Potential customer on the prowl. . . . .

+1 Me as well.

I smashed my ON/OFF button, but they replaced it free of charge. Had them send a replacement to a guy up north (further north) as he is shooting my 338LM/powder combo and I wanted to see what it did at lower temperatures. I'll get mine back in April.

I have descovered that as soon as the battery life gets down to 3 bars it dosnt like turning on.Sent my first one back and got a replacement one thinking it was a fault but the replacement one does the same and have been waiting for a reply from them regaurding their thoughts on this as I would have thought it would work right down to the last bar.
To be honest I'm not overly impressed and proberly wont use mine again now I have got a replacement sensor for my CED M2.

ive found that even tho it says to use alkaline batteries which i havent yet
the old standard batteries dont last very well suppose i should get some alkaline ones i guess

Alkaline is standard isn't it?

not when we ve still got the old ever red s

Just tested mine today for the first time. Shot over it with a 270Win pushing 140 VLD's, and a 7mmRM pushing 180 VLD's. Both loads I have used for a long time. The upshot is this thing is quite good. No velocity variation with light changes at all. Results when compared to 26 x 3 shot strings through the 7mmRM recorded in my range log book shot over a Prochrono came in at 10 fps under the average for all those strings. However the variation of those 26 x 3 shot stings measured with the Prochrono was 72 fps depending on the ambient light at the time of recording. My range book only lists the light as "sunny" or "dull" aganst each string (not very scientific I know).
I set up the Superchrono at a measured five yards from the muzzle as I normally do with the Prochrono. 18" under the line of sight, aimed at a mark 18" under the centre of my target. The target was 100 yards away. Everything I have read about the Superchrono emphasises the need to be parrallel to the bullet path. I also used Alkali AA's as suggested by the manufacturer.
I will carry out a more comprehensive comparison when I get time (in a month), but initial impressions are good.
It does however take a little longer to set up properly than my Prochrono, but the results are less shots for the same information.

Well mine arrives on Friday, so had a play this weekend at the range.

My Shooters Chrony often gives E1 errors so I was keen to see how the acoustic one compares. Shooting a 223, the Super Chrony reads about 50fps lower than the Shooters Chrony, any the last 3 shots at the RH target gave E1 errors with my Shooters Chony , but read ok with the new Super Chrony.

I've had a suspicion my Shooters Chrony is reading high for a while now, so I think the Super Chony's 50fps lower readings are probably more accurate.

The super chrony is much quicker to setup, less sensitive to poor light conditons affecting getting a reading, but for gods sake why did they go to all that trouble making a custom moulding and then not make the display vertical so you can read it from the shooting position! .... I now have to get up and walk in front of the firing line to read each shot, and find something hard to write against to record my results. Stupid design faults like that make me wonder what the designer was thinking of...they have ruined what could have been the ultimate chonograph!

NB I had it set up just in front on my Shooter Chrony, so about 2-3m out from the muzzle. I suppose I could bring it in closer, but I'm really struggling to understand why they would make the LCD screen at such a flat angle! I must admit that was my first thought when I first read Norways reviews, but nobody else has pointed out the difficulty in reading the bloody thing from the shooting position.

Cheers

A good point raised there. I had noticed the same thing before I got mine, but it didn't stop me buying one. I haven't really found it to be a problem as I use it at my own range, so it's not like I have to wait for others to stop shooting to retrieve the data. I have heard there is a new model coming out that has bluetooth. So you can view the results on your smart phone. No idea when it's due to be released though.
It's still a huge improvement on my Prochrony in that it will record 99 shots intead of one which I have to write down after each shot. I hope to get out in the next few days and try it under the target at 300 yards. I guess it won't matter about the display angle then
