On this page (4 sections)
The best dual fish finder mount for two displays on one support is the Millennium Marine Double Face Marine Electronic Mount, which can accommodate two 12 in monitors. For separate adjustable positions, the WINDFRD and RAM MOUNTS arms offer other ways to arrange a fish finder double mount setup.
Two screens can make sonar and chart information easier to view from one station, but the mount has to suit your console, screen sizes and fishing position. A wide dash bracket, two separate arms and a double-face monitor mount solve different layout problems.

WINDFRD Heavy Duty Fish Finder Mount: Best for large screens on a flat surface
- All-aluminum construction
- 360-degree swivel
- Supports screens over 10 in and up to 16 in
A heavy-duty all-metal mount with a 360-degree swivel gives you positioning flexibility for a large display. Its base is designed for flat surfaces such as dashboards, boat decks and kayaks.
Pros
- All-aluminum construction
- 360-degree swivel
- 316L stainless steel mounting kit included
Cons
- A single mount does not create a two-display face by itself
- Check the display and mounting plate fit
WINDFRD's Heavy Duty Fish Finder Mount is a strong option when one of your displays is large and needs a broad range of adjustment. The all-aluminum mount is designed for screens over 10 in and up to 16 in, and its arm swivels 360 degrees.
The mount's base is drilled for flat surfaces, including dashboards, boat decks and kayaks. That makes it useful as one part of a two-screen arrangement, though you would need a second compatible mount or another support for the other display.
A track base is another mounting approach; see fish finder track mounts.
WINDFRD includes a 316L marine-grade stainless steel mounting kit. The mount also uses powder-coated marine-grade aluminum and stainless steel hardware for saltwater environments.
Choose it when a large screen needs its own adjustable position. Before buying, compare your display's mounting pattern and the room available for the base and arm.
To help secure a display when the boat is unattended, compare fish finder locks.
RAM MOUNTS Heavy-Duty Fish Finder Mount: Best for flexible positioning
- Near-infinite adjustment with ball and socket
- Marine-grade aluminum
- Overall height of 8.125 in
This drill-down mount uses a ball and socket system for broad positioning flexibility. Consider it when each display needs its own mount and the surface can accept a drilled base.
Pros
- Near-infinite adjustability
- Shock and vibration isolation
- Marine-grade aluminum
Cons
- A single mount holds one device
- Check compatibility with each display
The RAM MOUNTS Heavy-Duty Fish Finder Mount uses a ball and socket system for near-infinite adjustment. At 8.125 in overall height, it can help place one screen where it remains visible alongside another separately mounted display.
RAM MOUNTS describes its ball and socket design as isolating and dampening shock and vibration. Its base is designed to drill into a flat surface, and its construction combines marine-grade aluminum with high-strength composite.
For a two-screen setup, plan on a mount for each display unless you already have a separate bracket that carries the second one. Compare the base position and arm reach with your console before drilling.
This is a useful choice when you want to angle displays separately. For an all-aluminum option, see our best aluminum fish finder mount guide.
RAM MOUNTS Fish Finder Mount for Humminbird: Best for select Humminbird displays
- Fits Humminbird Helix 8, 9 and 10, and Solix 10
- Includes round and rectangular bases
- Ball and socket adjustment
This model-specific mount fits listed Humminbird displays and includes a short double socket arm. Use two compatible mounts if your setup needs independent positioning for two screens.
Pros
- Display-specific fit for listed Humminbird models
- Two mounting bases included
- Near-infinite adjustability
Cons
- Compatibility is limited to listed models
- A single set is for one display
This RAM MOUNTS model is designed for select Humminbird Helix and Solix screens. It fits the Helix 8, 9 and 10, and Solix 10, with a short D-size double socket arm and two bases included.
The rectangular base connects to the marine electronics, while the round base mounts to a flat surface. Ball and socket adjustment lets you position the screen, which can help when you are arranging it near a second display.
Its compatibility is specific, so check your exact Humminbird model before choosing it. If your second display has a different mounting pattern, plan its bracket separately.
Millennium Marine Double Face Marine Electronic Mount: Best for two monitors on one mount
- Accommodates two 12 in monitors
- Height adjusts from 18 to 24 in
- Base swivels 180 degrees and face plate 350 degrees
This double-face mount is designed to accommodate two 12 in monitors on one adjustable setup. The telescoping riser and swivel points help position screens for your boat layout.
Pros
- Designed for two monitors
- Adjustable height
- Anodized aluminum with stainless steel hardware
Cons
- Confirm your display plate fit before buying
- Requires room for an 18 to 24 in riser
The Millennium Marine Double Face Marine Electronic Mount is the most direct match for a double fish finder mount because it can accommodate two 12 in monitors. Its telescoping riser adjusts from 18 to 24 in, giving you a way to set the screens at a useful height.
The base swivels 180 degrees, and the monitor face plate swivels 350 degrees. This range can help you turn the displays toward a driver or another fishing position, depending on where the mount is installed.
The mount uses anodized aluminum and includes heavy-duty stainless steel hardware. Millennium Marine describes the face plate as a near-universal design for most current marine electronics, but check your screen's fit and mounting pattern before you commit to the setup.
