Form 10-K for the fiscal year ended January 31, 2005

Lease pool equipment and new equipment sales

1. We note your responses to prior comments one, seven, eight and
nine
with regard to your accounting and disclosures surrounding your
lease
pool equipment and new equipment sales and have the following
concerns.
* You indicate that you have not historically differentiated
equipment
sales as new equipment versus used equipment.  Demonstrate how you
are
able to appropriately classify the cash receipts from the sale of
used
lease pool equipment within your Statements of Cash Flows.  In
this
regard, we believe that the cash receipts from the sale of used
lease
pool equipment should be consistently classified and presented
with
the related cash payments for the purchase of such equipment.
Given
your response to prior comment two that your primary source of
revenues is derived from short-term leasing of equipment and given
the
fact that you have reflected the purchases of seismic equipment
held
for lease within financing activities, tell us why you have not
presented the cash receipts from the sale of used lease pool
equipment
within financing activities.  Refer to paragraphs 16c and 24 of
SFAS
95.
* You indicate in your response to prior comment seven that your
cash
flow caption "Net book value of equipment sold" should be "Net
book
value of lease pool equipment sold".  However, it is still unclear
to
us what this line item represents.  Is this line item actually the
net
book value of your lease pool equipment?  If so, why is it
reflected
within cash flows from operating activity and why does it not
agree to
your cost of equipment sales in your consolidated statements of
operations?
* Demonstrate how you have appropriately reflected your cash
receipts
and cash payments related to your new equipment sales within your
Statements of Cash Flows pursuant to paragraphs 21, 22a and 23a of
SFAS 95.  In this regard, we note that in your response to prior
comment one you indicate that it would take an extraordinary
amount of
time and resources to review the information within your fixes
asset
ledger for lease pool equipment to attempt to isolate the sales of
new
equipment from those of used equipment.
* We note your response to prior comment eight that you only buy
equipment for resale for specific customer orders.  Tell us why,
then,
you include new equipment purchases that have been purchased for
resale for specific customer orders within your fixed asset ledger
for
lease pool equipment.  Given the fact that you do not appear to
have
historically maintained inventory and cost of sales information
for
new equipment sales, help us to understand how you were able to
conclude as you did in your response to prior comment eight that
you
did not have new equipment on hand at any balance sheet date
primarily
because you sell everything FOB shipping point and sales of new
equipment are sporadic.
* You indicate in your response to prior comment nine that you do
not
take title to equipment on consignment. Tell us the amount of
equipment on hand of third parties for which you have not taken
title
as of each balance sheet date as well as the amount of gross and
net
consignment sales recognized during each period presented. Tell us
how
you track and differentiate for reporting purposes inventory held
by
you on consignment versus inventory purchased by you for resale to
your customers.  Clarify what commitments you have as a consignee
of
this inventory.
* You discuss the appropriateness of gross revenue reporting in
your
response to prior comment nine.  We assume that this analysis
relates
to your SAP equipment sales and not your sales you make as a
consignee.  Please clarify and separately assess the
appropriateness
of your revenue presentation of consignment sales.

2. Your response to prior comment four indicates that the increase
in
your cash flows from operations was principally impacted by the
increased demand for your equipment (e.g. income from operations).
We
note however that there were also significant changes in working
capital accounts that you should also fully discuss in order to
provide a comprehensive discussion of your cash flows from
operating
activities for each period presented.

Policies -
Seismic Equipment Lease Pool, page F-8

3. We reviewed your response to our prior comment 11 and have the
following additional comments.
* You disclosed in Management`s Discussion and Analysis that
depreciation expense had decreased significantly during the past
three
fiscal years because certain equipment had reached the end of its
depreciable life coupled with sales of assets with remaining
depreciable life.  Based on your response, it is unclear to us how
you
were able to provide these bases for the decrease in depreciation
expense.  Specifically, how do you know that depreciation
decreased
because certain equipment had reached the end of its depreciable
life,
if, as you indicate in your response, you are unable to identify
and
disclose the cost basis of the seismic equipment pool that has
been
fully depreciated?  How do you know when fully depreciated
equipment
is still generating lease revenue and thus positively impacting
your
results of operations?  In addition, how were you able to
represent
that you sold equipment with remaining depreciable life?  How do
you
identify the net book value of the used leased equipment sold if
your
revenue system is not integrated with your fixed asset system?
* Tell us supplementally and expand your accounting policy to
clarify
when fully depreciated seismic equipment lease pool assets are
removed
from your books.  If you are not able to track lease revenues on a
per
item basis, how are you able to appropriately determine when to
remove
fully depreciated equipment from your books?
* Given the fact that "the Company has not historically tracked
individual assets that have been leased" please explain to us how
you
have determined that you are depreciating these assets over their
useful lives.  Your response indicates that "industry trends" do
not
warrant an increase in the depreciable lives of the equipment in
your
lease pool.  Do you only look to industry trends when determining
the
appropriate depreciable lives for your equipment lease pool?  What
is
the average total period of time your channel boxes and other
peripheral equipment are under lease?  Are these periods longer
than
that suggested by the industry trends you use to assess the
appropriateness of the useful lives of your lease pool?  If so,
please
explain.
* Based on the significant impact the depreciation of your
equipment
lease pool can have on your results of operations, it appears
necessary for you to identify this management estimate as a
critical
accounting policy.  Please provide us with your proposed
disclosures.

