So for $4.50 difference you're going to take a chance?

Remember, a smaller boat also means you have fewer options for placing the thing away from other devices that might interfere with it.

The range that they quote is the absolute maximum best-case, with straight line-of-sight and no electrical interference. I wanted to put the adapter down below in the cabin, a few inches behind the radio (so I wouldn't have to splice a wire onto the radio's pigtail). The potential for electrical noise in that location, and the industrial adapter's greater resistance to noise and adjustable antenna, made this a no-brainer for me. At the time I purchased it, the industrial version also came with a gender changer which I needed for use with my USB-serial adapter that I used for configuring the thing.

By the way, I wired my Bluetooth adapter up to receive 12vDC through pin 9, so no separate power wire was needed. Check this out for yourself - I don't want your frying anything if they've changed the design.
