Questions about KastKing Water Resistant Digital Fishing Scale with Ruler, Dual Mode – Pounds/Ounces & Kilograms, Zero-110 LBs/50 Kg, Light, Strong ABS Frame, Non-Slip Handle, Retractable 38 inch Tape Measure

My scale is showing “unst” on the display and is not functioning correctly? Is there a fix for this?

Will this scale show highest weight measured such as when you are setting your reel's drag?

Answer: You can use this to set the drag, there is also a memory feature to save weights.

My manual is in chinese or japanese.. could i get an english version. thank you

Answer: Contact KastKing, they have great customer service.

Is this scale certified and calibrated?

Answer:

Answer: Hell yeah! Also has a neat lil clip for the hook and a measuring ruler

I have the older scale. no tape measure and round batteries. i loved it until i cant find batteries. is this one better? and how is it better?

Answer: Hi there,

Does it have a fish lip clamp option vs the hook? Or can it be purchased as an option?

Answer: Hi Bruce,

Answer: I just hook it onto the keyring on my fish gripper. Works great.

Is the handle big enough to hold with 4 fingers ?

Answer: I can hold it with 4 fingers. The opening is 2 3/4 inches wide.

Answer: Yes, I can hold it with four fingers.

Answer: Yes, unless you have giant hands. I wear an XL glove and mine fit fine.

Answer: Yes it is.

Answer: Yes of course it is

Is this scale really waterproof?

Answer: First of all, they say it's water RESISTANT, so I'm pretty sure it is not waterproof. I do know there is a thin gasket (silicone?) around the battery compartment cover. I assume there is a gasket between the two halves of the case, but I'm not going to open it up to check. I'm almost positive the measuring tape compartment is not waterproof, because the slot the tape comes out of appears to be just like any tiny measuring tape slot. My thought: if saltwater gets in there, it's curtains for that measuring tape.

Answer: I can’t say if it’s WATERPROOF but I think water resistant is a better term. Mine has gotten splashed and rained on several times with no problems but I wouldn’t bet on fully submerging it for any extended time. Hopefully that helps!

Does this scale have a tare button to use with fish grippers or net? I dont see an option for it.

Answer: Hi Luke,

Answer: Yes, you can use the middle button (POWER) briefly to tare.

Does it round to the nearest thenth? So would 2.36 round to 2.4 or will it show the minimum at 2.3?

Answer: I do not know if it rounds up or down. I'd guess if you need precision like that, a hand-held scale won't suit your needs.

My scale says err when turned on. how do i get it to work now?

Need better operating instructions don't discuss the duel mode, more detailed instructions any where?my purpose weighing feed per horse need to + or -

Does this scale have a weight hold function?

Answer: Not sure what you mean by weight hold function but it does allow up to 10 seconds for the load to stabilize and beeps when the weight reading is locked in, the weight reading auto unlocks after 30 seconds or can be manually cleared by pressing the power button once. It also has a Save A Weight To Memory and allows you to save up to 10 weights. hope this helps.

Answer: Hi there,

Answer: Yes it does jus have to hold down the left button and locks in

Answer: Yes. Three saved slots.

I want a meter to read thrust. Can this be set to read peaks, or does the data hold just look for stable readings and then it stops?

Does this come with a lip gripper included

Answer: It has a hook but don’t think I call it a lip gripper.

Answer: No but I think they do have a scale that comes with one of you want both.

Answer: No. It’s got a hook for weighing fish

Answer: Solid scale and seems to be accurate.

Answer: No, you have to buy one separately. I used one from an old scale I had.

Answer: no

Answer: No

Answer: It does not.

Answer: No

Can it zero out? I want to use my fish grabbers to hold the fish rather than the hook.

Answer: Yes it will.

Just received the scale and it looks good. Is it supposed to have an audible beep when it locks in the weight? Mine has a blinking red light.

Answer: No beep that I know of.

What is the process to zero it so a fish grabber can be used to hold the fish?

Answer: Just put the fish grabber on, then press the power button. It then zeros out. Then attach fish to get accurate reading. It’s a great scale

Answer: Sorry but I don't know. I will try to find out, for you AND for me!

Does anyone know if this floats?

Answer: Hi Llong,

Answer: I haven't tried it, but I seriously doubt it. You might want to consider something like those floats for your car keys or a retracting tether for the scale.

Does it come with battery’s

Answer: Hi Forest,

Does the scale have a peak function? I need one to weigh my bow draw weight.

Could this double as a compound bow draw weight scale?

Answer: I believe it would work. May need someone else to read it for you while you’re drawing the bow though.

Answer: It could I guess but you might want to modify the hook or squeeze it closed some

Will the Rapala 6" gripper work with the hook on this scale? I have a scale that the hook will not slide through the provided hole.

can it weigh small items, like a few ounces?

Answer: It has several different weighing options. It has a lb/oz option in which I've weighed something as light as 2 ounces. (The lip grippers)

Answer: It will weigh as small as 1 ounce.

Unfortunately mine didn't come with any instructions. and, i can't find them online. can someone point to where i can find these online? thanks!