4. We note your response to prior comment 12 and have the
following
additional comments.

* As previously noted, your discussion within Critical Accounting
Policies indicated that the company "...is not assured that their
net
deferred tax assets will be realized...".  We asked you to confirm
that an assessment of your deferred tax assets in accordance with
paragraph 17c of SFAS 109 would not change the valuation allowance
you
have recorded as of each balance sheet date presented.  That is,
did
you appropriately reduce your deferred tax assets by a valuation
allowance for the portion of your deferred tax assets, which based
on
the weight of available evidence, is "more likely than not (a
likelihood of 50 percent) will not be realized?"
* As previously requested, expand Management`s Discussion and
Analysis
to address the positive and negative available evidence that led
you
to conclude that a valuation allowance was necessary to reduce
your
deferred tax assets to zero.  Refer to paragraphs 21 through 24 of
SFAS 109.

Additional Comments

Based on your overall response to our prior comment letter, we
have
the following additional comments:

5. We note that your equipment leasing revenues have increased 66%
from 2003 to 2004 and 24% from 2004 to 2005.  Please tell us
supplementally and expand your disclosures to discuss the
utilization
rates for your equipment lease pool for each period presented as
well
as the underlying reasons for the changes in these rates.  In
addition, discuss the impact the changes in these rates had on
changes
in your revenues recognized from period to period.

6. We also note that your depreciation decreased 7% from 2003 to
2004
and 23% from 2004 to 2005.  Given the fact that depreciation is
the
most significant expense related to your leasing revenues, your
current disclosures within the Costs and Expenses section of your
MD&A
regarding depreciation expense is not sufficient enough to provide
your investors with a comprehensive understanding of these
significant
fluctuations and the impact they have had on your business.
Please
provide enhanced disclosures explaining why depreciation expense
has
continued to decrease even in light of the significant increase in
your leasing revenues.  In this regard, we note from one of your
responses that the cost basis of your equipment has been declining
due
to quantity purchase arrangements.  Have there been any other
reasons
for the decrease in the cost basis for your equipment?  Is the
market
price of the equipment declining?  If so, indicate if this
decrease in
the cost of leasing equipment could have any impact on the amount
of
leasing revenue you will be able to generate from that equipment.
7. Revise your statements of operations to include in direct costs
- --
seismic leasing the appropriate portion of your depreciation
expense
associated with your seismic equipment lease pool.  Alternatively,
parenthetically include in direct costs -- seismic leasing line
item
on the face of your statements of operations, the amount of
depreciation expense excluded from such line item, which is
included
in depreciation and amortization.  Refer to SAB Topic 11:B.

Note 3 - Acquisitions, page 6

8. We note your response to prior comment 14.  We note that upon
the
completion of your valuation study on the intangible assets
acquired,
you will make an appropriate allocation from goodwill to the
intangible assets acquired.  It was fully clear from your
disclosures
that the purchase price had not been finalized.  Please confirm
that
if your final purchase price allocation results in a significant
portion of the purchase price being allocated to goodwill that you
will provide a description of the factors that contributed to the
goodwill being recorded.

      Please respond to these comments within 10 business days, or
tell us when you will provide us with a response.  Please provide
us
with a supplemental response letter that keys your responses to
our
comments and provides any requested supplemental information.
Detailed letters greatly facilitate our review.  Please file your
supplemental response on EDGAR as a correspondence file.  Please
understand that we may have additional comments after reviewing
your
responses to our comments.

We urge all persons who are responsible for the accuracy and
adequacy
of the disclosure in the filings reviewed by the staff to be
certain
that they have provided all information investors require.  Since
the
company and its management are in possession of all facts relating
to
a company`s disclosure, they are responsible for the accuracy and
adequacy of the disclosures they have made.

      If you have any questions regarding these comments, please
direct them to Mindy Hooker, Staff Accountant, at (202) 551-3732,
Jeanne Baker, Assistant Chief Accountant, at (202)551-3691 or to
the
undersigned at (202) 551-3768.
