Bought this rangefinder from JSR. Usual no nonsense overnight delivery and fair price. It is an Opti-Logic 400XL. Go look at http://www.opti-logic.com/xl_series.htm for more info. Interestingly they also do a 100 yd one for archers.

For me I shoot .22 and wanted to have something that might help me get accurate ranges particularly in the 30-50 yd bracket where 1 yd can mean a lot of POI shift. I tend to use it when sniping and basically it allows me to creep into a position with minimum disturbance then range find a number of fixed objects in my potential 'killing field'. Once this is done I wait till rabbits wander into range and and then holdover according to where they are wrt my known objects. Practically I tend to just establish my 30yd boundary then don't shoot anything unless it is inside. I could also have done this with the laser mounted on my scope zeroed to 30m I suppose.

Things I like about the range finder are;

Price £129.95 new from JSR.

Ranging Accuracy, checked it out on my marked range and it is just as it says on the tin which is +/- 1yd when used on a distinct target. (From the mfr website the newer ones look to be +/- 0.5yds.

'Brush cutting' - using a bit of common sense when ranging on targets it is pretty good at picking out things between trees/branches so has a suitably narrow beam for my needs.

Silent mode - you can turn the noise off !

Red dot targeting - you look through the eyepiece and put the red dot on the target image. I am able to range off swallows sitting on the telephone wire at 22yds outside the house agaianst a clear sky. It wont pick up the wire. (NB you are not physically putting a red dot on the target as you would be with the laser on your rifle, it just appears in the image)


things that I am less keen on are;

Didn't come with a lanyard
Carrying pouch is black not camo.
Not waterproof
Doesn't magnify the image though this does mean you have a wider field of view which I am happy with but you can't substitute it for your binoculars.

Minor word of caution, make sure you have a good battery in it as the readings go to custard if the voltage is down.

How are they at rangefinding at 100yrds +, is it difficult to hold it steady on a rabbit at this range?

I was rangefinding on a rabbit at 75 yds the other night with no problem but I wouldn't be looking to shoot out to that range. Practically beyond that you would be starting to struggle because a rabbit at 100yds without magnification is probably going to be smaller than the red dot you see in the viewfinder so it is getting difficult to discriminate the target. However you can just range off the nearest bigger thing to the target. I routinely range on tree trunks/thicker branches out to 400yds.
