Pilots in search of a lightweight, durable, quick-donning view-limiting device for simulated instrument practice will love ASA's Overcasters. Unlike traditional foggles, these clip-on visors easily attach to eyeglasses and are designed with quick flip-up capability to simulate "breaking out" on an IFR approach. Their compact size allows them to easily attach to a variety of items for secure, close-at-hand storage, and their dark color and shape ensure your eyes stay focused on the gauges. Affordable, lightweight, compact, and sturdy, Overcasters are an ideal training tool for every IFR pilot.
these look as advertised, have not tried yet but I expect they'll work as advertised.
Nice, yet low quality
Purchased a pair of overcasters as I cannot fly without readers. The device is simple and achieves the desired blockage for IFR simulated flight. Provides a very easy transition between IFR/VFR which is what I was looking to obtain. The downside is the quality of the material - a very thin plastic. Mine were bent out of shape when received and required a bit of heat and weight to mold back into position. No case for protection in your flight bag, so they require a bit of TLC to keep them in good shape. Applicable for the price, yet would of paid more for a more sturdier product.
Great foggle alternative
Really had a problem fitting my foggles over my reading glasses. These served the purpose really well. Clips on with no problem to my glasses, and can be flipped up when I need to go visual. The clip can sometimes come off the glasses, but you get used to it eventually on how much pressure to use when flipping it.
Overcaster for IFR practice
I had a set and they were stolen long with my flight bag. These work great if you have to wear glasses to see and want to do some hood work.
