Review: Replay Prime X Action Camera

    When I was told I would be reviewing an action camera I was a little confused, being a firearm blog I am not really used to seeing electronics come up for review. After I got the Replay Prime X action camera in I understood why they chose to send us one for evaluation.

    In a saturated action camera market there are several choices that one could choose to record whatever they liked, some better than others. In the past that choice was easy, buy the GoPro and be done with it. Replay has introduce a solid contender into the market that offers some unique advantages over the other offerings.

    Before I get too far into things here is the specs from the Replay website. It is quite a lot to read through but I want to make sure I don’t leave anything out.

    The T&E model I got had several attachments and did not arrive in a retail package. As a result I am unsure as to what ships with the Prime X. We can take a look at what they sent me though. Replay sent the camera in a nice zippered case that contained all the mounts and accessories. If you have used a GoPro you know that they aren’t as thoughtful. When I had mine I had to find a bag to contain all the extra mounts and such. It is nice that Replay thought to include one. It is a bit of a tight fit with everything that they included though.


    I laid all the mounts out on the table to see what options I had for testing the camera. They included several bases and four mounts, one fixed, one that had a ball swivel, one that attaches to a tripod, and one picatinny mount. P1020599

    Here is the ball swivel mount, it was nicely constructed and is adjustable to line up some pretty cool shots. I admittedly didn’t used this one because I didn’t want to waste one of the double sided tape pieces. I do think it will be a valuable asset for anyone wanting to mount it to a fixed surface that might not be parallel to what they want to capture on camera. P1020600

    I put the ball swivel mount into the base to see how much height is added and found it to be not that much. Keeping the camera low to the surface mounted to would allow you to mount the Prime X camera in places you wouldn’t be able to mount a GoPro. P1020604

    The bulk of the controls are located under a weatherproof cap on the rear of the camera. Replay saw fit to include a quick guide on the back of the cap. The back of the camera also includes a mini HDMI output, a USB connection that the camera can be connected to a computer with or charged from, and the Micro SD card slot. One large limiting factor I found was the lack of replaceable batteries, you only get 3.5 hours out of the internal battery.P1020601

    The mount bases are offered in both flat and curved flavors. This is especially nice if you want to mount the Prime X to a helmet, in the past some mounting systems have proven to be a bit difficult to do so. P1020602

    The low profile mount that was included was exactly that, very low profile. You don’t have the aiming capability of the ball swivel mount but it does sit lower to the mounting surface. I can see this as being one of my go to mounts. P1020603

    Once I got to the pic rail mount I understood why they sent the camera to TFB. I mounted it onto my Sphinx SDP and plated with the position a bit to get it where I wanted. The mount is incredibly adjustable and by loosening one of the two allen screws you can clock the camera so that it is parallel to the ground no matter what position on the gun it is mounted. The mount also swivels so it can be mounted on the right or left side with the camera hanging below the mount or above it.  P1020605

    Time to get shooting with the camera attached. It was light enough that it didn’t really affect the pistol’s balance. P1020609

    With the Prime X mounted on the left side of the pistol I found it to be a bit in the way. It seems when mounting the camera on a pistol rail one should really mount it on the side opposite to the shooters dominant hand.  P1020639

    In the camera’s current position I was forced to shoot with a teacup grip. Gross. P1020656

    I made some adjustments to the mount to see if a high mount worked better. I was able to get a much better grip on the gun with it mounted in this position. P1020691

    Here is some short video I shot with the Prime X. There is some footage of me shooting it on the Sphinx and some of it mounted on a 930 JM Pro.

    I have to admit, I was a bit impressed with the camera. If you are looking for a low profile action camera the Replay Prime X might just fit your needs. Myself personally I think I might still go for the GoPro because of the amount of accessories available, but the Prime X would be a close second. The Prime X carries a MSRP of $299 with a street price closer to $225. You can learn more by clicking here to be taken to Replay’s website.