Choose this option if you want both displays carried by one support. If each screen needs a separate angle or height, individual adjustable arms may give you more control.
PROcise Outdoors Dual Dash Mount: Best for a long console span
- 24.75 in long
- 3/16 in thick aluminum
- Pre-drilled holes for multiple brands
This long aluminum dual dash mount suits a flat-faced console where screens need space across the dash. Its pre-drilled holes support multiple brands, with room to drill additional holes if needed.
Pros
- 24.75 in long
- Designed for Humminbird, Lowrance and Garmin screens
- Pre-drilled holes for multiple brands
Cons
- Needs a flat-faced console
- Measure the console and screen spacing first
The PROcise Outdoors Dual Dash Mount gives you a 24.75 in span across a flat-faced console. For Lowrance units with navigation, see Lowrance fish finders with GPS.
Its 3/16 in thick aluminum body has pre-drilled holes for multiple brands, and the mount is designed for Humminbird, Lowrance and Garmin screens.
This long bracket can help keep two displays side by side without placing each on a separate arm. PROcise says the layout can reduce wire stress and improve visibility, but fit still depends on your console and display positions.
Measure the usable dash width and map the screen footprints before installation. The mount allows additional holes to be drilled when needed, so confirm the layout and cable paths first.
How do you choose a fish finder double mount?
Choose by how the displays attach and move: a double-face mount carries two monitors, a long dash mount spans a console, and separate arms give each screen its own adjustment. The right choice is the one that keeps both screens readable without crowding controls or sightlines.
Will the mount fit both displays?
Check the mounting pattern and the screen size for each device. The Millennium Marine model accommodates two 12 in monitors, while WINDFRD's single mount is designed for screens over 10 in and up to 16 in.
For brand-specific fit, the RAM MOUNTS model here is designed for select Humminbird screens. If you are comparing another support style, our best fish finder gimbal mount guide covers gimbal-style options.
Does the mount give you enough adjustment?
A swiveling face can turn both monitors together, while two separate arms can let you adjust each display on its own. The Millennium Marine mount has a 180-degree swivel base and a 350-degree swivel face plate; the WINDFRD arm swivels 360 degrees.
Think about where you'll stand or sit while fishing, then check whether you can see both displays from that position. Our best adjustable fish finder mount guide can help you compare options when angle changes matter.
Will the console support the base?
Measure the flat mounting area, including room for screws, cables and the full screen footprint. A long console bracket needs enough usable width, while drill-down bases need a clear area where they can be secured.
Consider how each screen will sit beside other controls. Leave room for cable slack and for moving or swiveling the screens without hitting the wheel, throttle or other equipment.
How do dual sonar terms differ from a dual display mount?
A dual fish finder mount holds two displays, while dual frequency and dual beam describe sonar features. These terms sound similar, but they answer different buying questions.
A dual-frequency fish finder can use two sonar frequencies from one display. Read our Dual Frequency Fish Finder: A Quick Guide if you want to understand how frequency relates to sonar use.
A dual-beam fish finder uses a transducer beam pattern to cover an area beneath the boat. Our Dual Beam Fish Finder: A Beginner’s Guide explains the distinction between beam coverage and two separate screens.
Which double fish finder mount should you choose?
Choose the Millennium Marine Double Face Marine Electronic Mount when you want one assembly designed for two monitors up to 12 in. Pick the PROcise Outdoors Dual Dash Mount for a long flat console span, or use separate adjustable mounts when you want to position the screens independently.
Before installation, verify both display mounting patterns, measure the console and plan cable routing. That simple fit check helps keep the two displays stable, visible and clear of nearby controls.

Frequently asked questions
What is a dual fish finder mount?
A dual fish finder mount holds two sonar displays together or supports two separate mounts on one console. A double-face monitor mount is designed for two screens, while a long dash mount or two individual arms can position separate displays across the boat.
Check screen size, base placement and viewing angles before choosing.
Can one fish finder mount hold two displays?
Some mounts are designed for two monitors, such as the Millennium Marine Double Face Marine Electronic Mount, which can accommodate two 12 in monitors. Most adjustable arms in this group are single-device mounts, so a two-screen setup may need two bases.
Confirm the mounting plate fit for both screens.
How should I position two sonar displays?
Place both screens where you can read them from your normal fishing position without blocking controls or your view ahead. Leave enough room to adjust each screen and keep cables from pulling as the displays move.
A swiveling face or adjustable arm can help you set a useful angle.
Does dual frequency mean two fish finder screens?
No. Dual frequency describes sonar operating at two frequencies, while a dual fish finder mount is a physical support for two displays.
One screen may use more than one sonar frequency without needing a second display.
Our Dual Frequency Fish Finder: A Quick Guide explains the sonar term.
What should I check before installing a double fish finder mount?
Measure the flat mounting area, screen width and height, and the space needed for cables and adjustment. Check the display's mounting pattern and make sure the two screens won't block controls or each other's sightline.
For beam terminology, see our Dual Beam Fish Finder: A Beginner’s Guide.
