Tune-A-Fish You can't beat the up-to-the-minute weather and sea-surface temps provided by XM WX satellite service, but now you can use those eyes in the sky to find the fish, too. The Fish Forecast upgrade feature from WxWorx that's now included with the Master Mariner XM WX package ($50 per month) provides you with the most favorable fishing locations for a wide variety of species based on the analysis of 14 parameters. Between temperature, salinity, current patterns and chlorophyll readings (just to name a few), Fish Forecast spares you the calculations and guesswork and lets you quickly dial in the tuna-or wahoo. It's your choice. WxWorx; (321) 751-9202; www.wxworx.com
