Bloody brilliant, as good as the more expensive ones my mates use. One problem I have is trying to zero it in daylight. More than likely me being not very clever with technology.

You will not find a better quality thermal optic with these features for THIS price anywhere, EVER PERIOD! p.s. they have outstanding customer service and support on top of an amazing product. (I paid for my scope BTW it wasn't given to me for a review)

Overall I'm very pleased with my scope and monocular. My only real gripe is on the instructions of sighting in. It doesn't explain how to get to the settings of up and down, left and right adjusting, I pretty much had to play with the knows until I got there. Then it didn't say adjust to the bullet hole, or adjust towards bullseye. I finally got it, after about 8 shots. Other than that I'm happy with it so far, and it seems to be of good quality for the money, I'm happy with the purchase currently.

The scope for the price is amazing. It is well made, user friendly. This is my first thermal scope so for me it was a new experience. The battery time is brilliant, the ease of use is great. The choice of thermal themes is brilliant, and the availability of adding a second battery is perfect. It shows the battery level for both batteries. The buttons on top are a perfect size for fingers with gloves. However, on the downside. The zoom is very poor above x2 as it becomes very pixilated. And I can’t seem to figure out the range finder. The battery cover is extremely difficult to put back on without cross threading. The manual could do with being a little more in depth on a few items and explain how they work rather than just what the icon is. I had only seen reviews online and felt a set up video from the makers would have benefited those who are new to thermal scopes. Sort those few little issues and for me it would then get a five star review.

Easy to learn, easy to use, works well for me on the farm to Identify vermin that need to be eradicated so the chickens and ducks can live in peace.

Hi not really had chance to use it properly yet got it zeroed at short distance for sub 12 air gunning witch was easy to navigate on the controls.The build quality is good and a good selection of articles and palette colours to suit your needs.

Fantastic piece of kit. The only negative is I am unable to turn the diapoter adjustment and have not received an answer to e-mails to GOYOJU as to cause. Nothing in the manual and probably my own stupidity.

Fantastic price, and so far I’m very pleased and impressed with the quality of the scope.

A very nice littleunit and being featured heavily on my youtube chanel. Although the optic is very good for a budget end scope i feel the audio side of things need improving . Ibe done a lot of shooting with this scope and it seems to work very well and for a 25mm optic its clarity is very good. Ill be further reviewing this scope on my youtube platform as there seems to be a lot of intrest growing around it . The reason for the 4 stars is soley down to the audio quality for me being a creator, but this doesnt take anything away from the great performance of the optic and Balistic calculator functions .

For a budget thermal scope it's really impressive. I wonder how much better a high end thermal scope would be side by side.

Хочу вибачитися за попередній відгук — зробив його поспіхом.
Після детальнішого використання прицілу GOYOJO GRS225RF з LRF можу сказати, що акумулятор тримає стабільно 5–7 годин, що є хорошим показником.
Прилад працює коректно, свої функції виконує, загалом якістю залишився задоволений.
Враховуючи позитивний досвід, замовив ще 2 таких приціли.

В мене був повністю заряжений акумулятор 18650 на ньому він пропрацював 1- 1.5 години. Поповоду далекоміра булоби не плохо щоб в нього теж мінялася цвітова палітра так як на прицілі. Його булоби краще видно

Користувався прицілом GOYOJO GRS225RF з далекоміром. На жаль, прилад не виправдав очікувань.
Основний мінус — акумулятор тримає дуже мало, приблизно 1–1,5 години, що критично для полювання.
Також вбудований далекомір працює некоректно — часто показує неточні або нестабільні значення.
Через ці недоліки прицілом залишився незадоволений

Дякуємо за ваш відгук.

Хотіли б уточнити, що GRS225RF має час роботи від акумулятора до 7 годин при використанні повністю зарядженого акумулятора 18650.

Акумулятор CR123 – це одноразовий акумулятор з часом роботи від акумулятора 1-2 години.

На продуктивність далекоміра можуть впливати умови навколишнього середовища та тип цілі. Усі пристрої тестуються перед відправкою.

Будь ласка, зверніться до нашої служби підтримки для отримання допомоги з тестуванням та налаштуванням.
