Hello
I use a Pulsar N550 Digisight, and twinned with a Laserluchs Laser IR, or indeed Pulsar's relatively inexpensive new L-808 Laser, it is a formidable device. Even in low ambient light with the L-808 i can comfortably use it for spotting small ground game out to 150meters.
I have vast experience in night vision use, and can honestly say the N550 would be my first choice when it comes to budget night vision.
Using the word "budget" for a 1000 piece of NV kit might be frowned upon but having used many Gen 2+ devices over the years, you really do need to spend almost double that to get comparable performance, certainally for rimfire and centrefire ranges out to 200meters.
I have used a few 3k pieces of junk that really beg the question that you should always try something before you buy it.
Should you be interested, Scott Country offer a "try at home" demo Digisight, where you can borrow it for 7 days and try it in the field.
There is lots of heresay in Night Vision and I urge you to try kit before you make your decision as the Digisight does take a lot of beating and it, like any product, has fans and foes, but people who have used them properly will tell you how they take a lot of beating for the cash.
Mike Powell from Sporting Rifle uses lots of night vision kit for example, and his own device is an N550 Digisight.....
Thanks for reading
