    Quality in every aspect!

    I can’t think of one negative feature about the Hydra HS635R. It’s compact, lightweight, accurate, easy to use, the QD mount makes it super easy to use as for all 3 purposes. I spent 3 x’s the amount for a Pulsar and this thermal blows it out of the water. The picture clarity, definition and detail out perform my Pulsar. Luckily the guy I sold my Pulsar to didn’t do his research on DNT Optics Hydra Series Thermals or I’d still be trying to sell it.

    Hydra635 LRF

    Picture is great. Can easily identify objects at 300 yds. Wish the buttons were more distinct for night use. Would like the option to make the reticle smaller. Overall great optic for the money

    HS635R

    Thermal is awesome ! Everything about it is legit. Better that my buddy’s pulsar and ATN, by a long shot. Last time I talked to owner about a year ago and he still owes me a hat and shirt, I’ll be looking forward to that :) kidding. Thanks

    Love it

    Love it. Great scope at a super price. Unless you are a special forces sniper this is all the scope you will ever need. Great also as a stand alone monocular. I sail at night and in the fog and this is a must have.

    Hydra 635LR

    Very clear, love the ballistic compensator for those longer shots. Laser range finder works better then my AGM Varmint. Look forward to future hunts!

    Hydra 635R super impressive

    I was nervous about spending $2500 on a thermal from a fairly new brand on the market like most, but it has been everything I had been hoping for. I really feel that you will get out of them what you put in. You will have to put in the time and learn the buttons before you head into the field because there isn't alot of buttons but each one has 2 to 5 different functions. This thing is light weight and small enough to shove in a coat pocket. The quick attach has been spot on every time and I've had it on and off 100 times. The rangefinder and ballistic calculator is spot on. I ran it on my FX impact M3 out to 165 yards and it shot 1.5" high so I adjusted the BC up in the ballistics and the very next shot went in the center. I've used it as a clip-on in front of a leupold vx5 4 20x52 (not an ideal scope for this)and it works good enough to kill at 100 yards but have not tested this setup farther
    There is one upgrade needed that DNT needs to do is a remote for the rangefinder that can be mounted on the gun forend like the Orical X crossbow scope has. All in all this is a impressive scope and will be getting one of DNTs night vision scopes next.
