I know right, sparkfun my proverbial candy store. These things have a CRC built in (Cyclic redundancy check), if it fails it will dump the packet and you will never know it. You can turn it off so you might be able to extend the range using the minimum payloads on everything and minimizing...

Depending on how far you want to take this, I would design an rf link using the nordic chip. I have had great success with these rf modules in burst packet mode. 300 meters plus in open fields, through walls at closer range. http://www.sparkfun.com/commerce/product_info.php?products_id=151...

Nothing stopping them from adding a GPS antenna to the tethered low profile buoy they've been using for years at minimal restrictions on depth and speed.
