Overview

The Garmin 010-11855-00 is a backpack tether that keeps a compatible handheld GPS where you can reach it fast when your hands are busy. The nylon harness wrap secures with hook-and-loop around straps up to 3.75 inches wide and it can also attach to MOLLE webbing.

A spine mount holds the device, and an adjustable lanyard cord (2 to 14 inches) keeps it with you when you pull the handheld off the strap to check position, drop a waypoint, or confirm your track.

On board, this is a practical way to carry a handheld as a backup navigator in the cockpit, on a PFD strap, or on a deck bag when you are moving around in spray and want the unit to stay attached.

Key features

• Nylon harness wrap with hook-and-loop closure fits straps up to 3.75 inches wide
• MOLLE compatible for packs and webbing systems
• Spine mount interface for Garmin handhelds that use the spine mounting system
• Adjustable lanyard cord from 2 to 14 inches for retention while the device is in hand
• Hook-and-loop stow position keeps the handheld parked on the strap for quick access

Compatibility and fit

Fit comes down to the strap you are mounting to and whether your handheld uses the Garmin spine mount system. The wrap closes around most shoulder straps and harness-style straps up to 3.75 inches wide.

It works with many Garmin handheld families, including Dakota 10 and 20, eTrex 10, 20, and 30, GPSMAP 64 Series, and Oregon Series. It is also used with other GPSMAP handheld lines and inReach handhelds that share the same spine mount system; inReach Mini 2 requires an additional spine mount adapter.

Installation and on-board use

Wrap the harness around your chosen strap, press the hook-and-loop closed, then attach your handheld to the spine mount and set the lanyard length so it reaches comfortably without dangling into winches, rod holders, or running rigging. Placing it high on a shoulder strap or PFD strap keeps it easy to read and helps reduce snagging.

This setup is a good match for coastal cruisers, anglers, paddlers, and race crews who carry a handheld as a backup and want it accessible without digging through pockets or a dry bag.

Maintenance and care

After salt spray, rinse the tether with fresh water and let it air dry before storage. Periodically clear lint from the hook-and-loop and inspect the lanyard and attachment points for wear, especially if it sees regular UV exposure.
