Acceleration technique for catching bluefin tuna

Every year at the appropriate time, there is an activity for catching bluefin tuna. Due to differences in weight and quality, the price of each fish ranges from several thousand dollars to over ten thousand dollars. However, I have noticed a very outdated aspect of the current method of catching bluefin tuna: it usually requires several hours of "trolling" before a fish can be caught. This results in catching only a few fish in a day. I have the technology to shorten this time from several hours to a few minutes, thereby greatly increasing the yield.

This device has a low cost, and its selling price is definitely worth a blue marlin! The key is that there are no similar products on the market at present, so it's a blank market! Although the application range is limited, the exclusive operation brings considerable profits!
