Hello y'all! I'm rookie in the sport but looking to buy my first audible altimeter. Safety first that is for sure. I have no real target in what will be my kind of jumps in the future but my mind is set to Formation skydiving and Wingsuit flying. Through the forum just found old information and very apart, so ask you skymasters to give an help. Just have around 50jumps I was waiting to buy the Dekunu alien thing but goog people offered me the L&B Viso 2+. I found myself marveled by the speed, altitude, time registry on the altimeter. Now I am searching for an audible altimeter with no consistent opinion yet. For this I would ask you opinion on such, so I can build my own based on your insight. I was fully mindset to buy from L&B but found 4 there! Optima II, Solo II, Quattro and Protrack II being something that is long lasting and I thought Protrack II would be great recording each jump data through USB to the PC. The remaining ones, I just believe Solo II to be outdated and could undestand quite well the difference from Optima II to Quattro... So I got stuck between Protrack II and one of those two remaining. After some search, I found also AON2 Brilliant Pebbles. Without the LCD display nor any fancy show around stuff, it is so much cheaper! However I am not sure it get any jump information in its memory, when comparing with the L&B altis. Another important input is that I am in Portugal (EU), importing stuff from Australia or US has many times significant costs. So, in the end. For sure I wish a accurate audible altimeter for safety purposes. But the I would like to keep info on the jumps, it would be great to download it. If you could share your experience and knowledge, I would be so much thankful! Blue skies! Diogo
