Jon mentioned the accuracy being being a percentage of depth. In an effort to save battery life, I am thinking I should add a digital depth or pressure gauge. My feeling is, if it is accurate in terms of change of depth it would be valuable to have. The question is, is the accuracy short fall a mater of actual depth or change of depth or both? I don't care about actual depth, I just care about change of depth.</div><div>Hank</div></div></body></html>
