This is a purely 1st impression type of review.

I decided i wanted a set of digital scales that will weigh a decent sized fish, as i have a France trip coming up and at the moment my Reuben Heaton Flyweights only go up to 40lb.
The biggest fish in the lake i am headed too is around 60lb.
So i was looking at a set of scales, that were not too expensive, compact and would weigh up to a reasonable amount.
I have just recieved a set of Korum Digital scales, they are a dark green rubberized coated scale comes complete with a PP3 9 volt battery and a neoprene case. They weigh up to 85lbs or 40KG.

They have a single on/ off push button, which is slightly recessed, so its hard to knock and accidently switch on, though if you do or it goes on in your bag, they switch off automatically after 30-45 seconds to save battery.

They have a switch on the side to go between lbs and ounces or Kilogrammes and grammes.
Having weighed an object in them, they read in lbs and oz, not decimals like some digital scales do.

To zero you just attatch a weigh sling before switching on the scale, then switch on, the scale is then zeroed to your sling, take off sling put in fish, hook up and weigh away. They then record weight which stays on the screen once it has settled for a good 30-45 seconds. The scales are very small and compact, take up no more space than my Flyweights, and all for £28.99 delivered

Or just use dial scales.Added bonuses are no batteries to let you down, can be left out in the rain and no worries that like other electronic things they stop working for no apparent reason.

Just do as Beyonce suggested, just weigh the sling on its own and subtract from total weight.
I would suggest altering your routine slightly, less handling.

1. (Eventually!) catch fish, unhook and leave in landing net while I get things ready.
2. wet sling
3. Break down landing net, put fish (in carefully rolled up landing net) into sling
4. Bring to unhooking mat, remove net from under fish
5. Take photo's and any treatments
6. Zip up sling, switch on scales and weigh, then straight back into the water.
7. Weigh sling on its own and subtract from total weight.

It may be that I am not adopting the most efficient unhooking/weighing routine. My normal routine is this:

1. (Eventually!) catch fish, unhook and leave in landing net while I get things ready.
2. (If it wasn’t for the time out issue) wet sling and tare scales
3. Break down landing net, put fish (in carefully rolled up landing net) into sling
4. Bring to unhooking mat, remove net from under fish
5. Zip up sling and weigh
6. Back to mat for photos, disinfectant, etc.
7. Zip up sling and back to water

By the time I get to 5, my scales have turned off.

Is there a more efficient way of going about things I wonder?

Strange, I have never had the scales time out on me by the time I get to weigh the fish which is probably why I have never had an issue. I can't comment on whether they switch off and will restart at the tared weight - I cant see that this would happen but I might check & see how long before they switch off anyway..

With digital scales I just weigh the fish, put it back, weigh the sling and subtract. Am I missing something?!

That’s interesting because I have those same scales but have ended up weighing fish+sling and then deducting sling, because they always timed out between me taring them with the sling and then being ready to weigh the fish.

Have I misunderstood how they work? Are you saying that even if they time out and automatically switch off, as long as I haven’t manually switched them off then they will start at the previously tared weight? I’d be mega happy if that’s the case!

I have been using the Reuben Heaton 9000 digital scales for a couple of years now, have never had a problem with the tare facility, seems to be enough time to sort the fish out after zeroing the scales etc. Apparently, the tare function doesn't reset until you turn off the scales, which explains why I have never had an issue - before weighing I always double check the reading on the scales to make sure they haven't reset. They never have so far. I still keep a pair of dial reubens in the car, just in case, but have never needed them. Good set of weighing scales and good battery life too. Highly recommended.

I’ve got the saber digitals, which are the same as the sonik ones. Yes, they also time out and switch off automatically too quickly for zeroing before weighing. I don’t bother anymore, I just knock off 1lb 14oz, which is what my Korda Compac weigh sling weighs wet every time I’ve checked it. So much easier.

Yes.

