I thought buy buying the tripod adapter made by vortex these would work perfectly on my crossfire binos, especially for the price. You can't easily tighten these up with your fingers if you have big fingers your out of luck. I realize not all binos are made the same but maybe supply something to add to extend the length. Mine do not tighten up either doesn't matter if you use needle nose pliers on them my binos still will easily move back and forth on the tripod. These are well made don't get me wrong just poor design in my opinion.
FIRSTR UP....What is pictured in SOME of the Amazon photos is NOT what you might get. I evaluated the "thumb screw" Knob model....which is what they are shipping now. Maybe the OLDER Screw Driver Slots would be better, but IF it has the useless and non-functional Plastic Spacer....FORGET IT....read on.
Ordered THREE mounts for testing after spending hours wading through reviews. if you want the VERY BEST system, then try the Outdoorsman Binocular Stud Mount. It is around $70 for Stud and Mount.
BUT....FIRST....what KIND of tripod do you have? IF you have a tripod with a arm coming out the back (so you can tilt UP and DOWN), then I DOUBT you will be happy with ANY tripod mount. The arm sticks out and pokes you in the face or cheek.
I have a nice Bogen (Manfrotto) Carbon Fiber tripod with a Mini Ball (quick disconnect plate) head. You can mount the binocular on the quick detach plate and pop it in and then use the Ball to locate the object and you have complete flexibility. THAT is the Nuts.
MY objective was to find a Mount so that I could use my really nice Steiner 10X binoculars on the shooting range. They are FIXED power and NOT zoom. Work GREAT at 15 Yards. Little marginal at 25 yards, unless you have a WHITE background (think 9" paper plate with a 3/4" DOT in the center). SO, I did not want to spend big bucks for a really nice spotting scope.
OK....I ordered THREE. The Carson TA-50, Leupold Binocular Tripod adapter 118660 and the Vortex VT-400 Adapter. I am keeping the Carson. I tried to find the discontinued Steiner #772 Adapter which is what Steiner USED to sell for the Merlin Series.
The Carson and the Leupold are the SAME mount. Same FACTORY. Different Finish. Leupold is slick powder coated. Carson has a "Crinkle" finish. Vortex is different and is about 1" or so longer.
Carson comes with a KNOW and an O-Ring....use a well and wide fitting Flat or Slotted Screwdriver or you your fingers. Fingers, and I have great grip strength) ain't gonna tighten ANY mount up. You COULD use a Quarter and a small "Leatherman Combo Pliers" tool and probably get it tight.
Leupold is the same KNOB with SLOT NO washer or O-Ring.
Vortex is a long tapered KNOB. Impossible to tighten on the Merlins due to the large objective or tubes. I used a paddd pair of pliers for testing. The Vortex has a plastic (worthless) spacer and a rubber washer.
NONE worked out of the box....but READ ON. I tried a piece of double stick tape (3M Auto Body) cue in a washer shape. NOPE....
For the Merlin, my FIX was a piece of Gorilla Tape. maybe 3/8" square and I cut out a small hole for the 1/4 - 20 screw. Put the tape on the Binoculars as the flat surface would not allow the rubber washer or the O-Ring to really hold.
BINGO....we have a winner. SO, I modified the Binoculars. NOW, my Merlins have a "screw in plastic cover". It will fit nicely and no one will ever see the small duct tape washer.
NEXT UP....the Vortex with the rubber washer was worthless. SO, I do NOT recommend it at all. MIGHT work on other brands...but not for me.
I DID borrow the rubber washer. You can get 1/4" rubber washers at most hardware stores ro Lowes or wherever. CHEAP.
The Rubber Washer OR the supplied Carson O-Ring worked. NOW, I tightened the KNOB with a screwdriver.... The Steiner is made so that the mount is tight against the RIGHT ojective (tube) housing. So, if you want to adjust the width of the lenses for different shooters, you can either adjust the tripod ball and level it out or you can "slighthly" twist or reposition the mount. The O-Ring or Washer does NOT come loose.
I am happy. Keeping the Carson. A "Consumer Reports" Best Buy....with a little shade tree engineering and experimentation.
I made it work with my 12x diamondback binos. It takes a little bit of work but I suppose it's the better than rigging something from scratch. You can cut down the threads, add washers, etc. to get it to tighten down. Or remove the thumb bolt, which is way too long, and replace it with an allen bolt. But that now requires you to carry a tool. I'm disappointed in vortex for it not working better out of the box.
These mounts are frustrating, especially with Vortex 50mm objective binos. It's hard to tighten the screw, and the binos are never fully secure. If you have one set of binos to go from field use to tripod use, this set up is a pain. There's gotta be a better, more secure way to mount binos.
I have Vortex Diamondback 10x42 and this thing is a real pain in the butt to mount on them. The screw knob ends up being in a spot between the barrels where your fingers have a hard time turning it. If I had it to do over again I would suck it up and buy the Outdoorsmans Binocular Adapter.
This will not fit in your chest pouch for binoculars. You need to get the 40$ one.... That one allows you to keep it attached to your glass while it’s in your pouch. This one is for permanent mounting. Basically it sucks for hunting.
The product itself is very sturdy. The problem is that the depth of the screw mount on the binoculars is a little bit shallower than the screw on the adapter. It does not offer any way to reasonably adapt it and keep it tight. The binoculars just sit on the tripod and rocks back and forth.
