Personally I'd rent or borrow for a year or two in an effort to see what works best for you. After 2 years I ended up buying a used Shearwater Petrel 2. Love it. Easy to change AA batteries. Simple to set up and download the latest and greatest software. Great viz under the water. This gadget is a jewel. I would never have paid for a new one but sure glad I waited and bought used. So far anyways. Lots of good DCs on the market. Patience is a virtue as they say.
