Installation and Setup of the Tactacam PRM-UMS

Mounting the Tactacam on your Scope Rail

The PRM-UMS mount allows you to securely attach the Tactacam to the side of your crossbow scope. Locate the mounting rails on your crossbow scope. Loosen the mount clamp knob and place the mount over the rail, then tighten the knob to secure it in place. Ensure the mount is level for the best view. You may need to make minor adjustments to the position to ensure the camera has a clear view and does not interfere with the crossbow mechanism.

Connecting the Tactacam

With the mount attached, you’re ready to connect your Tactacam. Loosen the camera clamp knob and slide the Tactacam into the mount channel. Position the camera so the lens faces outward, with the screen facing you. Tighten the knob to lock the camera in place.

Syncing the Wired Remote Control

The PRM-UMS kit includes a wired remote control that allows you to start and stop recording without having to touch the camera. Attach the remote to your crossbow or scope in an easy-to-reach spot. Press the sync button on the back of the Tactacam, then press the button on the remote. The status light on the camera will flash to indicate the devices are paired. You can now start and stop recording using the remote button.

Checking Your View and Settings

Look through the viewfinder to ensure you have a wide field of view that captures the area in front of your crossbow. Make any final adjustments to the camera position or mount as needed. Ensure your desired settings like video resolution and frame rate are selected on the Tactacam. You can choose settings that will capture fast action like 1080p at 60 frames per second. Once your settings are dialed in and view is clear, you’re ready to start recording your hunts.

With the Tactacam PRM-UMS mounted and connected, you’ll be capturing your crossbow hunts with an immersive point-of-view video to share with fellow hunters. Be sure to periodically check your camera view and re-tighten all mount connections to ensure safe and secure attachment before each use.

Scouting and Planning

Before the season opens, scout hunting spots using the Tactacam to evaluate terrain, look for trails, and spot potential ambush points or tree stands. The wide-angle lens lets you see a broad area to find the perfect site. Snap photos or take video while scouting to review and plan your strategy.

Mounting Options

Mount your Tactacam directly to your crossbow for a first-person view of the action. Or attach it to a tree stand, tripod, or other mount to capture yourself and the surrounding area.

The Tactacam’s infrared LEDs allow you to film in low light conditions without spooking wary game.

FAQs – Tactacam PRM-UMS Under Scope Rail Mount for Crossbow

What bows is the mount compatible with?

The PRM-UMS under scope rail mount works with most compound crossbows that have a Picatinny or Weaver style rail. As long as your crossbow has one of these common rail types, the mount should securely attach. Some of the popular crossbow brands it’s compatible with include Barnett, TenPoint, Parker, Excalibur, and Ravin.

How difficult is it to install?

Installing the PRM-UMS mount is straightforward and can be done in just a few minutes. All you need is a flathead screwdriver or Allen wrench to attach the mount to your crossbow’s rail. Once attached, you simply slide your Tactacam camera onto the mount until it clicks into place. The camera can then be rotated 360 degrees to capture the perfect shot. When ready to remove, just press the quick release button to slide the camera off.

Will the mount affect my crossbow’s accuracy or performance?

The lightweight aluminum mount is designed to have minimal impact on your crossbow. At just 3 ounces, it won’t significantly add weight or change the balance of your bow. It also attaches securely to the side of the rail, leaving the top Weaver or Picatinny rail open so you can still use your preferred optics. As long as the mount is properly installed, it should not affect the accuracy or speed of your arrows.

Can I use the mount for anything other than a Tactacam camera?

The PRM-UMS mount was designed specifically for use with Tactacam action cameras like the Tactacam 5.0 and FTS. While its standard 1/4″-20 thread will attach other cameras and small accessories, Tactacam cannot guarantee full compatibility or secure attachment with other devices. For the optimal experience, we recommend using the PRM-UMS mount with a Tactacam camera.
