A few days ago I was surfing the web and I saw that there was no site displaying information about diving prescription masks, so I decided to write an article, helping those who might need it.
A diving prescriprion mask is almost a normal diving mask, only that it is for those who have eye problems. If you usually wear glasses and you want to practice diving, you surely need one of these. There are many types of lenses that can be ordered for anyone's prescription, so that you have no problem under water.
A few sites selling diving prescription masks: Prescription Dive Masks, Rx Dive Masks, Sea Vision USA.

Here we have what I call a great invention: the talking calculator. This is a multifunctional device, mainly used as a calculator. The best thing about it is that it speaks loud what you are typing, so that you type correctly. It supports two languages: English and Mandarin.
The talking calculator also has many other functions, such as alarm, time displaying, calendar, etc. Another great thing is that it can be powered by USB or by AAA batteries.
This useful gadget is available HERE, for only $23.
