It depends - new these are 8500$ MSRP, probably closer to 10,000$ by the time you have it set up the way you want it. This one isn't new, hence cheaper. It is, however a very clean setup combining the user friendliness of a Shearwater setup with the simplicity of a Hammerhead controller. I actually prefer this setup over the latest factory setups, since those need 2 extra small canisters for battery and electronics. My unit does not need either. I have also added a custom molded sheet of lead weight to the head, meaning the unit balances well and needs little or no additional weight. I had it exactly where I wanted it, but am quitting cave diving, so it is of no more use to me.
