description says warerproof, but are they saltwater proof?

Answer: Hi there,

Answer: waterproof yes but with eventual saltwater corrosion nothing is saltwater proof lol.

Answer: Definitely NOT waterproof. Stored them on my boat and just the residual moisture made the unit crap out in exactly 1 year. Terrible quality.

Answer: Yes, it does tare.

Answer: It does

Answer: 0-50 pounds.

Answer: 0-50 lbs.

any online instructions for this thing?

Answer: Same problem. Looked extensively for instructions..Couldn't get the thing to work properly, so returned it.

Answer: Mine came with a small card in it, with limited instructions.

Answer: No

I bought this handheld weighing scale is there a way to calibrate the scales they are haft pound

Answer: Yes. Reset to zero.

Can this scale be calibrated?

Answer: Yes.

Does Kastking offer a warrenty on this scale? The first time it hit the water it died and I'm 2 weeks out of the amazon return window.

Answer: I think it's a year warranty. You would need to contact Kastking. Check the battery first.

Do the grippers float?

Answer: Hello,

Answer: Can’t tell you if they float but they are very small and won’t hold a decent sized fish I threw them away. The scale is nice though!

Answer: Yes they absolutely float..

Answer: Yes they do

can the lip grabber hold 50 lbs?

Answer: I would think so. Never caught a 50 pounder but this scale has a grabber that locks so it should hold it

Answer: Hi Scott,

Does this scale weigh in decimals?

Answer: Hi rondot,

Answer: No it weighs in pounds and ounces. no decimals

Answer: Yes it measures 10ths and 100ths

Answer: Yes, it does.

How big are the lip grips?

Answer: The gripper portion is 9-10 inches long and 1/2 inch wide. I haven't damaged any fish using mine. The scale portion (with hook) is about the same length. Use the lanyard to attach the 2 pieces and it comes out to about 2 foot long. BTW, I weighed some metal weights when I got it and found it very accurate at 5 and 10 pounds.

Answer: We lake fish and catch bass and the grips are sufficient.

Answer: I do not have a size spec, but it worked with a 13 lb catfish I caught

Answer: I use these for Large mouth bass and they work great. If you are wanting to know if they would work on a pike or musky, the answer is no, I do not think so.

Does this scale give the total combined weight of your fish?

Answer: Nope

Will the grippers hold a 30lb catfish?

Answer: I don't think so.

Has anyone tested the accuracy of this scale yet ?

Answer: 0-50 lbs.

Warranty? bought 10/30/19. it failed nov. 2020. battery still good, changed anyway. doesn't turn on. accuracy was good while alive..

Answer: Sadly, throw it away. I had the same issue, worked great for about one tournament then just died. I then bought the Rapala 15lb digital tournament scale and swapped the clip for the small Ardent gripper clamp. I have a full year on that rig, dropped it in my live well at least once, baked it in the sun, and left it in the rain...and my weights are still spot on with the weigh-in results.

Answer: I would reach out to KastKing customer service directly.

What size batteries does it take?

Answer: It takes a quarter sized watch battery, sorry dont know the exact size

Answer: CR2032

Will this hold a large catfish?

Answer: I guess it depends on what you call large. I have weighed King Salmon up to 25lbs on mine.

Answer: The scale and the gripper are both rated for up to 50 pounds. To use them together, you may need to swap out the split ring on the gripper handle. In testing mine, I connected the gripper to a 10 pound object and then connected it to the scale. As soon as I lifted, the split ring pulled apart. I replaced it with a sturdier one from an old key ring.

Answer: I’ve held up to 30 pounds several times. I’m fairly certain it would

Does it tare?

Answer: Yes, it does.

Answer: Yes, it does tare.

Answer: It does

Product reviews of KastKing Waterproof Floating Digital Fishing Scale with No-Puncture Lip Gripper. Dual Mode - Pounds/Ounces & Kilograms. 0-50 Lbs/22.68 Kg, Lightweight ABS Frame, Non-Slip Handle.

Jon N. : One of the best fish scales on the market

Great fish scale at a reasonable price. It was perfectly accurate right out of the package. I dropped it off my kayak into the water and it floated fine and appears to have no water intrusion. Also the fish grippers work great and hold the fish with no problems.

Castle : Kastking combo

Nice combo that every fisherman needs in there gear bag. The scale can be a little bit hard to set up but still nice and the grips are nice.

Amazon Customer : Buy something else

Looks like a little water got inside and shorted it out. Not happy

Marc : find your PB

good little tool to have the the fishing bag. great way to keep track of your personal record fish, as the scale is accurate to within a few ounces as tested by a known weight. the plastic clamp feels a little light, but so far has worked great. if i can get a year's worth of fishing and weighing out of it, it will have been more than worth it.

Kindle Customer : Easy to read

Easy to hold and read. Being waterproof is great in a kayak. Bold color makes for a faster find and grab. The grabber is also easy to hold onto and work great.

Steve Moore : Good scale

Love this product. Have used it on several trips out on my boat. Seems accurate when I tested it with calibrating weights. Product appears to be well made too. A quality, product that is constructed well and does what it is supposed to do... All at a fair price point. What more could one ask for?

