On the Island Texel, we scan sheep on the amount of lambs they have, so we prevent a lot of caesarean and suffering with the triplets. Two students of the veterinairy faculty in Utrecht did prove that by collecting and analyzing the results.

I have used my 4 year old Ovi 6 this season after having the screen upgraded. I have also scanned a few thousand ewes with the new ovi 6 that we purchased for David.
I would say both machines are performing excellently now. The images are as clear if not clearer now than those I received with my old Ovi4. The major area for improvement I think is in sorting out very early pregnancies (28 to 35 days) and very late pregnancies (greater than 100 days).
On the training side of things the new screen gives you a bit more leeway with the angle of viewing the screen. The original Ovi6 machines restricted your optimum viewing area and you had to really emphasize the importance of screen positioning in relation to your eyes.
The software upgrades over the last couple of seasons have improved the background noise levels to where I like them and power and gain levels rarely need adjusting.
My one major change is that I now scan virtually all my sheep on 5Mhz. I don’t know if it is the balance between near and far gain for the different frequencies but I am more comfortable scanning on 5Mhz than 3.5. This is the opposite too what I did with the Ovi4.
David’s first season has gone well, a lot of good feedback on his results with very few lambs missed. I started him off with my old Ovi4, thinking the old reliable scanner would suit him well. In summary he hated it. Having trained on the Ovi6 he was not comfortable with the old images and really took to the job after we invested in the new Ovi6.

After testing out the pre-production model of the Ovi-Scan 6, I found the final model to be much better. We purchased and used it. It took a little getting used to, to get the settings as we like them. However it is a lot better to use in daylight and I found once I got it to my liking, the ability to hold your own settings is great.
This season, I purchased our second Ovi-Scan with the latest update – the LCD screen – which is brilliant. We sent our other machine back to upgrade to the new screen, well worth the money. The new screen has the image we have been after since the loss of the old analogue machines we started with. The image processing has improved leaps and bounds over the years, but the screens have let it down until now.
Over the 30+ years we have purchased many different scanners, over 30 in total and have lost count of the number of probes. We have always used 5meg probes for earlier scanning, and now the Ovi-Scan 6 picture has improved so much, my 3 daughters and myself are using 3.5 probes with great results. Great effort, thanks again. Will be interesting to see new machines over the next 10 years, keep developing them.
