the Benjamin discovery is a great PCP air rifle from all I've read about it.
With the pump the package price can't be beat.
if you want a 'shrouded' PCP, go for the Marauder. it's more expensive but worth the difference.
I'll put up with the noise.
i do not know if optics may be employed on the Discovery as it is supplied with open sights only and the Marauder is supplied for Optics only.
It can bet set up for a scope.
PCP air guns are evolving into high quality hunting and target arms very rapidly.
you'll need the K-valve adapter for your SCUBA tank to feed the Discovery or the hand pump that accompanies it in the combo package often times offered.
Yep, that's being budgeted in
pumping the small reservoir on a PCP by hand up to the 3000 PSI* operating pressure**, can be arduous and boring yet many choose that option for economy purposes.
One article mentioned that it's Sat., all the dive shops are closed and your tanks are out of air. GRAB THE PUMP!
PCP's are very hard hitting and can be accurate to the extreme, however, like other air guns, they are not normally long range shooters.
the world of PCP air rifles is a very challenging and exciting one. the PCP picks up where the springer leaves off in terms of power and accuracy.
another world within the airgun world that's emerging with great promise is the Nitrogen piston and the IGT (Inert Gas Technology) guns.
My first choice was the Benjamin Trail Nitro.
IMO, the PCP has them both, the springers and NP/IGT beat insofar as ease of shooting and accuracy though in what I've experienced thru the years.
like any arm, the PCP can be pellet "Finicky"...mine prefer JSB's
IMO, PCP is the best way to go if you wish to do serious airgun hunting.
*some PCP's require more pressure, such as the Walther 1250 Dominator...4800 PSI
The Discovery works @ 2000psi, one of the things I like about it.
**PCP's may operate on lesser pressures than those shown or recommended, you'll just get fewer shots per refill. my .25 Marauder runs off of 3000 PSI but i get only 20-25 'full power' shots before the drop in trajectory/power.