This is the case with my Avid scales and with my Korum scales.
I am now in the habit of reaching over to the scales and giving the hook a little tug to keep them 'alive' for another 30 seconds....or if my brother is helping with the fish care, he knows to keep the scales 'alive'

It is a pain. I like the auto-off but I think 2mins or maybe 5mins would have been better

I have a set of expensive original Fox digital scales but I never use them as the batteries used to go flat between sessions. I don't recall having the same issue with them

p.s. Fox and sister companies does not include Korum. Korum is the specimen arm of AVID (Preston Innovations being the match arm)

Does that mean once you zero them with the sling attached you have 30-45 seconds to get the fish in the sling and weighed.
If so I can see that time elapsing quicker than you think.
I can see the attraction of the physical size of digitals but I'm sticking with my dial scales

Quote... they switch off automatically after 30-45 seconds to save battery.....

And there is the reason i won't use any digital scales...that is simply not long enough...

The number of fish I have seen weighed on digital scales that have timed out and turned off automatically is ridiculous. They do not remember the tare so when turned on again the weight of the sling is included in the weight of the fish. An average retainer sling weighs about 31/2lbs so if you use digital many ought to take that off the weight of your pb.

If anyone knows of any digital scales that do not operate in this manner I would be very interested to know as I would like a set.

I thought I would jump on this as this spring I joined a new syndicate that has some beautiful carp in it but also some monster tench (rare in the N West) I decided to target them and get to know the water before targeting the carp.

Anyway, second session using method feeders and I get an absolute ripper of a take. I assumed it was a carp. I was wrong. It was a monster tench. Not only was it a monster. It was 100% a PB. On a closer inspection it was a male. I was blown away. This fish was easily a double. This fish was old. His fins were like frilly knickers and it was almost black. I was shaking with excitement.

I took my photos and got the korum digital scales out. Id only bought them a few weeks prior and they didn’t switch on. I was heartbroken. This fish would have instantly got me a drennan hat if the water didn’t have a media ban.

I should have known. I avoid fox and its sister brands because their gear is generally crap quality and korum are no exception.

Ill never forgive them.

At least I got the photo though.

Do you have tare the weigh sling every time you turn them on?

Hi all,
I'm having exactly the same issue with the scales – bought them as a back up to the Rubens & because they weigh up to 85lb, which is a bonus for fishing overseas... hardly ever used them, mine didn't even get wet or even remotely damp, think they went dodgy after simply putting the battery back in!

Where do they get returned to – the retailer or the manufacturer?

Cheers

I bought a set of these last year to use in my light stalking bag and for when i go fly fishing or lure fishing instead of having to lug my 60lb Reubens around.

Im disappointed with them to be honest.
They have hardly been used and have been kept in the supplied neoprene case, warm and dry.
The trouble is the LCD display has started to play up and is giving a faulty character display which i cannot trust as being accurate.
Which is very disappointing as i have not used them much at all.

So i couldn't recommend them to anyone due to my experience because i don't believe they have given me any acceptable value for money, as i can't use them or flog them on.

i had a set of these as my first scales and they were good to start with accurate etc but once a bit of moisture was about they packed up. I got a replacement and they packed up within 2 months. ended up getting a refund

They are just a different colour and re-brand to the other Chinese copies done by the likes of NGT and Stillwater.

Had to send my first set back as it came with a faulty LCD. How long the new set will last for, who knows.

I never fully trust mine as I am not 100% sure if they have zeroed or not.

Mine packed up immediately as well.

I have Wychwood T bars, been going strong for six years now with no issues.

The early one's had a plastic loop on the top which could break.... nearly dropped a 40+ with that.... There must have been issues as their now steel loops. Had a set for a few years now and never had a problem with them.

Temp gauge is a bonus! Battery has never been replaced.

Perhaps I just got a duff set.

I have a set of these, purchased about 12 months ago as I wanted a small travelling set for short stints and stalking. Initially, all was well, they are accurate (against my Reuben Heaton digis), easy to use and take up little space. Nice folding mechanism for the weighing hooks too.

All was well, until they got wet, which in their line of work is pretty unavoidable! Whether they are not a good seal or perhaps some other reason, the screen refused to work. I changed batteries (they take the same 9v rectangular batteries as Delkims) and they worked okay but would not switch off.

Have tried drying them out, but have the same problem. They won't switch off, and stealing the batteries off my Delks every time just to weigh a fish, before removing the battery again gets a little frustrating.

I could not recommend these scales. When they work, their great. When they don't my Delkims don't either.
