Quick take

A NOAA-compliant reusable device that returns deep-caught fish to the seafloor with three depth settings.

The SeaQualizer Standard Release is the middle model of the line, built to lower a fish back to a set depth after it comes up from deep water. Its pressure-activated release opens the clip on its own at 50, 100 or 150 feet, so you choose one of three presets before you drop it. The jaw clip is stainless steel, and the body is stainless steel and aluminum. Sitting between the 30 to 70 foot Shallow and the 100 to 300 foot Deep versions, it covers the 50 to 150 foot range where most bottom fishing happens.

Best for

  • Saltwater bottom fishing in deep water
  • Catch and release in federal waters with barotrauma concerns
  • Charter captains and conservation-minded anglers

Skip if

  • You keep all your fish for the table
  • You fish shallow water where barotrauma is not a concern

Strengths

  • Three adjustable depth settings release fish at the correct pressure
  • Marine-grade stainless steel and toughened plastic ensure durability
  • Non-invasive design avoids injuring the fish and does not require hook removal

Trade-offs

  • Only useful for saltwater; freshwater regulations vary
  • Requires a downrigger or manual lowering to use

Common questions

What depth does the SeaQualizer Standard Release set to?

The Standard Release has three preset release depths: 50, 100 and 150 feet. You pick one setting before lowering the fish. The pressure-activated clip stays closed until the device reaches that depth, then opens on its own, so the fish swims free at the depth you chose.

Which SeaQualizer should I use for fish caught at 200 feet?

The Standard Release tops out at a 150 foot setting, so it does not fit fish caught at 200 feet. That depth falls in the Deep version's 100, 200 and 300 foot settings. The Standard suits bottom fish from about 50 to 150 feet, and the Shallow model covers reef fish from 30 to 70 feet.

What is the SeaQualizer Standard Release made of?

The Standard Release has a stainless steel and aluminum body and a stainless steel jaw clip. Its model number is 5133-0001. The release depth is set by a pressure-activated mechanism that you choose before the descent.
