Mounting Hardware
Our range of mounting accessories are engineered to withstand the harshest marine environments, ensuring long-term durability, corrosion resistance, and secure equipment mounting. Designed for quick deployment,our hardware offers seamless installation and trusted performance when it matters most.

Built for salt water
Solid aluminium with a hard-anodised finish and stainless steel hardware, made for the harshest marine environments and years of use.
Fits almost any gunwale
The tilt adjustable Universal Gunwale Bracket clamps on with two screws, with soft bump stops to protect the boat and extension kits for wide gunwales.
Light for small craft
The 5/8″ Survey Pole Series suits kayaks and small boats, with a thumb release to swing the pole up and a thread that takes the GNSS antenna directly.
Heavy duty when it counts
The 50 mm / 2″ Tube Series adds stiffness for heavier transducers, with brackets for every CEE transducer plus UHF, IMU and side scan.
From kayaks to survey vessels.
Quick to deploy, simple to install and trusted to hold your transducer steady when it matters most.
Kayaks & canoes
Light weight 5/8″ survey poles suit a variety of small water craft.
Small open boats
Clamp to the gunwale in minutes with the tilt adjustable Universal Gunwale Bracket.
Inflatables & RIBs
A thumb release swings the pole from vertical to horizontal when entering and exiting the water.
Dedicated survey vessels
Heavy duty 50 mm / 2″ tube assemblies for heavier transducers and demanding conditions.
GNSS & UHF antennas
5/8″ threads take the GNSS antenna directly, with a UHF bracket for CEESCOPE™ RTK models.
Side scan & IMU
Deploy a StarFish side scan sonar or SBG Ellipse IMU on the transducer pole.
Proven on real surveys
Two pole systems, one secure mount
A light 5/8″ survey pole for small craft in fresh water, or a stiff 50 mm / 2″ tube for heavier transducers, built to last in salt water.

Universal Gunwale Bracket
A tilt adjustable bracket that securely mounts a 50 mm / 2″ pole to a boat’s gunwale. Soft urethane bump stops protect the boat, and two clamp screws give a secure, hassle-free set-up.
Product Options
Start with the gunwale bracket, then choose a pole series, add-ons and a transit case.
Mount to any gunwale
A tilt adjustable bracket for a 50 mm / 2″ pole, with a 60 mm / 3.9″ opening as standard.

How wide is your gunwale?
Extend the opening of the Universal Gunwale Bracket up to 250 mm / 9.8″. Aluminium and stainless steel construction for stability.



Small boat mounting hardware

Shallow river survey from an inflatable raft with the CEE-LINE™ and Trimble TSC7
Engineering firm Midwest surveyed the remote, braided Red Deer River in Alberta and Saskatchewan by adding a CEE-LINE™ echo sounder to its Trimble R12i and TSC7 setup and paddling it on an inflatable raft. The survey, with depths often just inches below the transducer, produced a 3D elevation model for the client’s erosion and asset protection work.

Blue Arc Engineering halves fieldwork on dock permit surveys with the CEE ECHO™ and Hydromagic
Blue Arc Engineering in Fort Myers, Florida swapped manual range pole and GNSS depth surveys for a CEE ECHO™ with Hydromagic and its existing Trimble R780. Fieldwork that would have taken a full day was cut in half, and the bathymetric product followed within days.

CEE-LINE™ for trustworthy shallow water bridge scour surveys in Germany
After several basic pole mounted echo sounders fell short, Ingenieurbüro Saam GmbH in Upper Bavaria adopted the CEE-LINE™ for bridge scour and river surveys in the Trimble Access environment. Datasets were consistent, repeatable and trustworthy, with consistent depths in very shallow water even near bridge structures.

CEESCOPE™ flyaway kit used for a dam survey in South America
After two days of training, a transport engineer ran his first survey in South America two weeks after receiving the CEESCOPE™. The all-in-one echo sounder and Hydromagic made a successful reconnaissance dam survey simple, with the kit hand carried on the airline.

CEESCOPE™ and enhanced StarFish side scan for rapid mobilization surveys with the Royal Australian Navy
The RAN now has a ruggedized, airline-portable Rapid Mobilization Survey System (RMSS), a CEESCOPE™ with Tactical StarFish side scan, for rapid environmental assessment, vessel of opportunity and conventional survey ship work, all acquired in HYPACK®.

CEESCOPE™ gives Canada Pump and Power easy pre-dredge surveys of Alberta effluent ponds
With no echo sounding experience and a tight deadline, Canada Pump and Power used a 33/200 kHz all-in-one CEESCOPE™ to complete urgent pre-dredge surveys of several Alberta tar sands effluent ponds. Pond sludge and water volumes were delivered on time, and CPP now runs Hydromagic in real time on later projects.
