I have just recently become certified and I am starting to purchase my own gear. I am still trying out different BCs when we go diving to figure out exactly what we want. I already have my mask, snorkel, boots, fins and wetsuit. I am not in the market for a dive computer. I am thinking I would like a wrist computer so I can use in while we are on trips, renting equipment and when I have my own. I am looking for something that will work now while I am just starting out but will also be something I will continue to use. I am looking for something for under $600 so any advice you can give will help me out.
