a old ( gen.2 ) PVS4 would be on the low 'sucky side' for performance . Pass-up on it unless it a offered to you dirt cheap and you got a few hundred dollars to waist .
And for old mil. weapons NV, With ( Gen3 tube ) . I would take a old Raptor4, or a Raptor6, for a 1st choice, over an old PVS4 fitted with ( Gen.3 ) for hunting Coyotes . But if you got a good deal offered to you buying an old PVS4 fitted with gen.3 tube . You could do pretty good with it on Coyotes .
If it a good price, and that all you got for budget, and it ( gen.3 fitted) . Then get it and use it . then move up the ladder latter when your wallet gets a little fatter .
There old school units and are on the (mil.spec.) heavy side for build weight . They are a low-x fixed-power magnification like around 3.2 or 3.5x . If you fit them with a Gen.3 Tube they will perform and give you a great image . 3.5 power is a perfectly good working magnification .
PVS4 For performance and old ( Gen2 tube ) . they suck, You 'will need' a little moon out and use some IR supplement . You will get a lot of grainy noise static on image when not some ambient Moon out , with relying on IR for illumination most the time .
.
edit add.
If it one of those pvs4 agency turn-in rebuilds, like TNVC was offering several years back, with an upgraded Litton tube Gen3, and better battery supply housing . That would be a good purchase pick for that age of unit .
( for me ) a PVS4 Below that standard . I would pass and shoot for purchasing an old heavy Mil. D740 or 760 body style NV sight for a Coyote hunter .
