An ultrasound sensor is a tool that is used to spot marlin. However, the gadgets for fishing are not cheap. Unless you are someone who is dedicated to solely fishing for marlin, be careful of the purchases that you make. Often times companies will make products that are specifically designed for a certain type of fishing, in a certain location, or even a region. Make sure that you do your research before you buy any electronic fishing tool. The one thing to keep in mind about marlin is their will to survive. A fight with a marlin could last for hours without the slightest bit of relief. If at any time you feel like you are becoming exhausted and the fish is still going strong, cut the line. If you land a blue marlin you will feel an exhilarating sense of accomplishment, but there is no achievement that should allow you to put yourself in danger at any time. Marlin fishing should be a hobby, but it is a hobby that should be approached with intelligence. You should always know the strength of your opponent before you take the challenge of a fight.
