Tim,
When you purchased your FishHawk, what other brands were out there? I will be one of the first to admit, it WAS a pain in the but. It has now evolved into a great product. You have to give it to the company. They made the new probe compatible with the old unit. Most companies would have discontinued the old and made an entirely new product. Every one would have to purchase a brand new one. Watch and see, Depth Raider , and Moor will be coming out with a wireless unit in the future. When they do, lets see if they make it compatible with the current models.
