This Amendment No. 2 (“Amendment No. 2”) amends and supplements the Statement on Schedule 13D originally filed on February 8, 2006 relating to the common stock, par value $0.10 per share (the “Shares”), of Lowrance Electronics, Inc, a Delaware corporation (“Lowrance”) as amended by Amendment No. 1, filed thereto on March 6, 2006. The Schedule 13D, as amended, is referred to herein as the “Schedule 13D”.

Item 4.

Purpose of Transaction

Item 4 is hereby amended and restated as follows:

On January 29, 2006, Lowrance, Simrad and Navico entered into the Merger Agreement, pursuant to which Navico, a wholly owned subsidiary of Simrad, would acquire Lowrance by means of a cash tender offer and second step merger. On January 31, 2006, in accordance with the Merger Agreement, Navico commenced an offer (the “Offer”) to purchase all of the outstanding Shares of Lowrance, at a price of $37.00 per Share, net to the seller in cash and without interest, subject to certain terms and conditions. The Offer expired at 12:00 Midnight, New York City time on Tuesday, February 28, 2006. According to the depositary for the Offer, a total of 4,105,658 Shares had been tendered and not withdrawn prior to this expiration, including 286,150 Shares subject to guaranteed delivery. As a result of these purchases in the Offer, Simrad, through Navico, became the owner of approximately 80% of the outstanding Shares.

On March 1, 2006, Simrad announced that Navico would provide a subsequent offering period which would expire at 12:00 Midnight, New York City time, on Friday, March 3, 2006, unless extended. On March 6, 2006, Simrad announced that Navico extended the subsequent offering period and that it would expire at 12:00 Midnight, New York City time, on Wednesday, March 8, 2006, unless further extended. According to the depositary for the offer, as of 5:00 p.m. New York City time on Friday, March 3, 2006, a total of 4,425,873 Shares had been validly tendered in the offer and the subsequent offering period to date, including 47,088 Shares subject to guaranteed delivery.

During the subsequent offering period, Lowrance stockholders who had not previously tendered their Shares into the Offer could do so and Navico would promptly purchase any such Shares at $37.00 per Share, net to the stockholder in cash without interest. The purpose of the subsequent offering period was to enable Lowrance stockholders who did not tender their Shares prior to the initial expiration of the Offer to participate in the Offer and receive the offer price on an expedited basis, and also to enable Simrad and Navico to attempt to acquire 90% or more of the outstanding Shares prior to the expiration of the subsequent offering period. On March 9, 2006, Sirmad announced that at 12:00 Midnight, New York City time, on March 8, 2006, the Offer expired. According to the depositary for the Offer, as of the expiration of the Offer, 4,911,856 Shares were validly tendered in the Offer and the subsequent offering period, including 41,415 shares subject to guaranteed delivery. As a result of the offer, Simrad, through Navico, now owns approximately 95.6% of the outstanding Shares. Navico will acquire all of the remaining outstanding Shares by means of a merger with and into Lowrance (with Lowrance as the surviving corporation (the “Surviving Corporation”) under Delaware law. Pursuant to the Merger Agreement, upon the consummation of the Merger, among other things, (i) the Surviving Corporation will be a wholly owned subsidiary of Simrad following the Merger; (ii) each Share of Lowrance (subject to certain conditions and exceptions set forth in the Merger Agreement) shall be converted into the right to receive $37 in cash without interest; (iii) the directors of Merger Sub will become the directors of the Surviving Corporation; (iv) the Certificate of Incorporation of the Merger Sub, as in effect immediately prior to the Merger, shall be the Certificate of Incorporation of the Surviving Corporation and will be in effect until duly amended as provided therein or by applicable law; and (v) the by-laws of Merger Sub, as in effect immediately prior to the Merger, shall be the by-laws of the Surviving Corporation until duly amended as provided therein or by applicable law. Upon consummation of the Merger, the Shares shall cease to be quoted on the Nasdaq National Market System and shall become eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended.