Seth L : Kayak fishing must have

Perfect light weight setup. Love the fact it floats and that it comes with the lip clamp. Perfect for my kayaking setup.

Bryan : Nice when it works —but when does it work?

I bought this to use kayak fishing. I like that it is waterproof and that it floats just in case.

Other than that I've had nothing but problems with it. Maybe I have a defective unit.

The battery is constantly dead. Not sure whether it has an auto-off, but it definitely needs one - and a feature to keep it from accidentally turning on when resting in a bag. Again, if it has these features, they need to be improved because they don't work.

I've never had more than one day of use, only to grab it the next time out and have it not work.

I just replaced the battery this weekend. Had one good day of use. I even packed spare batteries in my tackle box. Two days later I go to use it - nothing. Won't turn on. I replace the battery on the spot. Still won't turn on.

Very disappointed. Sadly, when I search for a scale with the features I want - this is what keeps showing up. I see others with positive reviews. Maybe mine is a dud.

Not sure I want to risk it on another one. So frustrating.

Kyle kroft : Highly recommend

Very very very good scale. Easy to carry, easy to operate. I really like the clasp for holding the fish. Very easy to operate

---------------------------- : Great scale

I beleive this is the best out there. For sure is the best one that Ive ever owned.

Kyle kroft : Highly recommend

Very very very good scale. Easy to carry, easy to operate. I really like the clasp for holding the fish. Very easy to operate

Steve Sheffield : Not dependable enough for tournament use

I rarely leave bad reviews , however......I found this scale to be very inconsistent. After depending on it for culling fish in tournaments, I eventually tested it against multiple friends’ scales. We found this scale was generally low by as much as a pound while the other 3 scales were within 2 Oz of each other. I tried calibrating it but then found there was no consistency. The same fish would weigh differently upon subsequent attempts. I read other reviews related to battery usage. I changed the batteries and that did seem to be related to my issue. However, that is unacceptable. The fish weight shouldn’t be related to the strength of the battery
Very disappointing.

Eric Fisher : Works like a charm

Love all my Last king products and this combo didn't disappoint

JHill : Usability/look and feel

Just received my package. Initial observation is that it looks good, and easy to use after a quick review of the instructions. I expected the Lip Gripper to be larger, but it still feels functional. Materials feel rugged enough to last. Looking forward to trying it this coming weekend

Senyi Ly : Worked a few times but has since died

Worked for one month and a few trips out on the water. But now it won't power on and the power button feels like it keeps getting stuck. I know the battery couldn't have been drained as I've only used it a few times. Maybe the power button for stuck in the on position and drained the battery. Either way it shouldn't have that issue with only a few uses. Not sure who to contact for product support since I'm out of the return period.

Joel : Great scales

Worked great saved me lots of time not having to drive to the weigh in station on fish that were to close to call with out scales

Glenn : Good scale, lame grabber

I really like this scale, from it being waterproof to the "last 8 weights" memory. The grabbers are weak and slipped on a 4 pound fish. I would much rather they add a grabber clip to the scale in place of the gill hook and get rid of this useless add-on.

---------------------------- : Great scale

I beleive this is the best out there. For sure is the best one that Ive ever owned.

Shooter : Awesome!!

Works better than expected. Very pleased with the product. Holds fish tight on the clamp.

Steve Moore : Good scale

ando : died after before a year

brought this jan 6 th this year after light use with this scale it has stoped working the screen will not even show anything as u can see from pic . come on kastking this bad ill gues ill keep looking for something eles .

Driftin NC : Great price

Great product that’s easy to use and accurate the grips also do good

Dylan : Amazing products!!!

Amazing products, I can’t wait to use them. Very fast shipping.

Michael M. : Not worth it

did not work right out of the box. Tried to return but have to take to ups, nearest UPS to me is 50 miles away

Ryan : Great value/combo

The fish grippers work well and the scale gets the job done

Patrick : Not even close to waterproof

I had this scale to use while kayak fishing as it was advertised as waterproof and floatable. I mostly bought due to it being floatable as I would not have to necessarily tether it to the kayak. This product had not even gotten very wet and had never been submerged. Yet, the product became waterlogged and quit working for awhile. Now it is working but you can barely see the numbers. I would not recommend this item at all. I have had other scales that work much better than this one albeit for a higher price and they were not advertised as waterproof or floatable.

RT : Safe way to handle and weigh fish (for fish and angler)!

Used these a bunch of times to grab fish and weight them. Caught 4 catfish weighing over 4 pounds and a 3.5 lb large mouth bass in an hour and got to try out these grips and scale. They were easy to use, and none of the fish were harmed using them. It did take a little time to figure out how to hold it just right so they wouldn't slip off, but now it's second nature.

I ended up buying another set to keep in another tackle bag. I noticed that there was a slight gap between the gripper's arms, but it didn't seem to affect their use.

Amazon Customer : Buy something else

Looks like a little water got inside and shorted it out. Not happy

Gem : Works great, accurate, waterproof

Have had it in my fishing bag for a while now, and it works great. Battery is still at 100% and it weighs accurately both with and without the lip gripper.

