Review: I tested all the major NATO monitor clamp methods and the Smallrig NATO Magic Arm is by far the winner. Here's why: I tested the Smallrig NATO arm 3875... the NITZE field monitor holder N54-H2... the Newer filed monitor holder MA005... and the Smallrig Monitor Clamp 2906B. I did it using the HARDEST thing for a monitor clamp to do: Hold a LARGE caged monitor horizontally, while being adjusted by friction. Final conclusion: 3 of them can hold and adjust the monitor... but the Nato Arm 3875 is the ONLY one that can adjust to level the monitor to align with the horizon and hold its position. This arm also has a MAJOR advantage in that the NATO clamp is opened and tightened by a rotating lever. - All NATO rails are NOT the same width. Some are slightly wider and can then cause you to spend 15 minutes opening and adjusting the clamp to fit them. This defeats the entire purpose of quick clamps. This arm however fits ALL NATO RAILS immediately without tools. This arm is STRONG. - Unlike most of the others it seems like you could hold 2 monitors and have strength to spare, which is GLORIOUS. Second place is the NITZE... which is incredibly strong... BUT cannot adjust the horizon line. This is the best for "centered above camera" monitors if you're not going to use an "arm". SECRET TIP: The tension adjustment socket is hidden in these clamps below the 1/4" screw. You need to bend them 100% forward or backward to expose the tension screw and tighten it. The ONLY one that DOESN'T have a tension screw for tightening the horizontal twist is the NEWER. This is a permanent and obvious disadvantage. ## Features - Extensive Compatibility : Dual ball heads with magic arm features for NATO Clamp and 1/4"-20 Screws (With Retractable Pins) on the end for DSLR cameras, action cameras, LED lights, flashes, etc. - Anti-twist Retractable Pins : Magic arm with the retractable Pins on each end to prevent twisting. The locating pins are retractable spring designs. You can mount it on the accessories with 1/4" locating holes and NATO Rail or with a 1/4" threaded hole and NATO Rail. - 360° Flexible Adjustment : The camera magic arm with an adjustable thumb lever could be adjusted in different positions and angles via both the ballhead and ballhead clamp. It comes with a small magnetic wrench at the bottom to tighten the thumbwheels. - 12Ib Payload : The max load capacity of the magic arm is 12Ib (5.5kg). Firmly fix your field monitor, LED lights, audio recorders, etc. Each ballhead is 0.79 inch (20 mm) in diameter. This item weighs only 0.2 Ib (91g) , making it easy to carry around and store. - Durable and Stable : The magic arm holder is made of CNC-processed aluminum alloy and stainless steel, which is durable. The ball head with rubber rings is more stable. The rubber pads on each end protect your device from scratching. - Notice: Please note that the diameter of the ball head is 20mm and will NOT fit other brands clamps. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BBPXC56L | | Audio Recording | No | | Best Sellers Rank | #7,398 in Electronics ( See Top 100 in Electronics ) #134 in Camera Mounts & Clamps | | Brand | SmallRig | | Built-In Media | SmallRig 3875 | | Color | Black | | Compatible Devices | Camera, Monitor | | Customer Reviews | 4.7 4.7 out of 5 stars (166) | | Folded Size | 4.5 inches (l) x 0.9 inches (w) x 1.7 inches (h) | | Item Dimensions D x W x H | 114D x 23W x 43H millimeters | | Item Weight | 91 Grams | | Manufacturer | SmallRig | | Maximum Weight Recommendation | 5.5 Kilograms | | Model Name | Magic Arm | | Warranty Description | Manufacturer Warranty | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** SmallRig - **Colour:** Black - **Compatible devices:** Camera, Monitor - **Item weight:** 91 Grams - **Product dimensions:** 114D x 23W x 43H millimeters ## Images ![3875 - Image 1](https://m.media-amazon.com/images/I/61iR1lOReJL.jpg) ## Questions & Answers **Q: For 1/4-20 screw, is that arri locating pins?** A: Hi Customer, Greeting.
