02 Oct 2009 18:33 Designing a depth measuring device

I need to design and make a device that will be able to measure the depth of sea.I am considering to design an echosounder, but if itz feasible than other technologies can also be chosen.

My requirements:

1. The device will be placed in fishing boats and it should be able to measure depth in deep sea,where the average depth is 2000 meters.

2. The device will get a limited amount of power supply,as our plan is to make it a solar powered device.

Can anybody provide any suggestion/reference about this? Thanks.
