----- Original Message ----- From: "Kieran Kelly"To: Surely Silva will have to introduce a similar model > or it will be out of business. As I said in my original post, global needles have been around for a while. Here are a couple of current examples in addition to Suunto http://www.silva.se/outdoor/products/comp_voy.htm http://www.venturesport.co.uk/venturesport_product.asp?parseid=738 Here is a fairly dated, but frank discussion on Brunton's effort http://www.kooters.com/sezbrntn.html As I said, my 45 yo Silva Ranger TD has worked fine around the world. 45 years ago the Ranger TD model was the very top of the Silva range, nowadays it is in the middle, tending towards the bottom of the range. Maybe the Suunto design is a breakthrough, I don't know. Certainly my impression is that other approaches to a global needle have relied upon a needle slung low below the pivot point, and riding on a superior bearing. Lee Martin
