Installed in a boat the former gives an angler a detailed pattern of the ocean floor, along with the fish at the bottom. The GPS plots the boat's position using satellite imaging. But all this scientific stuff should not put the avid fishing enthusiast or the novice off the sport. In fact the sport can be simple and cheap, especially in a country with such a long coastline. One could even catch a rich haul of fish from the beaches or the rocks for which all one would need is a nylon line, some wood or paper to wrap it on, a few hooks and a lead weight.
Fishing according to some is a very absorbing sport.
It draws you in and once you are hooked, you are really hooked, hook line and sinker. The avid fishing enthusiast will tell you that this is a sport that gives one an in-depth knowledge of nature and wildlife, the phases of the moon, the turn of the tide and of course a new respect for the ocean. Anglers also complain of harassment by the Coast Guard, customs and the Navy. Besides, there are no docking, wharfing or towing facilities at the Gateway of India to encourage enthusiasts to have yachts of their own. It is a very rarely played adventure sport.
