The GM H7R2 (model 740199-1) is Humminbird’s gimbal bracket for HELIX 7 Series units, letting you tilt the screen and remove the head unit with the knobs. It ships with the gimbal mount, knobs and mounting hardware, so it works as a spare or as a second mounting spot on another boat.

Good to know
- Confirm your unit is a HELIX 7 G4 or G4N, since other HELIX sizes use different brackets.

KayakDIY take: If you run one graph on two boats, a second gimbal is the simple way to move it without pulling hardware. For more on electronics, see my kayak fish finder guide.
