For on the water feedback, both spoken audio speeds and instant results in all categories on the screen, it is hard to beat a cheap Android smartphone running the GPS-Logit app:
The phone GPS results are not consistent enough, and don't include vital error data for verification so it is not suitable for GPS-TC posting, but it is perfect for just keeping track of your session as you go.
Here is the description, but you need to download it from the Google Play store.
Last I looked, the Alcatel Pixie 3 (4") was still available from Officeworks stores for $19!
www.officeworks.com.au/shop/officeworks/p/optus-alcatel-one-touch-pixi-3-prepaid-mobile-phone-op3000641gps-speed.com/gpslogit.htmlThere are a couple of excellent cases around for GPS devices, but
for phones, especially to use with earphones, the H2OAudio armband case is in a league of it's own. It is really tough and durable, has clear plastic for viewing the screen and has an earphone plug and socket. The armband is very good and easy to adjust and the back of the case has a grippy pad to keep it in position. On top of that, the Alcatel pixie 3 (4") fits perfectly, as do a number of other low cost 4 inch screen Android smartphones. (I would not use an expensive phone in anything near water, no matter how good you think the case is!)





I have a few of these cases available. PM me if you want one.
