise than factory
• All lenses and mirrors have been perfectly tightened, cleaned & treated with an optical coating
• The inner laser and receptor mounts have been inspected and tightened
• The inner and outer dome lens (aka 'window') has been cleaned & treated with a Ceramic coating
• Post coil magnets are sealed on the top side to prevent flaking
• Permanente interior motor magnets are inspected and cleaned
• Optical IC on bottom circuit board is cleaned and coated
• Full unit inspected (methodical with checklist)
• Tightening and inspection of all Allen and set-screws
• O-rings replaced with new (preventative)
• Both ring seals cleaned and re-coated (waterproofing)
• Exterior domes lens (window) has been treated with an additional Ceramic UV/waterproof coating
• This bundle includes a brand new factory Velodyne control module with a new 3 m. cable.  A new upgraded Amphenol cable gland has also been added to the control module. This upgrade tightly secures the cable into the module and prevents that dreaded cable twist. 
• The old, heavy M12 connectors have been replaced with modern, brand new (upgraded) hybrid metal/abs M12s These are a waterproof m/f pair that follows the standard Velodyne wire pinout and colors. These are higher quality (smaller and way lighter) than the original clunky factory connectors! 
• All shrink tubing has been replaced with double walled, marine grade tubing. Marine grade has two layers, is  thicker and has an interior glue lining (adheres when heated) to strengthen and waterproof.  This also helps prevent the cable that goes into the unit, both connectors and the interface box from 'cable twisting' (known issues)!
• This bundle also includes a brand new, Velodyne custom configured, u-blox based GNSS (vs old Garmin GPS 18X LVC) with a 3 m. cable. This also comes with the addition of an upgraded flexible 1mm plug & wire sheathing (original from Garmin comes with unprotected wires) .
• Brand new 3' external 12v power extension cord, extra connectors and plugs
• Brand new 12v. 4 a. (upgraded from 3 a.) control module power transformer
• Brand new 6' waterproof, thin ethernet cable (super durable and thin is easier to route)
• A set of new 1/4-20 fastening bolts.

→ Additionally, you will receive continuous, full access ability to download my personal working library (updated ~ 2x/month). The library is currently ~6 GB, is logically organized and contains documents, diagrams, configuration files and various software packages (all legit). This includes every model from Velodyne as well as many other lidar brands. This will have just about every resource you will need regarding your unit including peripherals such as GPS, UAVs, Point Cloud sw, ROS etc. I am confident that you find a ton of value within.

Your new lidar bundle will be thoughtfully packaged by an industry professional.  It will be shipped promptly via FedEx 2-Day, from the USA, within one day of receipt of payment.  International buyers are also welcomed. 

I am also available, post sale, to help in any way, to assist with your success.
