Re: Oehler Chronographs
I have been using a CED Millenium chronograph for about 5 years, after 30 years of using Oehler, from model 10 up to 33.
I did not notice any difference in velocities recorded by the CED with my field loads, that I had previously chronographed on numerous occasions with the Oehler.
I am using the standard CED 2 foot spacing, but according to the CED manual, they are also available with 4,6,and 8 foot bars. However, I believe the 6, and 8 foot bars will require the use of 2 tripods whereas the 2 and 4 foot one can be mounted on a single tripod.
However, having used a 10 foot spacing on the Oehlers for 30 years, I am not yet completely sold on the 2 foot spacing idea, and am considering moving to a longer bar at some stage.
About 1 year ago, one of the sensors stopped working, and although it was under warranty, I just bought another one (US$23.95) as it was the quickest way and suited my circumstances at the time. The replacement has worked faultlessly since as you would expect.
I have gained the impression that the CED does appear to be slightly more sensitive to low sun angle late in the day than my last Oelher, but it is difficult to be definitive about it.
The CED is quick and easy to set up and appears a sound system, but am not implying that it is the best. Brian.
