Handle with Care 
2007-09-03
This monocular is the perfect size and magnification, but I broke mine the second time I took it out on my kayak. It handled getting splashed for a little while, but when it got slightly submerged it fogged up, (meaning water got inside). The fogging seemed confined to the eyepiece, and when I gently pried up the rubber around the eyepiece to find the source of the leak the entire eyepiece snapped off in my hand, and the lense dropped out! It looks like it was superglued on, and obviously that's where the water got in. I realize kayaks are a rough environment, and these weren't meant to be submerged, BUT anything advertised as water resistant should be able to handle a dunk or two in my opinion.
In summation, this will work great for you..... if you don't ever drop it or get it wet.
very nice scope 
2008-07-19
This 6 x 30 monocular is an excellent scope for watching wildlife. Good light gathering ability in a moderate size package. Easy to use and seems to take the knocks of hiking well. I can't comment on waterproof ability, as I do all my hiking in the high desert. Pros- nice field of view, well-made, easy to use with glasses and fits your hand nicely. Cons- a big heavy, neck cord needs some softer cloth around it when hiking, only 6x power and the little plastic cap does not fit tightly on the eyepiece when rolled back for use with glasses. Overall very good optic for the price.
good little scope 2008-06-13
I have carried this scope in my pack and car for a little over a year now,in environments from Alaskan rain forests to the Adarondacks.I have a tendency to be hard on my gear and this scope has been both rugged and reliable.Its performance has been excellent especially for the price.I would say its image is about 85% as good as a pair of $1000 binoculars I also own.Its low light performance has been surprising,we were able to glass ridges In the Chugach forest at 800 to 1000 Yrds for bear and goats at dusk without any problem at all.The Externa has proven to be an excellent buy
Good for the game fan or the neighborhood watch.

This is a handy little monocular. They are not nightvision monoculars. The 6x30 yields a good value for the exit pupil, five in this case, which is about what is needed to have any kind of performance at dusk. I've compared them to 8x10 models and these let more light into the eye at night making it easier to resolve the image. The smaller magnification means the image is less bouncy as well. Its good for watching games or carrying while on the neighborhood watch.
Excellent monocular 2008-01-09
The monocular has clear optics, is waterproof, and light to handle. An exellent choice for birders.
Reliable and compact 2007-10-25
I've had my Eterna for over two years now and it has handled everything from working on military ranges to treading through wetlands and climbing (backpacking) through Texas, Wyoming, Colorado, New Mexico, California, Mississippi, and Alabama. I haven't taken it rafting or anything like that, so could not attest to how it would hold up in that environment. I do know that it can handle pretty much anything a Marine or Geologist could throw at it since I've been both.
What I like best about this product is that it is compact and it doesn't fog up. I've used it to site in and safety ranges to deployment of wetland crossings and outcrop recon when gathering geologic data.
