Fisher 55" Extended Lower Tube for Impulse AQ NiMH Metal Detector

Description

Add extra shaft reach to your Fisher Impulse AQ NiMH metal detector with the Fisher 55" Extended Lower Tube Assembly.

Designed specifically for the Impulse AQ NiMH configuration, this extended lower shaft measures 55 inches and provides additional detector length compared with the standard lower tube. It is a purpose-built shaft component for users who need a longer setup for their detecting style or body height.

Key Features

• 55" Extended Lower Tube – Provides substantially more shaft reach than the standard lower tube.

• Designed for Fisher Impulse AQ NiMH – Built for the matching Impulse AQ detector configuration.

• Extended Shaft Reach – Useful for users who need a longer detector setup.

• Replacement / Alternate Shaft Component – Can be used as an extended lower-shaft option for the compatible detector.

• Fisher Labs Accessory – Sold specifically as a Fisher Impulse AQ shaft component.

• Purpose-Built Fit – Designed for the matching Impulse AQ assembly rather than universal detector use.

Designed for the Fisher Impulse AQ NiMH

This lower tube is intended for the:

Fisher Impulse AQ NiMH Metal Detector

The current First Texas Impulse AQ Limited uses the IMPULSE-AQ-NMH configuration with a rechargeable NiMH power system.

This extended shaft should therefore be treated as an Impulse AQ-specific component, not as a universal Fisher lower stem.

55" Extended Design

The defining feature of this part is its 55-inch length.

The retailer states:

“The extended lower shaft is 55".”

That makes it significantly longer than the standard 30" TUBE-AQ lower tube we identified previously.

The additional length can be useful for detectorists who:

• Need greater overall shaft reach

• Prefer a longer detecting configuration

• Have a taller body frame

• Want more distance between the control assembly and search coil

• Need an alternate shaft setup for specific detecting conditions

Extended Reach for Comfortable Setup

Detector shaft length affects ergonomics and sweep position.

A shaft that is too short can force the user to bend or shorten the sweep unnecessarily.

The extended 55" lower tube provides additional adjustment potential for users who prefer a longer configuration.

Actual comfort will depend on the complete detector setup and individual user height.

Replacement or Alternate Lower Shaft

The extended tube can serve as:

• A replacement extended shaft

• An alternate shaft configuration

• A spare extended lower tube

• A dedicated shaft for a preferred Impulse AQ setup

Because it is specifically built for the Impulse AQ platform, it provides a cleaner fitment option than attempting to adapt a generic detector shaft.

Standard vs. Extended Impulse AQ Lower Tube

There are two separate lower-tube products we have now identified:

The extended version should be kept as a completely separate Detector Warehouse SKU and product page.

Why Choose the Fisher 55" Extended Lower Tube?

The Fisher Impulse AQ is a specialized detector, and shaft fit can make a noticeable difference in handling and comfort.

This extended lower tube increases the shaft reach to 55 inches, giving Impulse AQ NiMH users a longer setup option than the standard tube.

For taller users or anyone who prefers a longer shaft configuration, it provides a purpose-built Fisher-compatible solution without relying on a universal aftermarket stem.
