We are considering upgrading to an L2 when they become available. Just wondering if there is any market for a used L1. It's a couple of years old and works great, we have had no issues with it.
The Zenmuse L1 isn't particularly expensive to begin with. I run one with an M350 drone and would have a hard time justifying the purchase of a used one unless it priced extremely low, maybe under $1000. Any funds used to purchase a L1 would be better spent on an L2 or Geocue. It's still worth a try, but don't assume you'll be able to sell it for big bucks.
Why not keep the gear. Never understood people selling everything when purchasing something new. It's good to have a backup for all your gear.
I as a solo guy have my first Sokkia Srx5 as a backup for a new Bought IX1201 system, old grx1 as a backup for a new gcx3, Trimble Tx5 scanner as a backup and add-on for a Riegl VZ400i.....
I'm happy to know i can always continu working no matter what happens (breakdown, maintenance,...)
