Picked this up from Jay (Sure Shot Night Vision) over the winter while waiting on my DTNVS. Used it for about 20 minutes when I got it, and it has sat in the safe ever since. Got my DTNVS last month so I no longer need it. It is a L3 20UA WP Unfilmed tube built in a Vyper housing. As everyone knows Jay will stand behind this unit no issues. Super clean tube not one spot listed on the spec sheet (since its a UA tube) It came with a spec sheet and will be included in the sale. FOM of 2146 EBI of 1.3 and Halo of .7 $4,300 plus $50 to ship $4,350. Insured for $4,500.