Eric Fisher : Works like a charm

Love all my Last king products and this combo didn't disappoint

Steve Moore : Good scale

Keith N. : Last scale went to the bottom of the pond!

Seems pretty accurate - took some gym weights (5,10 lbs) and weighed them and they were spot on. Good to know that my "guesstimates" were pretty accurate too. It doesn't take up too much room in the kayak and now I can boast with accuracy about how big the bass are (HaHa). I feel like the lip gripper is much easier on the fish than the old style hook.

Jason : I like!

good product, very light but strong, very easy to use, it won't rust!

William H. Stoner : NO FISH, NO WEIGHT!!

Just as manufacturers says, leave it out of direct sunlight, reads good in a shadow, need to catch more bass to see how true the weight is. I like it!

JHill : Usability/look and feel

Miguel Melenciano : Uhhh? DIIIIINNNGGG!

It floats, its waterproof, it records your weights, and most important of all it works quickly and accurately under "flopping" conditions. So great to see this company master its craft before my very eyes. Everything I've gotten from kastking so far has been on the money. This scale is a keeper! Also you see the pic, close to a 6 pounder.. flopping like crazy.. The grippers didn't flinch once! Well done kastking..Well done!

@chartmypants : Not waterproof...

Bought for kayak fishing knowing it was going to get wet... seemed to hold up the first couple of times I took it out but when I went to use it today after having it for about two weeks there was water behind the screen. I turned it on and seemed to tare okay but was not reading accurately. I pulled pretty hard on the hook and barely got to read two pounds. I restarted it and then the display showed a series of numbers and wouldn’t do anything else, I couldn’t even get it to turn off afterwards. Not very water proof... it seems as other reviewers have waterproof issues as well.

Ese B : It really waterproof!

Ordered this to replace my scale that fell in the water and quit working. And honestly I’m suprised with it! I put it in the water to see if it actually floats and it does! It’s a great product!

Chris McVey : What’s not to like?

I have 3 of these scales now. I have one in my Bass Bag, Cstfish Bag an Walleye Bag. I recently bought this one because of the Black Friday deal. I’ve tested it in comparison to other scales and I have found them all to be within an ounce of each other. So accuracy is not a concern at all. Not to mention it’s waterproof and it floats! And a HUGE bonus is that it comes with a fish gripper to attach to the scale to easily weigh fish.

Rob : Was good till it got wet

Was a good little scale. Like anything on a boat, it needs to be able to get wet. Putting a little gasket over the batter compartment doesn't do a whole lot of good if the clamshell (body) of the scale itself doesn't seal properly....

I gave it 2 stars only because it was a good little scale, sadly I ended up paying 10 a month to find out it isn't as waterproof as they advertise.

RT : Safe way to handle and weigh fish (for fish and angler)!

Charles jones : Not wasting my time with crap product

this thing is junk checked it’s Accuracy with a 10 pound weight it weighed 10.11 pounds so then I went and tried it with a 10 pound bag of unopened flower it weighed 9.2 pounds. Checked it against a friends scale and it weighed them accurately. I was a KastKing inner circle member but I am no longer going to buy or promote cast king anymore.

Driftin NC : Great price

Great product that’s easy to use and accurate the grips also do good

Anthony T. : Expensive For what you get

Decent scale...grippers are junk...

Amazon Customer : Was "weigh" off

Sketchy readings from time to time finally proven... Firstly, I love the water resistance and that it floats, has an easy to read display and is bright orange and easy to spot in my bag when I catch that first fish worth weighing. This was the second one I bought. Last year I bought one and it lasted the season...didn't work this spring so what the heck, I buy another. This one's been all over the place on perceived accuracy (like ~1.5# fish registering 12 oz) but was it just my eye? Well, the other day I caught an 18" largemouth that weighed in at ZERO pounds. I was able to get the scale to read >0 only by pulling it hard and yes, I tried several tares to no avail. So, freshly outside the return period I offer this review. It won't last long and may make you think you were like all those other fishermen that lie about the size of their fish. But maybe they aren't lying after all and just bought KastKing scales.

HollyAnne : Works in every way it should!

I bought this for my son and he loves it! Does everything he wants and not too large.

BW : Doesn’t last. 10 months now dead.

I wanted to like this scale...and for the first three months it worked fine. Then it began working intermittently. Now it’s dead. Purchased January, so 10 months of use. Not recommended.

J. Young : Awesome!

Started tournament fishing and needed a good scale option to cull fish during the tournament. I liked that this scale came with grips that you could hook on the lip of the fish instead of hanging it by the gills. Easy to use, backlit display, and not bulky so it fits neatly onboard my boat!

LC : THEY FLOAT!!????????

My wife bought me this and I use it any time I reel in a fish. Makes weighing and releasing much easier!
Thanks KastKing for such great products. AND THEY FLOAT!! ????????

M0onM4n : Accurate and simple

I received the scale and lip gripper recently and it appears the scale is very accurate. The lip gripper that comes with the scale is small, so may not be the best for someone with large hands, but it it closes tightly and feel confident it will do it's job. The fact that they are both orange / black is very nice so it will be easy to spot if laid down while I am out and being able to float is a plus.