Product reviews of KastKing Water Resistant Digital Fishing Scale with Ruler, Dual Mode – Pounds/Ounces & Kilograms, Zero-110 LBs/50 Kg, Light, Strong ABS Frame, Non-Slip Handle, Retractable 38 inch Tape Measure

Brenden : Genius Design!

This scale is genius! I love the built in measuring tape! Kastking has very nice tools and this is the icing on the cake!

Cole : Not very accurate

Checked it to my neighbors certified scaled and it was almost 2 lbs off when I weighed a 15lb piece of steel against his.

Carroll B : Worked for two years then would not turn on

This worked great for about two years, then would not turn on. I replaced batteries and it worked again until tit turned off then would not turn on. I suspected batteries but they measured 1.5 volts each. I suspected battery contacts but that did not solved the problem. The only way to get it to turn on now is to remove the batteries and put them back in. It has never been abused or wet. I will trash this one and buy a different brand.

nathan : Very good addition

I finally had to replace my old scale and am very pleased with this one. Nice grip easy to use and read and the included tape measure is a nice touch. Take up less space in my tackle than my old one too.

RD : Feature packed scale!

Bright backlit display, tough rubberized handle, integrated measuring tape, this thing has it all. Multiple units of weight and the ability to zero the scale after attaching fish grips is an awesome feature! It even has a memory bank to save previous weights. If you're looking for a quality, feature packed scale at a great price this is it. Well done KastKing!

Mike3756 : Top quality products!

I love the new scale always nice to have a way to measure and weight your catch. KASTKING products have been great for me. I have reels and line. All great quality and will continue to purchase kastking products!

Hayden Cook : Awesome product, great price and functionality

Love getting to use this out on the lake. It is sweet actually being able to get specific weights of our prized catches and it is neat how you can store multiple catch weights in there for comparison. The tape measure is handy too for figuring out the weight and length quickly.

susana dellariva : Junk.. buyer beware

Zero quality.... First time I used it all the paint flaked off the integrated tape measure when trying to measure a fish for the regulations in my area. Weight memory function doesn't work. You get what you pay for.

Beezy : Kastking Fishing

Kastking fishing, this is one of the best scales i have seen or used to this point. Big thumbs up. Oh and if you're a fisherman or fisherwoman you should get you one.

Hootie : Nice compact scale

Nice compact scale. I like that it has a spot on the back to clip the hook in when not in use, really nice for storage. The built in measuring tape is a nice addition. Can quickly weigh and measure the fish and get it back into the water quickly. The screen lights up so you can even use it while night fishing. Also having triple a batteries is a big plus over the little watch batteries that some scales use. Every KastKing product I have bought has been excellent.

Ewalds : Works like a charm

I tested it against some weights I have at home and it was accurate. It was inexpensive and does exactly what I hoped. I use it all the time.

Amazon Customer : Awesome Fish Scale and Tape Measure Combo!!

The scale is accurate, easy to use and the back lit display is clear and easy to read in the dark. My favorite feature is the tape measure runs parallel to the scale hook so you can measure the fish at the same time you are weighing it. Water tight battery compartment and rugged build make this an easy choice for beginner or experienced fishermen. Thank you KastKing!

Karen Hughes : Hubby loves it

They were always losing the ruler. This includes the ruler and can be hooked to something so it doesn't get lost from the boat! LOVE IT!!!!

Christopher Swain : Good product for Fishing Use

The scale seems very accurate except it doesn't show 2 decimal point accuracy but for use as a fishing scale it's accurate enough.

Stretch : Accuracy

Locks weight in too fast for me
. 10 seconds.

Kevin O : Not bad for the price

I think it’s a decent scale. It’s probably a little more accurate compared to other scales that are in this price range. It’s a little bulky but it gets the job done.

I really don’t think you should use the hook on it as a gill hook. I pair mine with a fish lip gripper or so I don’t hurt the fish. The hook is too small and you’re likely going to damage the fishes gills while trying to hook them with it.

Josh : Not worth the money. Stay with name brand fishing gear.

Bought this in May and it's now September and its stopped working. Its been used maybe 5-6 times and kept in a dry storage box in my bass boat. Ive changed batteries and it just shows "UnSe" across the screen.

Andrea : Great product. Great value

This scale is everything I hoped it would be! It’s sturdy, and high quality. Great value for the price! Love the fact that it came with batteries.

Christopher Swain : Good product for Fishing Use

The scale seems very accurate except it doesn't show 2 decimal point accuracy but for use as a fishing scale it's accurate enough.

Eduardo : Had to buy it!

I've had good experience with Kastking and own many of their products. So when I seen this scale I went ahead and purchased it! Definitely an upgrade to my prior scale. Really sturdy and easy to read and use. Hopefully Kastking keeps up with their competitive prices and quality and will stay a loyal customer.

Brad M. Hendrickson : Nice features

I like the features. Won’t accidently turn on. Turns off automatically. Has memory to keep it set at lbs. also reads ounces.

Richard Boureston : Works great.

