A quality lip gripper does two things that matter: it protects the fish by providing a secure hold without squeezing, and it protects you by keeping your fingers clear of hooks, teeth, and gill plates. A built-in scale adds a third function — accurate weight measurement without a separate tool. This guide covers the best options across both categories and explains what separates tools that work from tools that fail at the worst moment.
Lip Grippers: What to Look For
The core requirement is a grip mechanism that locks onto the lower jaw of a fish securely without applying crushing force. Spring-loaded T-bar grippers are the most common design — you squeeze the handle to open the jaws, insert the fish's lower lip, and release. The spring holds the jaws closed around the lip, suspending the fish vertically. Better grippers use a pistol-grip trigger mechanism that opens and closes with less hand force, which matters when you are handling a thrashing fish one-handed while managing a rod or net with the other.
Material determines longevity. Stainless steel grippers are the most durable and corrosion-resistant but add weight. Aluminum grippers are lighter and adequate for freshwater. Plastic-bodied grippers with metal jaws are the lightest and cheapest but flex under heavy fish and tend to develop play in the pivot point after a season of use. For serious anglers, stainless steel or machined aluminum is worth the premium over plastic.
For catch-and-release fishing, the gripper should support the fish vertically with minimal jaw stress. Large fish (over five pounds for bass, over ten pounds for saltwater species) should be supported under the belly with your other hand rather than suspended entirely by the lip — hanging a heavy fish vertically by its jaw can damage the jaw structure and reduce the fish's ability to feed after release. The gripper is a control tool first and a lifting tool second.
Boga Grip
30 lb capacity, stainless steel, mechanical scale, trigger-lock mechanism, 360-degree swivel, lanyard
The gold standard for lip grippers with a built-in mechanical scale. The trigger-lock mechanism secures the grip without constant hand pressure, and the 360-degree swivel lets the fish rotate without torquing the jaw. The integrated mechanical scale is accurate to within a few ounces and does not require batteries. Stainless steel construction is effectively corrosion-proof. The Boga is the gripper that tournament anglers and fishing guides rely on when accurate weight matters.
Piscifun Fish Gripper
55 lb capacity, aluminum body, T-bar grip, non-slip handle, lanyard and holster
A solid budget gripper that performs above its price point. The aluminum body resists corrosion in both fresh and saltwater, the T-bar grip locks securely, and the non-slip handle provides control with wet hands. No built-in scale, so pair it with a separate digital scale for weight measurement.
KastKing Waterproof Floating Digital Scale
110 lb capacity, digital LCD, waterproof, floating body, memory function, ruler on body
A dedicated digital scale that covers the weight measurement gap for grippers without built-in scales. The waterproof floating design survives drops overboard, the LCD is readable in sunlight, and the memory function stores the heaviest weight for later reference. The ruler printed on the body provides quick length measurement without carrying a separate measuring board.
Rapala Digital Fish Scale
50 lb capacity, digital LCD, memory function, compact folding design, includes culling beam
Rapala's scale has been a tournament standard for years. The folding design fits in a pocket, the digital display is large and accurate, and the included culling beam makes tournament bag management straightforward. Accurate to fractions of an ounce at weights relevant to bass and walleye tournament fishing.

Catch-and-Release Best Practices
How you handle a fish matters more than which gripper you use. Minimize air exposure — every second out of water increases stress and mortality risk. Wet your hands or the gripper jaws before contact to protect the fish's slime coat, which is its primary defense against infection. Support heavy fish horizontally under the belly rather than hanging them vertically by the jaw alone. If you are photographing a fish, have the camera ready before lifting the fish from the water, take the photo quickly, and return the fish immediately. Hold the fish facing into current or gently move it forward and back in still water until it swims away under its own power.
Lip grippers are better for catch-and-release than bare-handing in most situations because they provide a secure hold with less physical contact — less slime coat disruption, less squeezing, and faster release. The exception is very small fish (panfish, small trout) where the gripper jaws are disproportionately large for the fish's mouth — in those cases, gentle wet-hand handling is safer.
The Bottom Line
Pair a Piscifun gripper (budget) or Boga Grip (premium) with a KastKing or Rapala digital scale for the most versatile fish-handling setup. If you want a single tool that grips and weighs, the Boga Grip is the only serious option — its mechanical scale is accurate, reliable, and never needs batteries.
Scale Calibration and Accuracy
Digital fish scales drift over time, particularly after impacts, temperature extremes, and battery degradation. Calibrate your scale periodically by weighing a known object — a sealed bottle of water, a dumbbell, or any item with a verified weight. If the scale reads more than a few percent off the known weight, most digital scales have a calibration function accessible through a button combination (check the manual). If the scale cannot be calibrated, replace it — an inaccurate scale is worse than no scale because it gives you false confidence in your numbers.
Battery condition directly affects digital scale accuracy. As batteries drain, the voltage drops and readings become erratic — first slightly high, then unpredictably variable. Replace batteries at the first sign of dim display or inconsistent readings, even if the scale still powers on. For tournament use, carry fresh spare batteries in your tackle bag. The cost of two AA batteries is negligible compared to the cost of losing a tournament because a dying scale read your fish a quarter-pound lighter than reality.
Temperature affects digital scale accuracy too. Most digital fishing scales are calibrated for use in moderate temperatures (roughly 40 to 100 degrees Fahrenheit). Extreme cold can cause LCD displays to respond slowly and readings to drift. Extreme heat can cause internal components to expand slightly, affecting calibration. If you fish in temperature extremes, verify your scale's accuracy with a known weight before relying on it for tournament or personal-record weigh-ins.
Gripper Maintenance
Lip grippers with mechanical components — springs, pivot points, lock mechanisms — need periodic attention to maintain smooth operation. Rinse the gripper with fresh water after every trip, paying particular attention to the jaw pivot and any spring mechanisms where salt, sand, and debris accumulate. Apply a drop of corrosion-inhibiting lubricant (reel oil works perfectly) to the pivot point after rinsing. For the Boga Grip's mechanical scale mechanism, occasional lubrication of the internal spring keeps readings accurate and the trigger mechanism smooth.
Inspect jaw surfaces for wear. The serrated or textured grip surfaces on quality lip grippers wear smooth over heavy use, reducing their grip security. Most grippers cannot have their jaw surfaces restored — when the grip deteriorates to the point where fish slip, the tool needs replacement. Stainless steel jaws last the longest, followed by aluminum, with plastic-bodied tools wearing fastest. This is the primary argument for investing in a stainless steel or machined aluminum gripper from the start — the jaw surfaces outlast the cheaper alternatives by years.
Frequently Asked Questions
Do I need a lip gripper for fishing?
A lip gripper is not essential for small fish, but it significantly improves handling safety and fish welfare for bass, walleye, pike, and saltwater species. It protects your fingers from hooks and teeth while providing a more secure hold than bare hands.
Is it bad to hold a fish by the lip?
Holding a fish vertically by the lip is acceptable for fish under a few pounds. For heavier fish, support the belly with your other hand to prevent jaw damage. Never hold any fish by the lip at a horizontal angle with no belly support — the torque can dislocate or break the jaw.
What is the best fish scale for bass fishing?
The Rapala Digital Scale is the tournament standard — accurate, compact, and includes a culling beam. The KastKing Waterproof Scale is a strong budget alternative with a larger capacity and waterproof floating design.
How accurate are digital fish scales?
Quality digital fish scales from reputable brands are accurate to within fractions of an ounce at weights relevant to freshwater game fish. Calibrate periodically by weighing a known object, and replace batteries when the display dims or readings become erratic.
