SeaQualizer Descending Device for Fish Conservation

The SeaQualizer Descending Device reverses barotrauma symptoms in fish caught at significant depth. When reef fish like snapper and grouper come up from deep water, the pressure change causes their swim bladder to expand, making it impossible for them to swim back down on their own. The SeaQualizer clips to the fish's lip and descends them to a pre-set depth where it releases automatically via pressure activation. Three versions cover depths from 30 to 300 feet. Stainless steel and aluminum construction at $59.99. Also see the budget-friendly SeaQualizer SeaYaLater for a simpler option at $19.99.
  • Reverses barotrauma in deep-caught fish
  • Pressure-activated automatic release
  • Three versions: Shallow (30-70 ft), Standard (50-150 ft), Deep (100-300 ft)
  • Stainless steel and aluminum construction
  • Federally required in some South Atlantic waters

Best UV Sea Witch hair available. Measure out the hair on scale prior to tying. That way it is balanced out. Capt. Ryan Van Fleet Good Karma Sportfishing-Florida Keys. Wahoo love this stuff.

Perfect measurements and weight

Used this differently than its intended design. I made raft oars counter balances from them. Previously used steel 4lb mounted on the exterior near the grips. These I was able to install into the shaft and at 5lbs was able to get the weight away from the grips. Both oars took about 30 minutes. Another bonus is the seller got the weights to me in 4 days vice 12 Amazon predicted.

great bonito bait

Used these jigs this week and crushed the bonito on the east coast. This is a good bait to mimic the small bait fish in our area. Also great pack for a 2 pack. I bought a few different colors.

Awesome bait for Hybrid striped Bass.

Purchased these and first trip out boated several very nice Hybrids. The fish were in 5-7lb range. The bait falls fast and the hooks are very sharp for solid hook ups. Glad I had an extra one because I gave it to my buddy in the boat and he immediately hooked up. These baits worked so well, I ordered several more. I also referred several of my friends to the site to order this bait.

Quick delivery, great service

I live six hours from my boat in Swansboro and want my gear perfect when I step onto it a few times a month. I’ve counted on TheTackleRoom for many years to make sure I get what I need, when I need it before I head to the coast, and they have always delivered. I just received another order and am glad the level of service has stayed top notch.

Give Released Fish a Real Chance at Survival

Throwing back a bloated snapper or grouper that floats belly-up on the surface is not a release. That fish is going to die. Barotrauma - the expansion of the swim bladder from rapid pressure change - prevents deep-water fish from swimming back down. The SeaQualizer solves this by physically returning the fish to a depth where the pressure re-compresses the bladder and the fish can swim off under its own power.

The device clips to the fish's lower jaw. As you lower it on your fishing rod, water pressure increases. At the pre-set depth, the device automatically releases the fish. The fish swims away healthy instead of floating on the surface for birds to eat. As of July 2020, a descending device is federally required in South Atlantic waters for bottom fishing. Even where not required, using one is the right thing to do for the fishery.

Pressure-Activated Release

The SeaQualizer uses water pressure to trigger automatic release at your pre-set depth. You do not need to jerk the rod or pull a string. The device does the work. This means the fish is released at the correct depth every time, not wherever you happen to feel the release.

Three Depth Versions

Shallow releases fish at 30, 50, or 70 feet for nearshore reef species. Standard handles 50, 100, or 150 feet for mid-depth bottom fishing. Deep covers 100, 200, or 300 feet for deep drop applications. Each unit has three adjustable settings so you can match the depth the fish was caught.

Stainless Steel and Aluminum Build

Saltwater and depth pressure demand tough materials. The stainless steel clip and aluminum body resist corrosion and handle the forces of repeated descents. This is not disposable equipment. One SeaQualizer lasts for hundreds of releases with basic freshwater rinsing.

How to Use the SeaQualizer Descending Device

1. Set the release depth on the SeaQualizer to match the depth the fish was caught (or close to it)

2. Clip the device to the fish's lower jaw using the stainless steel clip

3. Lower the fish over the side and let it descend on your rod and reel

4. The device releases automatically when water pressure matches the set depth

5. Reel the empty device back up and prepare for the next fish

6. Rinse the device with fresh water at the end of the trip

Which version do I need? +
Match the version to your fishing depth. Shallow (30-70 ft) for nearshore reefs. Standard (50-150 ft) for typical bottom fishing. Deep (100-300 ft) for deep dropping. If you fish multiple depths, Standard covers the widest range. Our bottom fishing guide covers depth selection.
Is a descending device required by law? +
As of July 2020, a descending device or venting tool is federally required in South Atlantic waters for bottom fishing. Check current regulations for your area. Even where not required, using one improves fish survival. See our red snapper guide for release requirements.
How is this different from the SeaYaLater? +
The SeaQualizer has pressure-activated automatic release and three adjustable depth settings. The SeaYaLater is a simpler inverted hook design at $19.99 that requires a weight. The SeaQualizer is more precise; the SeaYaLater is more affordable.
Does it hurt the fish? +
The clip attaches to the lower jaw, similar to a hook hold. The fish is released at depth within seconds. Studies show descended fish have significantly higher survival rates than surface-released fish with barotrauma. Our grouper guide covers catch-and-release best practices.
What species need descending? +
Any reef fish caught from 30+ feet can suffer barotrauma. Red snapper, grouper, sea bass, vermillion snapper, and triggerfish are the most common. Our red snapper guide and grouper guide cover species-specific release tactics.
How long does the device last? +
With freshwater rinsing after each trip, the stainless steel and aluminum construction lasts for hundreds of descents. Inspect the jaw clip and pressure mechanism before each trip. At $59.99, it is a long-term investment in fish conservation. Browse our bottom fishing guide for more gear recommendations.