Seems like a good scale. Tested it with several known weights and it was within an ounce. I did a basic water test and it is still working.

Hayden Cook : Awesome product, great price and functionality

Kevin : Awesome products

Love love love KastKing products. Cheaper than the brand names and work even better. The tape measure comes in handy when weighing.

REG : Great scale

Love this scale. Easy to use and back light is amazing to help see display. The hook snaps onto the back so that it does not get tangled when trying to retrieve from box. handle is non slip and wide enough to get my fingers into with my kastking gloves on. Stores up to 10 weights and you can pick which slot you want to replace with a new weight. Would recommend to anyone looking for a great scale at a fair price.

Adventurist : Get the waterproof one

The scale works as advertised but what good is a scale that can't be accidentally dropped in the water. They make a waterproof version for like 3 dollars more, get that.

Carp : Works as advertised!

Dropped this bad boy right in the water on the 1st use lol. Still working and measuring accurately. Last King products are quickly becoming my go to brand for all of my fishing needs.

Laura Martinez : Not water proof on edges of screen power button broke after one use

Carried it with me into river to weigh and measure fish my first trip using it. Stored in my bag I pulled it out had water that seeped through screen then it would not turn on. I replaced the batteries it turned on but not off. left for a few minutes the screen would shut off. Pressing the power button it would not turn on so weighing my fish was not an option. I will not carry a screw driver to keep trying to turn on the scale during a trip.

Mr.Y : Not quite accurate but will do the job.

Item came as described, but it was not accurate. I compared it to 2 other scales while fishing and this one seemed to be off on accuracy. It kind of works since it’s better than nothing but it would have been awesome if it was accurate.

Beezy : Kastking Fishing

Kastking fishing, this is one of the best scales i have seen or used to this point. Big thumbs up. Oh and if you're a fisherman or fisherwoman you should get you one.

Kipp : Cool design

So far so good. Like that bilt in tape measure.

Jason anton : Not high quality

Scale portion works so so. Sometimes you have to hit the button a few times before it works. The tape measure is hot garbage. The yellow came off after first use, rusted after the second use, and broke by the third.

Chris McVey : Easy to use, incredibly accurate and has a ruler built in!

Very easy to use. Alot of scales do not toggle well between KG and Lbs. This one does very easily. Also, the scale has the non-slip grip that make it easy to hold your fish. Works very well with no puncture fish grips. Also the scale is incredibly accurate to the ounce. I weighed a mailing package with USPS with a preshippimg label and it was the exact weight at the post office. Definitely nice knowing if your tournament fishing. This scale has a ruler built in as well! Great value for the money!

Jonathan Chestnutt : Not perfect, but I’m happy with it.

There is a small imperfection in the display. It is under/in the glass and cannot be cleaned off. The manual said it would make an audible beep when the weight is locked in, mine makes no beep but that’s not a big deal. For the most part it seems to be well built and function properly.

customer : fish scale

works good

Cole : Not very accurate

Checked it to my neighbors certified scaled and it was almost 2 lbs off when I weighed a 15lb piece of steel against his.

Mike3756 : Top quality products!

Rod : The black rubber on the handle started to melt off...

The black rubber on the handle started to melt off before i could weigh fish #2. It must be too hot in Florida for whatever the black handle is made of. I keep it inside the house when I am not using and still this happened. The device itself seems to work like it is supposed to. Just wish it would have stayed nicer newer longer. Any help from customer service here? pics to come

J Maize : Easy to use and read

So far so good. Haven’t got to use the scale in the field yet but I will get to use it this Memorial weekend. The handle is comfortable to hold but the body is made of plastic. Not sure if it will actually hold up to 110lbs but I hoping to find out. I did test it out on some known weights and it is very accurate. I will update this review if anything changes.

Tressica : Best scale for the money

Awesome scale, easy to use. Love the memory feature and the fact it has the retractable tape measure. Perfect to make sure fish is legal. Best scale in this price range by far

J Maize : Easy to use and read

Kevin L. Davis : Great product and quality

I love this thing. I have weighed a ton of fish just after a couple weeks of fishing. Great product and good quality.

Russ : Great scale for the price!

Have not had a chance to use this on a fish yet, but it really seems well built. Super simple to use the scale, and the back
Iight makes it very easy t read. If I have one concern, it is the tape measure part. The tape feels kind of cheap, and already does not retract all the way if let back in slowly. Ultimately, I bought this one for my sons new KastKing tackle backpack, and I will likely buy another for myself.

Kevin L. Davis : Great product and quality

I love this thing. I have weighed a ton of fish just after a couple weeks of fishing. Great product and good quality.

RRak : Grandson approved.

My 14 year old grandson loves w. He was looking for something portable and lightweight. This went above expectations. Highly recommend.

susana dellariva : Junk.. buyer beware

nathan : Very good addition

jspicer : Love kastking products

Really like this scale! Easy to read has memory storage for 10 weights! Very accurate.

Kipp : Cool design

So far so good. Like that bilt in tape measure.

Hootie : Nice compact scale
