TASCO Essentials 4x30 Binocular

I took a risk in buying an inexpensive pair of binoculars. This model is cheap but also cheaply made. The eye focal is flimsy and can break because the plastic is flimsy. The clarity of the lens is reasonable for the cost. Again, I took a chance with this purchase because I wanted my young kids to have a pair of birding binoculars but they are not as durable like the Tasco Essentials 8x 21mm Roof Prism Compact Binocular

Ordered these low power binoculars for use in passenger reading signs from moving car. Eye cups not for use with glasses. View is quite clear for an inexpensive binocular. Great for kids.

This Tasco Essentials 4X30 Binocular is a wretched joke that does harm to Amazon and finishes off Bushnell/Tasco as a reputable vendor. Since my purchase Amazon has rewritten the product description, now describes it as an opera glass. Yes, it is a Galilean field glass, not a binocular in the accepted usage, and appears to be the same product as the even cheaper Bushnell branded version. More than that it is cheaply made, a dime store - arcade prize worth pocket change for a child. Whether or no Amazon posts this, or claims it is abusive, they should take the product back at their expense and apologize.

I'll get the good out of the way first...The carrying case is well-made and very durable. I use it for my other binoculars when I can. The lens cleaning cloth is the same size and quality of low-dollar optics. That's it. That's the good.The binos themselves are made of good materials, but feel flimsy. Optically, they're good. I can see clearly most of the time, but sometimes the focus goes way out of whack and can't be brought back. The center wheel only goes so far, and it actually pushes the eyepieces towards your face. I hate that. There is no diopter adjustment, so no fine-tuning. Also, the binoculars don't open wide enough to fit an adult's head (pupillary distance). The neck cord is a loosely-woven piece of round shoestring-style cord. It's falling apart and needs to be replaced. This pair of binoculars is $10. For $12, you can get these, which are worlds better...  Tasco Essentials 8x21 Binocular (Black) Don't get these. I'd say they're good for a kid because of the price, but honestly, for two more dollars you can get the 8X21 binoculars that I mentioned. The child will be so much happier. Bushnell and Tasco make some really nice optics for the money, but this isn't one of them. I'd give it 1.5 star if I could.

As far as I can judge, the magnifying power seems to be nearer to 2.5x than 4x. This means the product is of very little use.This is a pity, because the quality seems good, even if the low price is not considered. Being so small, there is only just enough room for my nose, but looking on the bright side, I think it would make a lovely toy, with appropriate supervision ( ie do not look at the sun)The product is significantly not as described on the box. If I can trust my memory, from the product description when I ordered, Amazon has removed a whole heap of data about this product - you don't have to be a genius to guess why.These are galilean field glasses, an expert would not call them binoculars, because there are no prisms inside. As far as I can tell, one lens surface is coated. A contact at Microglobe said the image field and magnification looked the same as a 4x Nikon binocular. I checked, and the Nikon has lenses of 10mm size - not that company's highest powered model then.Now the good points. It seems robust, absolutely no collimatiom problems, light, has a nice feel, looks good, is cheap, there's almost nothing to go wrong, it makes stars appear brighter, there is no image unsteadiness, comes with a nice fabric case, and even low magnification is of some use. You can see a little detail on The Moon.

El servicio de AMAZON impecable, en 48 h desde la compra el producto se me ha entregado en casa a través de agencia llegando en perfecto estado.CUERPO DEL INSTRUMENTO O MONTURA: de plástico duro y engomado, pequeño y ergonómico, pero se nota que carece de la calidad que presentan otros instrumentos más caros.ÓPTICA: correcta en los tratamientos ("fully coated") muy propia de la Marca. Las imágenes son nítidas, claras, transparentes y no se aprecia cromatismo, algo difícil con sólo 4X.Pero en la parte negativa hay los siguientes aspectos:a) Pupila de salida teórica de 7'5 (30:4 = 7'5) que no sirve para nada ya que el RELIEVE OCULAR es muy bajo y hay que pegar literalmente los ojos a los oculares.b) Un evidentísimo EFECTO TÚNEL, más acusado que el que suele ser característico en prismáticos de configuración 7X50.c) No es cierta la información que da el fabricante sobre unos pretendidos 217 m/1000 m, que serían 12'4º FOV o campo real. Sobre el mismo escenario y comparando dicho campo con el de otros dos prismáticos con un campo de 7º ( 122'5 m/ 1000 m) se puede comprobar que ese es el campo cierto de estos prismáticos.La bolsa es la típica hoy en día en todos estos instrumentos chinos de baja gama, así como el cordón de sujeción es también el mismo aunque, en este caso, gracias al bajo peso del instrumento apenas se nota.Considero necesario aclarar cierto concepto que he observado en mucha gente a la hora de hablar de prismáticos, telescopios y óptica en general: "¿hasta dónde alcanza?" Los instrumentos NO ALCANZAN, por ejemplo, estos mismos prismáticos permiten visualizar la galaxia M-31 en la Constelación de Andrómeda y que se estima se encuentra a dos millones cuatrocientos mil años luz de distancia. Considerando que un año luz son en cifra redonda 9.500.000.000.000 de km (9 billones 500 mil millones) ya se dirá lo que "ALCANZAN".Lo que hace un instrumento óptico es CAPTURAR luz, es decir, esto NO ES AUMENTAR, y si la capacidad de CAPTAR detalles de objetos que se encuentran a determinadas distancias y que queremos visualizar, si ALCANZASEN la visión sólo llegaría hasta cierta distancia y a partir de ahí sólo habría una especie de niebla o de pantalla de invisibilidad. Luego, los aumentos y, SOBRETODO, la calidad de las ópticas son lo que permiten que las imágenes sean mejores o peores y se vea con más o menos detalle. No obstante, la observación terrestre es más complicada ya que se realiza a través del fluido que es la atmósfera que con su refracción y su polución (ya natural, ya artificial), va velando las imágenes a medida que aumenta la distancia, pero eso sucede también a ojo desnudo. La mejor prueba la tenemos en el porqué durante la noche no se ve, salvo luces artificiales y también objetos estelares, Luna, que hay en el firmamento, etc.Estos prismáticos considero que se pueden emplear para la ópera o el teatro, pero no para otros usos, ni siquiera para un niño si lo que se quiere es fomentar en él una afición.

Binocolo piuttosto economico, ingrandisce 4 volte ma intorno all’immagine c’è sempre un fastidioso alone grigio. Consegna puntuale ed imballaggio perfetto.

Nice product..
