Review of the Suunto (D4i) Wireless Transmitter

As a friend, long time dive buddy of Sebastiaan and enthusiastic reader of My Scubadiving Stories, I am happy to act as guest-blogger here. Sebastiaan asked me to share some of my experiences with the Suunto wireless transmitter, which is available as an accessory with the D4i (and other Suunto dive computer models). I hope it gives you some insight in its advantages.

When I started diving I very quickly decided that I wanted my own kit but I couldn't part with a few thousand euro in a heartbeat, so after two years of slowly adding pieces of equipment to my set, I finally had everything I needed to go diving without making a pit-stop at the rental desk of Dolphins dive center in Brouwershaven (which has excellent coffee by the way, but that's an other story). Diving is all about safety, fun and reliable equipment. I owned a nice basic dive computer, however not as nice as the D4i and definitely not air integrated. After a bit of luck I had a few extra euro's coming my way and I decided to spend it on the D4i. I got the wireless transmitter as a Christmas Suunto special, so no charge. Awesome!

The review
So, how does it work? Well basically you find a free high pressure port on your first stage. Gently screw on the transmitter (or let the dive shop do it for you) and of you go! You will need to pair it with your D4i, but that works as every other heart rate monitor on a running watch. You leave the transmitter on your first stage, pressurized or not and thats it.

During diving you now have two air indications, manually and digital. I find myself checking the digital pressure 90% of the time. Manual is just for safety. The D4i calculates the air supply left in bar as well as minutes (when you stay on that depth) so that makes planning of depths during your dive easy. When hooking your D4i to the computer you can make a nice graph of your depth v.s. air use per minute and as I am addicted to stats (in diving as well as in running and cycling) I love this.

I only know basic computer stuff but the transmitter works intuitive and the data output is easy to understand. As it should be, because we don't want to worry about what a specific number means when we are 30 meters deep in some dark wreck in Zeeland or floating next to a turtle in the Caribbean Sea.

I can't always take my whole dive set on trips abroad, but I'll always take my Suunto D4i and transmitter. Hope you enjoyed my story.
