A practical multipurpose whistle
Used for More than 1 year
I have been carrying the whistle on my treks. The one time I did use it was to let others know where I am when we got separated on the trek. The whistle is loud enough to be heard by someone who is far away on a normal day but I dont know how audible it is when there is a lot of background noise during a storm or heavy rains. The compass functions very well. The thermometer is good only for seeing the general ambient temperature. It doesn't give the exact temp readings. its a few degrees off. One suggestion is if the compass can be made to glow in the dark, it would be really helpful while using it in the night. Overall a really good product to be carried along always
built quality is not satisfactory
Used for 2 to 8 weeks
Had bought this for my chadar trek but the plastic facing the thermometer side cracked even after keeping it inside a pouch with other medicines and camera batteries. Not sure what caused it to crack.

Response of the brand
Hi Grant,

I'm sorry you did not receive the orange whistle.  This model comes in 4 colours but all linked to the same product code and this is not mentioned on the website or reflected in the product images.

I have asked our customer loyalty team to see if they can get our warehouse to pick and send you an orange compass and I will speak to the retail supplier to see if we can update the codes to have one per colour or at the very least to update the images and website to show that the compass can come in one of four colours.

Again my sincere apologies and thank you for bringing this to my attention.

Took it on our Scout expedition to Estonia.
I didn't need to use the whistle but because we tried it before we left , we know it does sound well.
The compass was used a little and found the themoneter particularly useful! We did use this a lot throughout our expedition.
The themoneter was great.
