The 1280X Aquanaut: Simple, Tough, Submersible to 250 Feet
The 1280X has been a beach- and water-hunter's standby for decades because it does the essentials and nothing it doesn't need to. It's submersible to a full 250 feet, so it handles wading, surf, lakes, and genuine scuba diving — not just the splash zone. Its single 2.4 kHz frequency runs deep and stable on high-conductivity targets like coins and rings, full-range discrimination lets you tune out iron and trash, and the whole machine is turn-on-and-go with no ground balancing to learn. The standout spec is battery life: up to 75 hours on AAs, so you're not babying a charge across a weekend of tides. It ships with submersible headphones and is built to take saltwater abuse. For divers and beach hunters who want a rugged, affordable, do-the-job water detector, the 1280X is the classic answer. Browse the rest of our deep waterproof detectors to compare.
1280X vs CZ-21 vs Impulse AQ: Which Fisher Water Detector?
Fisher makes three water machines at three levels. The 1280X is the simplest and most affordable: turn-on-and-go, submersible to 250 feet, single-frequency, basic discrimination — the budget diver's and beach-hunter's pick. The CZ-21 steps up to dual-frequency performance and 3-tone target ID, also dive-rated to 250 feet, for hunters who want to know what they've found underwater. The Impulse AQ is a pulse-induction specialist — only 3 feet waterproof (wading and surf, not diving) but unmatched on deep, small gold in black sand. In short: choose the 1280X for simple, rugged, affordable diving and beach hunting; the CZ-21 when you want target ID and dual-frequency depth underwater; the Impulse AQ for deep-gold surf prospecting.

Coils & Accessories for the 1280X
The 1280X comes in two coil configurations — the 10″ concentric coil for depth and coverage on open beach and water, and the 8″ concentric coil for handier swinging in tighter spots. When factory-new units are between restocks, open-box units of both are frequently available at a lower price, so check the listings. Round out the machine with a replacement armrest assembly or a spare Anderson carbon lower rod, and grab the free 1280X digital manual.
Fisher 1280X FAQs
How deep can the Fisher 1280X go — can I scuba dive with it?
Yes. The 1280X is submersible to 250 feet (76 meters), so it's a true diving detector as well as a beach, surf, and lake machine. It ships with submersible headphones, and at that rating it handles everything from the wash to deep dives.
How is the 1280X different from the CZ-21 and Impulse AQ?
The 1280X is the simplest and most affordable of Fisher's three water detectors — turn-on-and-go, single-frequency, dive-rated to 250 feet. The CZ-21 adds dual-frequency performance and 3-tone target ID (also dive-rated). The Impulse AQ is a pulse-induction machine, waterproof only to 3 feet, that reaches deeper on small gold in black sand. Pick the 1280X for simple, rugged, affordable diving and beach hunting.
Is the 1280X good for beginners?
Yes, for water hunting it's one of the easiest to learn — there's no ground balancing, just sensitivity and discrimination. That turn-on-and-go simplicity, plus its rugged build and long battery life, is a big part of why it's stayed popular for so long with beach and water hunters.
Does the 1280X work in saltwater?
Yes. It's built for salt and fresh water as well as dry land, and its low 2.4 kHz frequency stays stable on wet salt sand where many land detectors falter. It's a dedicated beach and water machine.
How long does the battery last?
Up to about 75 hours on AA batteries — one of the longest runtimes of any detector, which means you can hunt a full weekend of tides without swapping cells.
Should I get the 8″ or 10″ coil?
The 10-inch coil gives more depth and ground coverage and is the popular all-around choice for open beach and water; the 8-inch coil is handier in tighter or trashier spots. The 10-inch is the better default for most water hunters.
