Spotting Scope Phone Adapter: How MuleyCam Works
May 07, 2025
If you want to capture what you are seeing through binoculars or a spotting scope, a phone adapter has one job: hold the phone and optic in alignment without turning the setup into a complicated project. The MuleyCam was designed as a universal phone-to-optics adapter for hunters.
It uses spring-loaded jaws to hold the phone and an adjustable three-prong attachment to connect to a wide range of binoculars and spotting scopes.
What Is a Spotting Scope Phone Adapter?
A spotting scope phone adapter positions a phone camera behind the eyepiece of an optic. Once the camera is aligned with the exit pupil of the binocular or spotting scope, the phone can capture photos and video through the optic. This is commonly called digiscoping.
For hunters, that can be useful for recording animals at distance, reviewing antler characteristics, sharing what you are seeing with another hunter, or simply saving footage from a scouting or hunting trip.
How MuleyCam Holds Your Phone
MuleyCam uses spring-loaded jaws designed to accommodate phones with a wide range of sizes and cases. That means you do not need a phone-specific adapter every time you change devices.
The body is made from aircraft-grade aluminum alloy for a strong, smooth field-ready design.
How MuleyCam Attaches to Binoculars and Spotting Scopes
On the optic side, MuleyCam uses an adjustable three-prong attachment designed to fit a wide range of binocular and spotting-scope eyepieces. Adjust the attachment around the optic, secure it, and then align the phone camera with the eyepiece.
How to Set Up MuleyCam
1. Secure the Phone
Place the phone in the spring-loaded jaws and make sure it is held firmly.
2. Attach MuleyCam to the Optic
Position the three-prong optic attachment around the eyepiece of the binocular or spotting scope and secure it.
3. Align the Camera
Open the phone camera and adjust the phone position until the image through the optic is centered on the screen. Small alignment changes can make a large difference in the usable image.
4. Stabilize the Optic
For the best results, support the binoculars or spotting scope on a stable tripod. A steady optic makes it much easier to keep the phone aligned and capture usable footage.

MuleyCam With Binoculars
If you are digiscoping through binoculars, mounting the binoculars on a tripod first creates a much steadier platform. The Muley Bino Adapter is designed to mount binoculars to a tripod for hands-free glassing.
MuleyCam With a Spotting Scope
A spotting scope is already commonly tripod-mounted, which makes it a natural platform for phone footage. Once the scope is aimed and focused, attach MuleyCam, align the phone camera, and make final focus adjustments while watching the phone screen.
Carrying MuleyCam in the Field
MuleyCam includes a carrying case that can attach to a belt loop or tripod leg, keeping the adapter accessible without leaving it loose in a pack.
Lifetime Warranty
MuleyCam is backed by a lifetime warranty. Like the rest of a hunting optics system, the adapter is intended to be used in the field, packed, carried, and set up repeatedly.
Is MuleyCam Right for Your Setup?
MuleyCam is a good fit if you want one phone adapter that can move between different phones, cases, binoculars, and spotting scopes rather than relying on a device-specific system.
